Few months ago, I did setup a mail server and I faced a problem.
Simply, I could receive emails sent to email@example.com
but I couldn't get them when they are pointed to firstname.lastname@example.org
After long googling (several days) I could solve that problem.
(Then why you are here?)
Alright, the same problem is going on, but on another setup, another box.
And, to be honest, I'd like to be pointed to where should I look to solve this out, so I can solve it quickly if I faced it any time in the future.
====== The System
- Slackware - current.
And question is welcome
Thanks in advance..
