Right now I am using system filter to deal with some bad senders and sender_domains, but I am wondering if we can have such functionality included in the main exim.conf with the option of adding the sender addresses and sender domains in files in /etc/exim/some-files. I love keeping my exim.conf as close to the one in the distro as possible, but for some reason I don't see the most appropriate place in exim.conf to insert the rules, such as: deny message = Users have complained that you send unsolicited mail.\n\You're therefore blacklisted.\n\ Please contact abuse(a)crownkenya.com senders = ${if exists {/etc/exim/blacklisted_senders}{/etc/exim/blacklisted_senders}{}} Thanks guys and have a great week. -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254 7 3200 0004/+254 7 2274 3223 "Oh, the cruft."
