Re: adding an outgoing-only smtp server?
Hi Dave, I just wanted to thank you for giving me clarity (which also set off a number of chain-reactions in my head :). Best regards, jamie #-#-#-#-#-#-#-# -- If somebody can help create a search engine for my room, I will call them a Saint... GUI == Graphical User Interference

A clever remote server might reverse lookup host2's IP address, yes. I think it'd be sufficient to set control/helohost to host2's FQDN. I don't know of any MTA's that check the return path hostname against the HELO hostname. >Where-as, if host2 was listed also as an MX, qmail-smtpd is >not running on it so won't the messages get deferred/bounced >if any incoming connections were attempted? Yes, they would. -Dave

Configure host2 to pretend to be either the MX > or host1 (e.g., in control/me replace host2 with host1). Wow, that simple? Thank you for your input. (now I need to find myself another box :) OTOH, this is where I am confused still: If I'm correct, I don't need an MX entry for host2 in the dns records right? (since it shouldn't respond to incoming messages) But if host2 sends email out as host1 without host2 listed as an MX, wouldn't the IP address or "return-path" resolve back to an "unknown" host, or get denied from the remote smtp server? Where-as, if host2 was listed also as an MX, qmail-smtpd is not running on it so won't the messages get deferred/bounced if any incoming connections were attempted? (sorry for this confusion) Thanks again. cheers, jamie #-#-#-#-#-#-#-# -- If somebody can help create a search engine for my room, I will call them a Saint... GUI == Graphical User Interference

OK, so where are you stuck? Install qmail on host1 and host2, but skip qmail-smtpd on host2. Configure host2 to pretend to be either the MX or host1 (e.g., in control/me replace host2 with host1). -Dave
