    We're using forefront protection for exchange 2010 and every once in a while the Cloudmark anti-spam signatures will block important clients from sending us email. Reporting the emails to Forefront-Legit@submit.cloudmark.com doesn't always get the issue resolved, but when we contact cloudmark directly they tell us to talk to Forefront. However, cloudmark isn't sure exactly how we're supposed to engage forefront on this type of matter.

    What phone number or email address can we use to handle these requests without an additional charge?

    I have been working with a Microsoft Support Engineer for over a week now on this exact same issue... Can someone post the resolution to this to help us out, would be greatly appreciated as its proving to be a very stubborn issue.

    That description looks like it's not related to Forefront (but the
    agent log should tell you which agent was responsible). Try enabling
    pipeline and content tracing. If you have a reproducible situation you
    can limit the scope of the trace to just one recipient and keep the
    volume of traces and messages to a minimum.

    We battled this exact same thing.. I ended up calling MSFT to engage the ForeFront Engineers and was basically on the phone with them everyday for for well over a week before a solution was found.. and here is what worked for us:

    1. Obtain the original bounced email

    2. Convert to .EML format (http://www.outlookfreeware.com/ has a tool to convert .MSG format to .EML)

    3. Submit to Cloudmark

     

    Cloudmark has always responded to me very fast but they will always want the original bounced email as it contains important header information required for examining and also they will always as for it to be in .EML

    We had the similar issue with few of our clients. could not find a reason why these msgs are blocked as spam. Most of the time they had a signature with the logos/URLs in it. Only solution that we could think of it was add their mail server to allowed list in our egdge servers.  

    The following recipients returned permanent errors: email@domain.com. Reason: SMTP Server <smtpserver.domain.com> refused to accept your message (DATA), with the following error message: [550 5.7.1 Message rejected due to content restrictions]

     The attachment contains the original mail headers. Please verify recipient(s) mail addresses and try resending this message or contact your IT department with contents of this

    This was the solution for me. Cloudmark was RAPID to respond and agree to remove the flag on my company's toll free number.

    We have been having this issue recently too - lots of our email is being rejected due to content restrictions, even if the email itself is completely blank.

    After some investigation by a helpful customer this has been traced to a hyphen being part of our domain name - does anyone else have experience of this? Apparently Microsoft are aware of this but have given no details of when it will be fixed.

    In the meantime our organisation is having difficulties doing business as we cant be sure our customers are receiving our mail. 

    If anyone can provide a workaround or can help further please can you let me know?

    Fainster, good point.  I could not put my finger on it.  Same problem here most recent message from xxx@et-xxx.com was also rejected due to content restrictions.  This has been puzzling me for months now, and I did not pick the hyphen up.  I've just gone back over the past failures and there it is a hyphen.  There is one rejection however that has a "." in the initial and surname.

    Thanks for posting the hyphen issue, our company is having the same issue of email being rejected due to the hyphen. 

    MS where is the fix?


    On further thoughts this is now happening to other clients without the hyphen.

     we also having same problem with one of our customer. I don't think it is anything to do with hyphen because in our case there is no hyphen.

     In our case only FEP organizations are rejecting the emails probably because cloudmark does not cleanup itself accordingly to status of organization on MXToolbox and other block lists.

    So we've posted the problem to cloudmark in the hope. Let's see.

    Bad part is, Microsoft Remote Connectivity Analyzer SMTP outbound test passes successfully (This is ridiculous).

    And good part is cloudmark did not bounce our message.

    I also have this problem with one of our costumer.

    A workaround is to put there’s IP address to there’s SMTP Server in my IP Allow List and then it worked as a charm.

    Today I came across this problem. I have a server running Exchange Server 2010 with FEX 2010.
    Apparently some fields were entering the SPAM, but I discovered that the problem is in the signature of the sender. The signatures have URLs and Cloudmark identifying this as SPAM because of it. Someone found a solution?

    Hi,

    you should submit samples to Microsoft so that they can fix it.

    http://technet.microsoft.com/en-us/library/bb914008.aspx

    In urgend cases you should open a case with Microsoft.

    Greetings

    Dear Cris, was an update of Cloudmark.
    we need a workaround for this, because are many reject emails and it is impossible to report on all cases. The business of my company are being harmed.

    Please, a gold hint!

    tks

    Hi,

    the only quick solution is to disable the content filter of FPE as long as Microsoft is inspecting your samples or to open a case.

    Hi I have the same Problem

    You need to disable on the Edge Server the Attaxchement Filter Agent

    We search about 3 Weeks with MS!!

    Now it works

    Disable-TransportAgent -Identity "Attachment Filtering Agent"

    I disagree with this solution.  The problem is NOT experienced by any other email service platform, including Google who seem to be able to accurately identify spam in any case.  The issue should not require reducing security or control over spam in any way.  Even adding the domain to whitelist is not sufficient.
