I've recently put SpamAssassin in front of my Exchange server as an SMTP
proxy. Our previous spam filter would provide a 554 rejection notice for
anything that was identified as spam. This meant that any FP would be
notified so that email would not get silently ignored. Although a
rejection
notice was sent, we still retained the spam. This meant that when our
users
got a call from their customer about the rejected spam, they could
quickly
locate the message without it having to be resent.
I would like to continue doing this with the new SA/Exchange setup.
Right
now I use spampd but I would like to change to Sendmail just because it
is
part of the default install for Redhat.
How would you go about providing a 554 rejection notice? Would you do it
on
the SMTP proxy? On Exchange? Would you use Sendmail? Postfix?
Something
else?
a milter from sendmail, provided you wish to stick with sendmail.
mimedefang springs to mind, but I have no experience with it.
Any idea for qmail?
