MS Forefront header code included in Emails

Hi,

I've been experiencing header code being included in emails from time to time when the sender is using Exchange or Office 365 MX records.  Not sure if there is a difference between the two.  I am using a IceWarp mail server and the email lists the characters below as MS Forefront Anti-Spam Report.  I've talked with IceWarp and they are following all of the RFC specifications.  Any insight is appreciated.

Emails start off with code like this:

SFV:NSPM;SFS:(10009001)(428001)(365934002)(189002)(51484002)(199002)(2525140
10)(377454003)(48214007)(76786001)(87266001)(4396001)(85852003)(76176001)(19
300405004)(19613025002)(83322001)(19609705001)(50986001)(47976001)(80976001)
(69226001)(95666003
      
)(19580395003)(17760045001)(19580405001)(81816001)(16236675002)(18206015023)
(87936001)(81542001)(2656002)(33646001)(49866001)(83072002)(85306002)(767960
01)(54316002)(217423001)(94316002)(81342001)(74316001)(74366001)(79102001)(9

That code should be in the headers.  Is it visible in the body of the message?  And Everyone claims to be following the RFC's.

It displays in the body of the message as well.  The original is still present, just along with all of the header information too.  Only seems to be happening every now and then.  I'm going to see if disabling Postmarking will have any effect on the problem for the user.

Are these messages 'forwards'?  If so, it may be a formatting problem.  Over that last 20 years, a lot of email clients get the formatting wrong in forwarded emails.

I spoke with our Firewall/SpamFilter provider and it is possible that it is a bug in the software version.  After it checks for Spam it is not always closing the header properly so the entire message gets corrupt.  I will be upgrading the software soon to see if it will fix it.

Our firewall was causing this by corrupting the email headers.  Upgrading to the latest firewall version solved it.
