This happens only when this is 1st domain

Howdy -- hmm, can you paste in the contents of your /etc/postfix/main.cf file on that server? That would help us understand what isn't working there. Thanks!

I am having the same issue. I have followed the instructions to create a relay at https://www.virtualmin.com/documentation/id%2Cmail_relaying_with_virtualmin - when I enable the relay on the my first domain I get the same error.

I have removed the last line to return function to virtualmin and to start postfix again. Any help would be great

What I would suggest, is to make the last line read:
relay_domains = example.comThe rest of that line shouldn't be necessary.

Thanks andreychek this solution fixes the issue and the relay seems to work properly. The problem I have now is that if you enable the feature "Relay mail for domain?" for the virtual host it generates this automatically so each time I would need to create a new domain that has an external mail server this becomes an issue. Maybe there is a long-term solution for this?
UPDATE - Actually it creates the proper relay on all domains now -- example realy_domain = (adjusted domain.com), new.domain.com, domain2.com ...etc
