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? -- View this message in context: http://www.nabble.com/How-would-you-provide-a-554-rejection-notice-for-spam--tf4167751.html#a11857500 Sent from the SpamAssassin - Users mailing list archive at Nabble.com.
