Malformed MIME problem

[yoloits]

My firewall accepts smtp connections and redirects the public IP traffic to
my inside mail server with a private IP address.  The inside mail server
accepts delivers for all inside domains and then forwards them to the
distenation mail server after running the email through MailScanner which is
using Sendmail, ClamAV and SpamAssassin.  The logs show the mail is
accepted, clean and sent on its way.



I have a site with an Exchange mail server running Symantec AntiVirus for
SMTP gateways.  When the gateway receives the email it kicks it back to the
sender because of Malformed MIME file.



Here is the email message that the sender gets back:



Reporting-MTA: Symantec_AntiVirus_for_SMTP_Gateways at winters.org

Final-Recipient: rfc822;druz at winters.org

Action: failed

Status: 5.1.1

Diagnostic-Code: X-Notes; Cannot route mail to user (druz at winters.org).

--- The message cannot be delivered to the following address. ---

druz at winters.org Local processing error while delivering message.



Here is the message the SAV for SMTP Gateways has in it's logs:

Is Mailscanner or maybe SpamAssassin adding something to the header that is
causing the rejection?   Removing the mail server and allowing the mail to
be delivered without going throught the server works.

How can I make this work so I can get the benefits of MailScanner?
