Background: I have MIMEDefang running (with multiplexor and embedded Perl interpreter) on a Linux box that serves, by way of a mailertable, as an MX for another server. This second server runs Netware, hosts the actual mailboxes, and provides pop service.
Whether or not you think it's a good idea, I need to give users the option of discarding messages with SpamAssassin scores above a certain threshold. Such messages should be discarded at the server running MIMEDefang, before they reach the user's MUA. Right now we tag them with the X-Spam-Score header in the usual way. One approach I'm considering is a configuration file on the MX that would be a table of envelope recipient addresses (or recipient regex's) and score thresholds. If a recipient matches an address (or regex, if I go that route) in the config file, the threshold is compared to the reported score to determine whether to discard the message (for that user -- see below) or just tag it as we do now. What would be a good way to approach this? The first thing that comes to mind is putting the file in /etc/mail/ (say /etc/mail/mimedefang_user_prefs.cf), read it in filter_initialize(), and then use it in filter_end() somewhere after spam_assassin_check(). Another issue: how to handle one message with multiple envelope recipients, not all of whom have the same policy. I need to RTFM and think about this a bit more, but would it be relatively easy to strip some recipients in filter_end(), and leave others, before the message is forwarded through the mailertable mechanism? Thanks. -David _______________________________________________ NOTE: If there is a disclaimer or other legal boilerplate in the above message, it is NULL AND VOID. You may ignore it.
