i am using mxtoolbox to verify my mail settings. When i changed SMTP banner on my edge server toReverse Banner Check for resolving ptr - the mxtoolbox said that"Warning - Does not support TLS".
It is cleas that if smtp banner does not match the hostname - TLS stop being supported (by some certificate issue maybe).
The main thing is how to make it work with new smtp banner on recieve connector.
Be real
