Hi everybody,
I've set up ASSP and have been running it for ages now, but I am suddenly being listed as an open relay. The way I've figured it out now is that the problem is that ASSP accepts messages which my MTA then rejects. The problem is that I have some relaying addresses on my MTA, which doesn't allow me to turn on domain checking on ASSP. What I mean is this: I have an address [email protected]. Mails to this address are forwarded to u...@external_domain1.com by my MTA (Exchange 2003). Now if somebody external to my organization (say u...@external_domain2.com) sends a message to [email protected], all ASSP sees is a message going from u...@external_domain1.com to u...@external_domain2.com, so it won't permit my MTA to send this message out if I have domain checking active. If I deactivate domain checking, it works, but my server is being listed as an open relay, because invalid messages are accepted by ASSP and only later rejected by my MTA. So technically my setup is not an open relay, but open relay checkers may believe it is... Does anybody know a solution to this conundrum? Stefan. PS: My setup is (Port numbers changed): Internet - 25 - ASSP - 125 - Exchange - 225 - ASSP - 325 - Mercury/32 (as a smarthost) - Internet ------------------------------------------------------------------------------ Come build with us!
