Dear Monks, It is probably to good to be true but I've come up with yet another antispam idea, and am curious about which module to use. There is a writeup but basically I want not to filter by content, but to create virtual email addresses often and wipe out old ones.

Note: This is naive and I just thought of it today. Maybe it's been done before or has some fatal flaw. Also I don't have experience with sendmail filtering. Anyway, to see if it works, I need to choose a base SMTP server implementation (in perl of course). I am guessing this cannot be done with just Sendmail::PMilter.

So, does anyone have experience to help choose which module to use as a base? Candidates seem to include Sendmail::PMilter, Net::SMTP::Server, NetServer::SMTP (though old), Net::SMTP, POE::Component::Server::SMTP (though it is an empty husk), and Net::Server::Mail (which looks nice). At the moment I'm planning on jumping in with the last choice.

Thanks for your help!

Matt R.

UPDATE: Thanks tirwhan, I had not seen the very similar idea posted a month ago by tomazos. How wierd. I've updated my page with the info and replied to him too since he thought of it first. Though with a slightly different focus, I think his replies to the standard "why your antispam solution won't work" form letter also apply to mine too.
