Reverse DNS does not match SMTP Banner - Messaging Gateway
Hi everyone, I had a problem with Messaging Gateway. When I run the SMTP scanner on mxtoolbox.com this result came up.
OK - 190.12.x.x resolves to mx.xxxx.com.ar
Warning - Reverse DNS does not match SMTP Banner
0 seconds - Good on Connection time
Not an open relay.
1.123 seconds - Good on Transaction time
What can I do from Messaging Gateway to solve this situation?
THX to all.
