550-The mail server does not recognize ****@***** as a valid sender
Friends, I have an in-production server at aosystemsgroup.com and a test server that I just setup at aosystemsgroup.us
Having some issues with sending of email and receive the following
host aosystemsgroup.com [X.X.X.X]
SMTP error from remote mail server after RCPT TO::
550-Verification failed for
550-The mail server does not recognize email@domain.com as a valid sender.
550 Sender verify failed
I believe the occurrence here is that that cPanel installation at aosystemsgroup.com is rejecting the email for an improperly configured PTR record??
