SMTP relay to internal Notes domains

I got a configuration issue which I can’t resolve. I’ve searched through the forum but the issue never matches my situation exactly.

I have 1 server in the DMZ doing SMTP relay and several Notes domains behind it. The remote directories are available at the SMTP relay via directory assistance and test mails are accepted by the SMTP relay.

However, a mail for someone@domainB enters the relay server and leaves the server as someone/certificate%notesdomain@domain which is not accepted by the internal servers. The global domain contains all internal ‘internet’ domains as well as the domino domains to make sure the conversion works as expected. I used foreign SMTP domains to route to the backend Notes domains via SMTP. When using SMTP connection docs, I get maximum hop count exceeded.

Anyone has a similar setup? What I want is:

  1. mail enters on SMTP

  2. basic relay checks on relay

  3. basic recipient checks in all address books on relay

  4. for Domino domain B, C, … , forward to specific SMTP server

tx,

Stijn.
