Keeping your junk e-mail filter updated

The tactics of spammers and the content of their messages are constantly evolving. For this reason, just like antivirus applications, the Outlook 2007 Junk E-mail filter’s effectiveness heavily relies on keeping its data file up-to-date.

Each version of Microsoft Outlook that contains a junk e-mail filter receives updates to the data file (outlfltr.dat) as part of the Microsoft-wide monthly update released on the second Tuesday of each month.

The updated outlfltr.dat is the result of the evaluation of hundreds of thousands of spam messages and constantly increases the filter “catch” rate for incoming junk email.

The recommended way to obtain updates to the Outlook Junk E-mail filter is by turning on the Automatic Updates option in the Windows Security Center (both in Windows Vista and Windows XP SP2). By turning this option on the Outlook Junk E-mail filter updates will be automatically downloaded and installed on you computer as soon as they are released. If you instead wish to download the updates manually, you can either select the “Check for Updates” option in the Outlook 2007 Help menu or by going directly to the Microsoft Update site.

We just released the latest update on Tuesday 7.10, so this is a great time to update. In the meantime, drop us a line. We want to hear from you about your experience with the Junk E-mail Filter and how we could make it better for you. Use the contact form on the Email link above.

Thanks!

It's great that the Outlook junk mail filter is updated often. But it junk mail detection is not as good as Hotmail's. In fact, the Outlook junk mail filter triggers a lot of false positives.

(will mail this as well)

I would like to know why a certain message got flagged as spam: spamfilters like SpamAssassin give the reasons for a high spam score, so if you receive legitimate email, you can check why it was flagged as spam and for instance notify the sender that some mail server setting is causing their mail to get a high spam ranking.

Furthermore I would like to be able to enable or disable the junk mail filter for each account and to be able to set the junk mail folder for IMAP accounts.

For me this works great for a long time. Only thing I miss is the possibility to add more then one sender to the junk-mail list. Now you can add only one sender a time.

I'm still getting a bit through - mainly phishing messages about Banking. These seem to be picked up as Phish but moving them to Junk would be of benefit to most users.

Ruud Groeneveld suggests here to allow multiple selections to add to Junk. Well, that has never been an Outlook feature but is certainly a desirable one and one that has been requested many times.

Jorrit Schippers suggests informing a user why a message was marked as Junk. Not a good idea! If you inform a user then you essentially show how the Junk filter can be passed.

Joshua,

Without looking at the original mail and knowing what the recipient junk email filter settings are (and also if they use other anti-spam applications on the server or server side) it is difficult to determine cause. Have you been able to repro the issue yourself or within your organization?

Alessio or other Outlook Pro's,

I am also curious how I can investigate why an email goes to junk.  

Recently an email was sent from our website using mailto.  Therefore it was sending via their method of sending new mail.  The only things I noticed where that 1) the subject line was empty and 2) the domain name had a hyphen in it.  

We are using Exchange 2007 and Outlook 2003 with automatic updates turned on.

Alessio Roic said:

Peter,

sorry for the late reply.

Determining as to why a message is moved to the Junk E-mail in Outlook folder is not an easy task for a multitude of reasons. Suffice to say that the Junk E-mail folder can be used by other anti-spam filters to get rid of spam. This includes Exchange 2007.

What you might consider doing is what our friends and colleagues in Exchange describe on their blog (http://msexchangeteam.com/default.aspx) and turn on the display of the SCL and PCL values in the message internet properties - that will allow you to determine whether it is Exchange that identifies the email message as junk.

I find that the Junk mail filter doesn't work well.  Mail is getting into my Inbox that is tagged as Bulk and is not filtered to the Junk Mail box.  Furthermore, I'm finding that Spammers are changing IP's and gateways to get that Junk mail to you.  I think that Microsoft should work on a way for users to input / block IP's as well as domains.  That would enable us to have more control over that Spam getting to us in the first place.

Alessio Roic said:

Dwight,

thanks for the feedback.

Yes, it is a common practice for spammers to switch IPs or to use IPs they have obtained unlawfully from other users. However allowing to add IP addresses to the blocked senders list wouldn't be too effective measure:

- spammers change IP addresses very rapidly - by the time an Outlook user has added an IP to his blocked list, the spam attack originated from that address will have ceased and it will unlikely occur again.

- in the long run, as IP addresses are reassigned by providers, blocked IPs would generate false positives with legitimate users' mail being junked due to a spammer having used that IP in the past.

Having said that you do raise valid points indicating that the battle to thwart spammers is an ongoing one. We will continue striving to make their life harder while ensuring all good mail gets to your Inbox as expected.

Keep the feedback coming!

Dwight Cole said:

Alessio,

get feedback about the IP's.  I've also considered that most of the true spammers who have too much time on their hands also all use a gateway.  That was they think that no one can get the really endpoint.  I also know that they also can't hide the hostname.  Any good IP search engine can do a reverse lookup and find the IP and the hostname in moments.  The header that you get from outlook also gives you the gateway the message came from.  While this may not be the answer I would hope that MS is looking at ways to assist the end user with blocking these types and "profeesional spammers".  Its widely known that email and inbox clutter is an expensive issue for corporations.  Blocking everyone not in your address book is, at best, a bad way to go and can also be very unproductive going back and forth until they are let in.

I've been having trouble with my Junk Mail filter. I mark an e-mail as not junk and add the sender to the safe senders list but the very next time it will still go to the Junk Mail folder. Also, whenever I do a search for text that I know is in an e-mail within a folder or even a all mail item search. Outlook fails to find said text. Which means I have to manually search and find the e-mail.

Alessio Roic said:

Melissa,

the messages coming from GAL addresses should still be honored and bypass the Outlook junk email filter - no changes in this area took place between 2003 and 2007.

I would suggest you take any message that is coming from the GAL and that is automatically moved to the junk email folder, and verify its Internet properties (you can do that by looking at the Internet headers properties of the message - open the message, expand the Options section of the ribbon - the internet headers section is at the bottom of the Message Options dialog). If you find the following line: "X-MS-Exchange-Organization-SCL: -1" then the message was stamped correctly by the Exchange server as an internal organization message. If not, then I would assume something has occurred on the Exchange server side that changed the behavior. Let me know your findings.

Thanks

Mike,

there could be several reasons as to why the mail still gets junked. Without looking at the message itself and at other settings it is hard to make an accurate diagnosis, so I will make a short list things to consider.

- Verify that the sender address and/or domain is not in the blocked sender list.If it is, remove it and observe if any changes take place.

- Consider that some filtering might also occur on your IP side - it is not uncommon for IPs to provide some antispam protection, and this could have messages moved to the Junk E-Mail folder automatically without Outlook intervention. If you're not sure I recommend contacting your IP to verify.

I send an email to myself and Outlook 2007 puts it in the junk mail folder. The spam assisin score is .3

Does this mean that somehow, the sending domian is on the "hidden" spam list that Microsoft includes in Outlook and uses to filter mail in Outlook.  Does anyone know how to get a domain off that  list?

The mail was sent by Lyris, a well known mass emailing program.  Is that the problem--Lyris in the header?

My domain is rideagainstthemachine.com and I use Google Apps for domains to send email.  It got sent to everyone's junk folder back when I had my own email server as well.

I'm not sending to multiple people or even remotely doing anything that might seem spam-related.  How in the heck can I troubleshoot this?

Same comment as Ruud Groeneveld - I'm using Windows Mail on Vista and you only seem to be able to add senders or sender domains to either safe list or blocked list one at a time.  I have email folders full of emails that are all obviously junk so would be much nicer to be able to just mark them all and add to blocked list in one go!  That would be a really great update to receive :)

I have my own domain and several other that are hosted on the same server. Every time I send a message to an external email address it gets sent to the recipients Junk folder if they are using Outlook.

My domain is valid, not on an IP blacklist anywhere that I can find.

The domain it's self is for a business with legitimate content that is not related to anything dodgy. How do you tell Microsoft to STOP marking my emails as Junk? Who do I have to contact?

Like so many of the above, ALL my incoming mail is placed in the junk mail folder even though I have marked the sender as safe.

This is not an IP issue and the send is not blocked.

Reading through the net it seems that it is the sp3 that has caused this.

Seeing as we have all paid a handsome amount of money to Microsoft for the use of this programme, perhaps they could actually admit to the problem and tell us how to fix it.

It is now having a serious impact on my business.

Does anybody hava a fix?

First of all I would like to thank all those that have left an email address available and I have been able to contact. I'm also glad to say that in the majority of the cases I have examined so far the cause of messages being incorrectly marked as junk was not the Outlook filter, but other non related processes that leverage the Junk E-Mail folder.

As for NYMike and Bryan CLark's issues:

as stated previously for similar customer reports, there could be several reasons as to why the mail gets junked. Without looking at the message itself and at other settings it is hard to make an accurate diagnosis, so I will make a short list things to consider.

- Verify that the sender address and/or domain is not in the blocked sender list.If it is, remove it and observe if any changes take place.

- If your outgoing message is marked as junk, recommend your users add your domain to their safe sender list. This will automatically make your messages bypass the Outlook junk filter.

- Consider that some filtering might also occur on your IP side - it is not uncommon for IPs to provide some antispam protection, and this could have messages moved to the Junk E-Mail folder automatically without Outlook intervention. If you're not sure I recommend contacting your IP to verify.

Dear Alessio

Your latest answer seems to repeat what you have said earlier and does not provide a solution. I can confirm that:

1. Everyone on my safe sender list is still being put into the Junk folder.

2. I have checked with my IP and it is nothing to do with them.

I would appreciate a solution to this problem that appears to be caused by Microsoft's own SP3!

This is seriously impacting my business now.

Is there a way to enable some sort of logging to see exactly what the junk emai filter is doing?  The reason I ask, is that I have a user that is on OL2007, his mailbox sits on an E2K3 server.  On, or about, 2/4/2008 messages completely stopped arriving in the Junk Mail folder.  I am the network admin here and i have not put any changes in place for any kind of spam filtering.  The concern is, that the user, from time to time has a legitimate email get put in the junk mail folder and then "adds to safe sender list", which has always worked.  He is used to seeing roughly 10 or so new emails in his junk mail folder daily.  As I stated earlier, this stopped completely on 2/4/2008.  He has received ZERO email in his junk mail.  How can I tell what the junk mail filter is doing?  How can I test to see if it is even working?

Alessio Roic said:

Mr. Mendez,

on the Outlook side there is no logging available for the Junk Email feature - the main reason being that any such capability would mainly used by spammers to determine what messages are able to bypass the filter.

As for your user issue - I would like to understand the issue more clearly. Is it that the customer is not receiving messages he is expecting either in the Junk folder or in the Inbox? Or that no messages are moved to the Junk Emial folder? If the former, the only thing I would consider checking in Outlook is that the "Permanently delete suspected junk e-mail instead of moving it to the Junk E-Mail folder" checkbox is not selected in the Junk Email Options tab.

The other thing you might want to consider doing (as recommended previously) is what our friends and colleagues in Exchange describe on their blog (http://msexchangeteam.com/default.aspx) and turn on the display of the SCL and PCL values in the message internet properties - that will allow you to determine whether it is Exchange that identifies the email message as junk.

Mr. Williams,

- It is not possible to eliminate the Junk Email folder. The Junk Email folder is one of Outlook "Special Folders" (like Inbox, Calendar, Task, Deleted Items, etc) and as such they can't be turned off. Also consider that numerous 3rd party antispam solution leverage that folder to run their filtering.

- As for the messages being moved to the Junk Email folder when settings are set to "No automatic filtering", this is a series of things that have helped other customers that have reported the same issue:

- if a message is from a sender that is part of the blocked sender list, it will still be moved to the Junk Email folder even with the option set to No automatic filtering. Check the blocked sender list content and see if it contains any addresses.

- Some users have found they had rules movng messages to the Junk Email folder. This is more of a rarity, but worth checking out anyway.

- Last but not least, some 3rd party antispam solutions do leverage the Outlook "Junk Email" folder and move messages there as a result of their message analysis. Provided it is not possible to determine whether it was Outlook or another application junking the message without examining the specific message itself, one easy way to determine if there some filtering running outside Outlook is this: if the messages in the Junk Email folder have the subject marked with a stamp such as "[SPAM]", then a non-Outlook filtering is running on the inbox. This is because Outlook does not stamp messages identified as junk with any sort of label.

Let me know if this helps.

Alessio,

none of your suggestions are valid in my situation. 1, none of the mail that makes it to the junk folder are in the blocked senders list. Another observation is that much of the email that ends up in the junk folder is form senders whose email gets through to the inbox regularly, bot before and after the junk email. I only have 3 addresses in the blocked senders, all from china.

As I said in my original post, I have the junk email set to no automatic filtering. However, when email does get into the junk folder, I get an outlook popup that tells me about it. When I click on junk email options, 50% of the time it shows no automatic fileter, bu the other times, Outlook has changed that to LOW by itself.  This is a real problem as most of what it catches as junk is actually legit email and it has cost me business..

Any help you can give....

# March 28, 2008 4:14 PM

Alessio Roic said:

Mr. Williams,

sorry my previous directions proved fruitless.

I have a few additional questions:

- What type of email account are you using? POP? IMAP? HTTP? Exchange?

- Could you tell me more about the Outlook popup you mention in you latest post? If possible I'd like to see the text it displays.

- Was Outlook installed from CD or through an administrative installation point? I'm asking because in the latter case it would be possible for an administrator to edit the Junk filter options to switch back to a admin-defined level using the Configuration Wizard.

I have been having the same problem as may others have reported. Starting sometime approx 2 months ago many legitimate emails have started going into my junk mail folder for no reason. This includes emails from those I have previously and regularly received with no problem, as well as almost all, if not all email I receive from a source for the first time (e.g. purchase confirmations, email from new customers, etc).

My junk mail filter is turned off completely, there is no filtering set at my ISP, and I have no other spam filtering installed. I have disabled my firewall (AVG free) as well as Spyware Doctor and Spybot S&D, to no avail. I have searched my blocked senders list, which of course does not contain those addresses.

This absolutely just began happening within the past 2+ months. There are so many updates pushed out by MS that I would have no idea what to try and start reversing. I have XP Pro SP2, Office and Outlook Pro 2003.

With all the reports of this suddenly starting I would say this is clearly an MS problem. I have seen people surmising that it is related to SP3, but I am still on SP2, but again this is new behavior, never had this kind of problem previously.

I tested with various SMPT & with our other 2 exchanges servers... and it doesn't go in junk mail. It only does with that new server.

How is this possible if the new email is completely free from any bad reputation. Is the problem with our exchanger?  or is there anything i can do in OUTLOOK 2007 to prevent any of my emails to go in junk of my clients?

As in many of the previous posts, we have experienced an alarming and very sudden increase in the number of 'false positives' being sent to the Junk E-mail folder.  In my case specifically, I have the Outlook Junk E-mail option set to No Automatic Filtering - and yet e-mail messages that have NEVER been filtered out before are now ending up in the Junk E-mail folder.  It seems to me that if the filtering is set to NO filtering, and I receive a message from a sender who I have NEVER received from before, then logically that message should NOT end up in the Junk E-mail folder unless the Outlook filter is broken.

I note that the most recent Junk E-mail Filter update (KB943591) I have installed on my system was installed on 1/9/08 - just about the time that many folks here began having problems with the false positives in the Junk E-mail folder.  In our case, we implemented an Exchange 2003 server about a month ago - and immediately the Outlook Junk E-mail filters within our company began malfunctioning.

We currently use Trend Micro Client/Server Security for SMB as our Exchange/desktop filtering system.  This product creates its own SPAM folder within Outlook; as such I find it doubtful that it would ALSO use the Outlook Junk E-mail folder, and thus just as doubtful that the Trend Micro software is the cause of the malfunctioning Outlook Junk E-mail filtering.

I would suggest that this problem may be a combination of MS Exchange Server and the latest Junk E-mail filter(s) available from Microsoft).

I would also suggest that maybe someone in the MS R&D realm might consider doing some testing to find the cause of this obviously flawed behavior, rather than repeating suggestions to 'fix' the behavior that are either irrelevant or ineffective.

Is there any documentation that explains what antispam features are manageable thru Outlook junk e-mail filter and what features are only manageable on the server side?

Is it possible to bypass, for example, the rejection (complete) of a message, against exchange more restrictive behaviour?

Thanks a lot

See, I'm having an opposite problem.  Recently our junk email folder has just stopped working, period.  The filters haven't been turned off but there's a little red "restricted" circle on top of the folder and I don't know how to get rid of it.  Now all mail is going into the inbox and we're getting over 100 spam messages daily.  We're a business and it's wasting a lot of time sorting through all the junk mail to find actual costumer messages.

Hi, I hate to chime in with the same question as everyone else, but I am really desperate for some more information on how/why Outlook Junk E-mail filters items.

We have a standard RFC compliant / plain text mail that originates from one of our own web applications which is consistenly filtered into the junk mail folder.

Our junk mail settings are defined via Group Policy. We have no 3rd party tool that leverages the Junk Mail folder and IMF is not configured. While an internal solution is readily available - add our domain to the safe senders list using Group Policy I am concerned about our external clients Junk Mail configuration and how we can limit the risk of being blocked by clients outwith our control.

I have registered with MSDN blogs, please contact me and I would be happy to share the header/body of the mail in question.

Thank you

What Outlook desperately needs is to dump the filter updates and go with a Bayesian filter like Mozilla Thunderbird uses.

Thunderbird's filter is 10x better than Outlooks. And when it's sure what is or isn't spam it asks you.  After very little training it works like a charm.

Outlook's filter is pure crap.

I dropped Outlook several years ago.  I decided to give Outlook 2007 a last year shot and nothing has changed with regard to the filters.

Oh and Microsoft still hasn't figured out message quoting..but that's another matter.

Alessio,

I have just spent all day trying to get a mailing through the junk filter. After about 6 hours (I kid you not), I have determined that adding a few characters to the end of the subject of the email will get the message through (not moved to Junk folder). I have literally added " ..." to the end of the subject, and nothing else. (Needless-to-say, I tried a few dozen other possibilities).

It seems to me that this is a bug; that a junk filter scan should not return different results based on punctuation.

For now, a 10 minute email preparation has taken 6 hours and 10 minutes.

Any suggestions for future mailings?

I am using Vista Windows and Outlook. Under Favorite folders in Outlook there are: Inbox, Unread Mail, Sent Items and somehow system created folder "Inbox for one of my e-mail addresses". If I try to delete e-mail in that folder, it crosses out the e-mail but not deleting it. How to delete permanently or send to junk e-mail because 99% is junk mail? Every day I am getting more junk which I cannot delete.

I would appreciate your help.

Question one: Can a user create a custome filter list in Outlook for the "from" and/or "subject" fields in email?  I get repeted email where the Outlook "from" field is CNN Alerts and where the Outlook "subject" field is CNN Alerts: My custom alert.  If I could block on the field name I would solve one problem.

Question two: Can an Outlook user block email by any given word in the content of the email; i.e. pfizer?

In other words I would like to create my own custom list of "content" words that I want to use to filter junk mail by.
