I have had a look at some of those (including briefly at that one) and they seemed a bit complicated to me. I "think" I have succeeded in making it work reasonably well in the last day or so using my own method which is documented below. Since this is debian, spamassassin is also bundled with spamc/spamd pair which is infact what I use. The only area I am a little unsure on is the check_spam: transports use of $LOCAL_PART - in that will that work for multiple recipients? Steps to follow are 1) edit /etc/default/spamassassin and set ENABLED=1 2) edit /etc/spamassassin.prefs to set rewrite_subject to 0 (see why later) and anything else you want 3) start spamd /etc/init.d/spamassassin start 4) create a file /etc/exim/filter ============ # Exim Filter if first_delivery and $h_X-Spam-Flag: contains "YES" then logfile /var/log/exim/spamlog logwrite "$tod_log From: $h_From: Subject: $h_Subject: Sender: $sender_address" if $h_From: is not "" then mail to $h_From: subject "Re: Your last message to me" expand file /etc/exim/spam-reply.txt once /var/log/exim/spamcount once_repeat 5d endif seen finish endif ============ 5) create the spam-reply.txt (here is mine as an example) ============ Your mail with Subject: $h_Subject: to domain chandlerfamily.org.uk appears to be unsolicited spam. If you intended to contact a person at that email domain for legitimate reasons then our apologies. Please would you resend to the same address but add the prefix "real-" (without the quotes) to the e-mail address and it will bypass the spam filter. Thank you [EMAIL PROTECTED] ============ 6) edit /etc/exim/exim.conf with the following fragments (separated with ============) ============ main configuration message_filter = /etc/exim/filter message_filter_reply_transport = spam_reply_transport ============ transports spam_reply_transport: driver = autoreply user = mail # This transport does a spam check to look for spam and then re-injects # the message into exim check_spam: driver = pipe user = mail group = mail prefix = suffix = command = spamc | exim -oMr spam_checked -f $sender_address \$LOCAL_PART ignore_status = true use_shell = true path = /usr/bin:/usr/sbin ============ directors (my local users bit is a bit weird in real_local:) # This allows local delivery to be forced, avoiding spam filter, alias # files and forwarding. real_local: prefix = real- driver = smartuser local_parts = /etc/exim/local-users user = $local_part transport = local_delivery # All remaining mail is checked for spam spam_to_check: driver = smartuser transport = check_spam condition = ${if eq {$received_protocol} {spam_checked} {no} {yes} } ============== And thats it - it uses the same principals as the other schemes - but these seem to have long complicated perl scripts to do what I complete entirely within exim. I had some problems initially because I was bouncing spam from mailing lists back to mailing lists. I "hope" that using the from: header in the mail filter command will avoid that somewhat. However to check what happens over the next few days/weeks I am writing both the From: header and the envolope sender to the log file to check - -- Alan - [EMAIL PROTECTED] http://www.chandlerfamily.org.uk -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.6 (GNU/Linux) Comment: For info see http://www.gnupg.org iD8DBQE8R0HI1mf3M5ZDr2kRAmsMAJ9hmM9BXwvZ2JDPLz70xlivXRXzNgCgjZ2X ddZjyl9cmgV2zPK8DUTWztg= =KupV -----END PGP SIGNATURE-----
