This can be a complex issue in the end, but its a simple enough question. First some background:
Ever run a courier server (of course!), and have SMTP off for anyone not authorized in the accept domains list (of course as well!), and yet still get HUNDREDS of spammers ~trying~ to use your server for relay? I have, and am. Our email server had a nasty hiccup in DNS for a day, and the backlog got so massive that its taken 24 hours for it to clear out. Watching the screen race by under "tail -f /var/log/maillog", I notice a crudload of deferrers and access denies for all sorts of junk mail accounts that do not exist on our servers, or any of our clients. Its quite crazy really. The one that gets me is the 50 lines that shoot through ever few minutes to "[EMAIL PROTECTED]". ?! Anyhow... I've come to the conclusion that I want to squelch all this outgoing deferrals. So the big question to ask: Is this possible? I wish to have courier simply "throw out" anything that it would normally not deliver or relay. All our clients know how to use our server, and an error is just more traffic on the internet to bounce around. I'm not so much concerned on the actual "Failure" notices that go out, but rather all the deferrals. Those tend to just pile up, because they keep coming back until so many deferrals have been reached that it sends a Failure. Quite annoying. Scenario: spammer sends mail out trying to use your machine, machine goes WTF NO! and instead deffers the message, message then comes back again, and again, and again, then it finally fails and courier sends a failure notice, then the failure notice comes back to courier because that original emailer address doesn�t exist from where they sent it (typical spammers), then THAT returned failure notice gets filed into the deamon account on your server. Grr. Simply, instead of a status; deferred message, can courier just 'ignore' it ? Throw it into /dev/null ? Or take the mail like it was GOING to send it, but doesn't ? =) (And don�t give me some bull about "that�s how the old internet has worked and its proper procedure to do that". Guh... Its because of 'that', email servers get bogged down from these idiot spammers!) -Randall Shaw ------------------------------------------------------- This SF.Net email is sponsored by Sleepycat Software Learn developer strategies Cisco, Motorola, Ericsson & Lucent use to deliver higher performing products faster, at low TCO. http://www.sleepycat.com/telcomwpreg.php?From=osdnemail3 _______________________________________________ courier-users mailing list [EMAIL PROTECTED] Unsubscribe: https://lists.sourceforge.net/lists/listinfo/courier-users
