Topic: email server is rejecting genuine email addresses
I am running latest version of iredmail on one of my servers.. and i am getting complaints from my users that they are not receiving the emails they supposed to receive..
Upon checking the maillogs i found that the mail server is rejecting some genuine email addresses..
This is what /var/log/maillog has to say about the error..
