From: Wonky on 9 Jul 2010 07:53 I've got a LAN behind a firewall, on 192.168/16; the DMZ side of the firewall has address 192.168.10.20 (say), and the internet side has 123.4.56.78 (say). Someone sends a message to user@[123.4.56.78]; the filewall (with port 25 open) lets it through, but sendmail, not recognising the IP as either a local IP or local domain, rejects it, thinking it's a relay request. How do I convince sendmail that email sent to user@[123.4.56.78] should go to user(a)localhost? I've tried adding things like @[123.4.56.78] %1(a)localhost to files like /etc/mail/{virtus,mail}ertable, but it's still rejected. TIA
From: pirovano on 9 Jul 2010 08:11 sendmail doesn't like ip per default. it accepts names from /etc/hosts like root(a)localhost for local accounts. any other names, domains AND ip-addresses that are ment to be local you can put into local-host-names. regards, lorenzo pirovano

That worked (and I've been driving myself crazy trying to figure out how to do it!) Wonky

Have you tried to add [123.4.56.78] to sendmail's list of local email domains?
