Hello List!
Im in desperate need for an SMTP proxy. Well, not just another proxy, it needs basically to do this:
- Listen on external interface, port 25
- If mail arrives, check the DESTINATION address of the delivered email and verify that against a list of valid destination addresses
- If the RCPT TO is valid* (in "allowed" list), then the proxy should relay the mail to an internal server
- If RCPT TO is not a valid* one (e.x. spam_victimXY@hotmail.com), then it should drop the mail and close the spammer's connection.
Is there such a program? --snip--
This is exactly what Obtuse SMTPD was designed to do. It is on the SuSE cd's in the "sec" section, labeled "smtpd" Check out www.obtuse.com for more info. I have it running happily sitting in front of both Postfix and Sendmail. I hear you cen even use qmail if you so desire as a backend. Cheers --- Nix - nix@susesecurity.com http://www.susesecurity.com
