newbie problem

[Sujith Mathew]

Hello,

I am running linux redhat 8, without any SMTP server.Qpopper is running.

I dont know how to "map" domain name and pop3 user accounts to the QPOPPER. The DNS server is running fine.

This seems to be very newbie question. But i am literally stuck. Please help immediately.

Regards
