Many folks "frontend" their Exchange servers with a unix/linux
sendmail/qmail/exim/postfix server.  The linux box becomes your central
email "hub" for the enterprise and all email is properly "masked" to appear
to come from a single ip.  It is also a handy place to implement things like
SpamAssassin, RBL's, and preliminary Anti-Virus and Attachment policy
enforcement.

Subject: [isalist] Publishing an Exchange Server and email still going out
through the default IP


http://www.ISAserver.org

I have posted in the past on this topic and no one seemed to have any
ideas...

Essentially our ip for our exchange server is xxx.xxx.xxx.150 but our
default ip for isa is xxx.xxx.xxx.131. All our outgoing mail still appears
to be coming from 131.

Does the newest ISA help with this issue?

Thanks!
