Hi all, Over the past few months, he mailing list has been hit with several bouts of spam. It looks like the same people; they keep changing their IP address and domain name. Before long, they get listed in anti-spam databases, but before that happens, they are able to do some damage. Then they find new hosting and the cycle repeats itself. For the time being, I'm turning on "emergency moderation" in the mailing list settings, which means that every single item posted to the mailing list requires my approval. In the meanwhile, I will think of a better counter-measure to protect the mailing lists. Possibilities: - Allow only mailing list members to post. I don't like this; it creates an entry barrier, and turns away casual users who just want to pop some kind of question without going through a registration process. - Turn the mailing list alias into a moving target. So that is to say, the "ada-mp1@kylheku.com" name can be disabled, or subject to stronger filtering. Liberal posting without membership restriction can be allowed through some alias like "ada-mp1-1234@kylheku.com" or whatever which changes regularly and is only mentioned on the web page. - ??? Cheers ...
