Hello,
I paid for CWP support to fix my postfix and mail server so that I wasn't getting invalid certificates. They advised all they did was add my server to the /etc/hosts in an entry and rebuild my email server. After restoring a snapshot due to other reasons (where I didn't mess with postfix at all) I am no longer able to connect to mail servers and send email. I also had tried what they said they did probably 20 times no joke and this didn't fix the issue which is why I paid for support! Has anyone ran into this or no SASL authentication mechanisms? What did you do to fix it? Any tips? Appreciate anyone's help!
