Mail Server Issue

[pbaker]

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

i have set a mail server i can send mail from my server and it arrives at the other end to external addresses. however if i try to send mail to the server i get a bounce back saying domain not hosted here.

what have i configured wrong. I have contacted my isp and they say its nothign to do with them its down to my server settings.

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

The following message to <mail@mydomain.co.uk
5.1.0 - Unknown address error 550-'This domain is not hosted here'.

Im using webmin as well i have posted my records here is there someting missing

i am trying to setup a linux mail server. I can send mail out locally from the server but am unable to send anything to it if i do i get the error back saying

The following message to <fmasterstcoldtouch24.co.uk> was undeliverable.
The reason for the problem:
5.1.0 - Unknown address error 550-'This domain is not hosted here'

this is the zone i have created via webmin but guess there is someting missing from here. Can anyone help?. i have replaced my ip address with the word my ip just to be on the safe side in this post.

I'm not an expert on mail server. I think you need something like dovecot to receive mails.

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.

on my setup there isnt a /etc/mail/local-host-names but i have pasted the netstats for you to look at
