Hi, Spammers are often using unavailable Mailboxes and when the main server ( not custom domain ) receives this kind of spam he refuses with the following answer "550 Mailbox unavailable" : that's correct!
But I have a problem with backup MX using custom domains. If this spam is directly sent to the backup MX ( custom domain with "smtprelay") the mail is accepted and relaying to the main MX server. In this case, the backup MX receives "550 error message", the postmaster too...etc. Too many transfert, bandwith and CPU charge for nothing. I tried many solution but i didn't find the right way to stop this unusefull process. Has anyone found a solution or any idea to reduce process ?
