That's nonsense, since there are free and very good solutions against spam
since many years now. If you run your site with Postfix configured to reject
mails from unresolvable and inexistant client and from addresses, this will
bring down your spam volume to about the half. And then add SpamAssassin to
scan the other mails, you can practically forget the spam issue. Just add
ClamAV, and you don't even have to bother about viruses. You would be
surprised. I've never undestood why site maintainers complain about these
issues despite the available means to fight against them.
To think it was only a short time ago when we discussed trying to teach
ones grandmother how to steal sheep.....
At any rate, the issue isn't blocking incoming email, it's spammers
subscribing to the list via the MailMan web interface. When you
subscribe, it sends a verification link to the address you subscribed.
Those happy little spammers have software that will happily go to the
enclosed URL in order to "verify" that the requestor actually wanted to
be subscribed to the list.
Of course, if you WANT spammers subscribing to your mailing list so you
have to play whack-a-mole with them....
