Exchange 2003 And Spamassassin

[Jan Englund <ja...@gmail.com>]

Hi
We are running a Exchange 5.5 and Exchange 2003 mixed mode environment.
Since introducing Exchange 2003 servers we do not get any message
headers from the spamassassin relay sent to users on the Exchange 2003
box.

ive seen other people experiencing this but my question is if Exchange
2003 is supported by Spamassassin and if so if there is anyone that
has found a solution to this.

Thanks
Jan

I use SA as a border gateway to Exchange 5.5, 2000, and 2003 servers in 
a dozen or so locations. I have no problem with headers or any other 
aspect of spamassassin.  Exchange does not strip headers, however 
Outlook and Outlook Express do!

But...

Are you using your 5.5 server as an SMTP bridgehead to your Exchange 
2003 infrastructure?  If so, there lies your problem.  In many cases 
(depending on configuration), the entire SMTP envelope will end up being 
replaced with an X.400 address to accomodate internal site routing. 
This is a total rewrite of the header and could be the cause of your 
problem.  If you are using Exchange 5.5 as a gateway to an Exchange 2003 
mail system, then the problem will go away once you finish your upgrade.

Also (just a semantics thing) Spamassassin is simply a tool to score 
email. Your linux/unix MTA, likely using sendmail or postfix, is a 
managed relay host consistent with all RFC's. It is not up to 
Spamassassin to "support" Exchange or any other product except for Perl 
perhaps.  Microsoft, on the other hand, has a ways to go on correctly 
adhering to RFC's.  So the question should be, "does Exchange work 
properly with Spamassassin?"

Am I nit-picky or what???

Exchange is stripping the headers off. No doubt theres a stting buried 
somewhere where you can tell it not to, but I have seen this problem 
before in Ex-2000  (for passing emails to a folder dor sa-learn to pick 
up). Never found a solution, but then I'm not an exchange admin/user 
so..probably something to do with group policies..
