We have three domains hosted on a mailenable server.
However, except for one domain, the other two domains give the following error when I check with MXtoolbox for emailserver test.
"Reverse DNS does not match SMTP Banner"
So we have www.domain1.com and www.domain2.com and www.domain3.com. The SMTP server is configured for www.domain1.com. When we check domain2.com and domain3.com using mxtoolbox, test mail server, it gives the above error.
How do we solve this ?
