What happens if a spamer sends email spam to my hamtrap@email.tld

I have begun to use the bayesian system with spamtrap@email.tld and hamtrap@email.tld, but how i block the spamers to send spam emails to my hamtrap mailbox?

Well, I shared your concern as well -- however, I poked around in the code a bit and it appears as if they attempted to account for that :-)

Essentially, each Virtual Server receives their own hamtrap and spamtrap aliases -- which dump ham and spam into special mailboxes just for that Virtual Server.

Once an hour or so, spamtrap.pl runs, and processes those.

When it runs against each mailbox, it compares the sender against a list of all valid email addresses for that domain and it's aliases -- and if the sender isn't defined in the Virtual Server, the email is ignored.

Feel free to take a gander in spamtrap.pl to see the details of how all that works. -Eric

This probably isn't a secure long-term solution, of course. I'm not sure what would be, though.

So, if spammer sends to my mail server email with sender mylogin@mydomain.com and receiver hamtrap@mydomain.com, it can learn my spamassassin to accept his mail? I think it is the security hole. We must add checking for sender auth and mail sources before accept mail to hamtrap and spamtrap addresses.

I had this question too. Was any security ever added? One possibility would be for Spamassassin to sign its messages and then verify the forwarded message as having come from itself.
