O.K. nice discussion about that, but how we do get rid of this bots? A simple reauthentification, that you are homan, like on postfix-users list would help a lot. If you are a bot you can't answer the sign-up request.
removing the Reply-To from the subscription mails would probably also do something to help. That would at least make it more difficult to subscribe the support addresses that reply automatically with some "your mail has been received" mail
You mean...? you mean the way this robots get subscribed is a) somebody (anybody) sends an email to the subscription address, claiming to come from the support address of some bussiness, for example. b) The ezmlm program sends back a confirmation request, c) the confirmation request is duly answered back by the robot program there d) the robot is subscribed. :-O This could even happen with viruses sending ramdom email... but the funny thing is that they happen most in this list, they are rare in SLE, for example, which has much more traffic. Then, perhaps are they malicious intentional subscriptions by somebody? :-( There are two possible things to do. One, is to save the subscription request, for later analysis, to help determine how/who is doing this. Two, make sure the confirmation email is answered by a human person, possibly by answering a simple question (possibly random) like how much is 2+2. This would probably need modification of ezmlm (I have never used it, so I'm guessing) because it is designed to ignore the contens of email, it works on the "TO" address alone. -- Cheers, Carlos Robinson
