Dears,
I'm actually using SA (through amavisd-new) + postfix + postgrey and user's
accounts are on a postgresql database. I'm also using dcc, pyzor, razor and
spamcop plugins.
I see some spam is attempting to go to unexistant mailboxes, perhaps in an the
hope the MX is configured with catchalls. I was thinking that probably it could
be interesting to detect mail going to unexistant mailboxes and have them
reported to bayes, dcc, pyzor, razor and spamcop.
Since even legitimate mails may be misdirected, ie: when one of your users
misconfigures the reply e-mail address in his/her MUA or when he/she
communicates a mailbox to someone by voice, I wouldn't like to adopt the
pragmatic approach of regarding every and each e-mail directed to an unexistant
destinator as spam. I would instead prefer to use a more heuristic approach,
like, in example, handling as SPAM only e-mails to destinators whose mailbox
name is at least a given distance (say 3?) from every alias name in that domain.
That said:
1) did anybody you setup anything like this?
2) which may be the unwanted side-effects?
3) do you think this kind of feature would be somehow useful?
Thanks,
