Can't send or receive emails!
Iv'e setup iRedMail on an Ubuntu 12.04 server.
But for some reason whenever I send a mail, it sends me another mail to me after some time saying “Undelivered Mail Returned To Sender”.
Moreover, I cant receive any emails either. Iv'e tried sending emails using Yahoo to my servers. And I do not even get the “Mail not sent email” either.
Thanks in Advance!
