Hello.
My SMTP server has to work relaying everyone, so I can't stop spam checking
the IP the message comes from.
I've though that all the e-mails that my server has to process must be sent
by people whose mail ends with "redys.com".
So I want that the SMPT server stops any e-mail whose user e-mail address
does not contain "redys.com".
I've been looking for spam filters, but they all use blocking lists (of well
know spammers) or IPs. Is there any program to check this?
I use tcpserver with qmail.
Thanks.
