im trying to setup a mail server.
i have installed ubuntu server along with webmin. I have changed the DNS to point the server. But am unable to send or receive mail. If i try to send mail it keeps saying tis going from user at localhost instead of domain.
Also no mail is arriving. I have installed postfix but not sure if i am configering it correctly or if its BIND DNS and what i need to be putting in here
can anyone help me
