Hello,
(Domains and public IPs censored)
i've added a new mail server behind a UTM appliance.
E-Mails from outside the Network will reach the new mail server, but when trying to send from the internal mail server, i get the error "<user@test-domain.tld>: mail for test-domain.tld loops back to myself"
My setup:
mail1.main-domain.tld (mail mail server) ext IP 200.0.0.1
mail2.main-domain.tld (new test mail server) ext IP 200.0.0.2
test-domain.tld has mail2.main-domain.tld as its MX.
Inbound goes through the UTM. Outbound goes directly out.
The UTM is setup in profile mode.
Global settings are for all Domains that are handled by mail1.main-domain.tld
I created a SMTP profile for domains that are handled by mail2.main-domain.tld.
So:
- Domains: test-domain.tld
- Routing: mail2.main-domain.tld (with internal ip)
- Everything else global settings.
- Profile is enabled
As far as i understand it, this should be everything that's necessary. But obviously i must miss something :D
