In line with this post:
… I am trying to set up Postfix to allow multiple domain names and SSLs for the incoming mail server.
The issue arises when I try testing a secondary domain with this service:
Unfortunately, it only defaults to my server’s main mail server’s SSL (mail.maindomain.com) and I would like it to switch to the appropriate one so the SSL certificate match-up test passes. What is considered best practice to do this with CyberPanel?
