Hello,
I found that old treat, that has the same problem and the same messages I get while running SMTP-Test at mxtoolbox.com.

I have 2 servers running centos 7 and the actual whm-version. My servername is the same as my rdns - my hoster checked it and changed it some days before. So there shouldn't be any errors. But I get some and don't know how to solve them. The errors occure on both servers. They have the same configuration.

Thease are my problems:
SMTP Banner Check - Reverse DNS does not match SMTP Banner
SMTP TLS - Warning - Does not support TLS.
SMTP Transaction Time - 15.424 seconds - Not good! on Transaction Time

I hope you understand my problem; evan it is in poor english.

Regards
TH
