What happens if there is a "SMTP Reverse DNS Mismatch Warning - Reverse DNS does not match SMTP Banner" on my domain name?
What happens if there is a "SMTP Reverse DNS Mismatch Warning - Reverse DNS does not match SMTP Banner" on my domain name?"
When I go to http://www.mxtoolbox.com and do an SMTP check of my company's external email address domain name, I get the results shown in the screenshot (see the screenshot).
I'm trying to figure out if this presents any problems or security issues with my domain (bayitnc.com) sending or receiving email.
Or might this cause issues with certain remote email servers where they won't accept emails from my domain because of this error?
Please let me know if any further info is needed.
