I'm trying to set up sendmail on a server behind a firewall. It can only resolve DNS within the firewall. I want it to deliver mail to addresses within the firewall (all one domain) and pass on mail for the rest of the world to a gateway which does have external DNS.
The problem is that while local delivery is fine, mail to the Internet always bounces with the error "DSN: Host not found". This makes sense, my server has no external DNS, so I'm looking for a way to disable Sendmails' use of DNS. The docs suggest removing dns from /etc/nsswitch.conf but this isn't an option as this would disable DNS for all services on that system. There is a FEATURE(nodns) but that according to the docs is a no-op. Then I read about mailertables. This looks like it could do the trick except it doesn't :-( Here's what mine looks like. localhost local:localhost .mycompany.com procmail:localhost . relay:mail.mycompany.com What went wrong? Is this not the right way to achieve my objective? -- Jaldhar H. Vyas <[EMAIL PROTECTED]>
