i can't receive mail to a particular mail id, the log shows like this
SMTP error from remote mail server after RCPT TO:<[email protected]>: 450 4.7.1 <mailstore07.ab2bz.com>: Helo command rejected: Host not found
these both mail ids are unknown, how can i resolve this. actually there was an attack towards this mail id and i changed the password to a strong one.
