We recently updated to 15.7.6390 from 15.7.6347 and noticed that one of our Domain names was changed.
i.e. test.com to mail.test.com
The Domain folder is still set to test.com but our users are experiencing issues as some email is getting sent out as email@example.com and others as firstname.lastname@example.org .
Smartermail will not let us rename the domain through the actions dropdown menu. Is there something else we can try or has anyone else experienced this?
