    mail server problem


    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

    I couldn't do it either. But salvation is at hand. pop axigen in google.

    They have several, and they work.. There is a totally free one, but only five mail boxes.

    the others you can get a yearly key
    hope that helps ya

    Have you set up your MX record correctly? Maybe a firewall is getting in the way? What is the error message you are getting?

    I'm not an expert on mail server. I think you need something like dovecot to receive mails.
    This guide might be useful Quick HOWTO : Ch21 : Configuring Linux Mail Servers - Linux Home Networking

    Hi,

    With mail server configuration, as far as I recollect, you need to mention a list of domain that the server is responsible for accepting mails. In the file /etc/mail/local-host-names enter the FQDN of the server as well as just the domain name.
    Also whats the output of netstat -atn? Does it show that its accepting connection for port 25 only on 127.0.0.1 or is it 0.0.0.0.

    --Syd
