No, it is not because of Trend antivirus or emanager. Spam filtering is
complete outside the Exchange world. People on Exchange 5.5 servers receive
email messages fine with all headers kept intact. So I am suspecting
Exchange 2003 servers remove any headers added by spam filter.

If you are using Trend to filter...it will not because of the scanning
technology ESE API, compared to it's earlier predecessor of Emanager
MAPI/AVAPI that can scan the header.

Subject: SMTP Header issue
I'm running a mixed-mode Exchange 5.5/2003 environment. All Exchange
servers
(5.5 and 2003) talk to a Exchange 5.5 IMS.
My issue is this: When users receive SPAM, we have a service tagging the
SMTP header with "X-SPAMCHECKER: Yes" values. Since the implementation of
Exchange 2003, the users migrated to the Exchange 2003l server do NOT get
this header modification. Any ideas?
Thank you,
Wei Yan
