Re: How would you provide a 554 rejection notice for spam?

2007-07-31 Thread dalchri

Well, I setup MIMEDefang.  Everything is working as I want except that the
(fake) rejected mail does not make it through the milter to Exchange.  I
used action_bounce to reject the message in mimedefang-filter.

Is there a way to send the rejection code but still get the message through
the milter?

I think I might be leaning towards Exim for it's fake reject feature if I
can't get this to work.

Thanks for all the feedback!

How would you provide a 554 rejection notice for spam?

2007-07-29 Thread dalchri

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?

Force autolearn=ham for manual whitelist

2007-07-23 Thread dalchri

Hello,

I completed configuring all my network tests and the bayes database has
passed 200 ham messages and is being used.  The bayes database has been
accumulating knowledge so far through autolearn.

I was concerned about how one sided the autolearning has been since over 90%
of our email is spam.  To avoid FP, I put our customer database of email
addresses into a manual whitelist.

Although these addresses are making it through fine, only a few are being
reported as autolearn=ham in the X-Spam-Status header, most are being
reported as autolearn=no.

Is there any way to force these messages through the autolearn process?
