I'm fairly sure that's correct. MTAs generally don't care if the MX domain doesn't match the certificate on port 25. But MUAs generally do care if the hostname they are configured to connect to doesn't match the certificate on whatever ports they connect

yes for MUA connections I did setup the correct certs. I didn't use the mailinabox, just implementing all by hand.
