All the email servers work except for one domain.

mail.domain.com

How do i check to see how come this mail server doesnt work..

is there a file i can try to fix.. ?

i can view the email in cpanel fine.. but when i check in outlook.

mail.domain.com

usenrmae: something@domain.com
and pass..

it says mail server error..

i have tried changing passwords and still no go.. tried rebooting pop server.. same problem..

try these steps

1) try to ping the mail.domain.com from remote location and see if you can ping, if you can not ping you have connection or dns problem

2) if you can ping try to connect to the server using telnet and see if you can connect to the server

telnet ip 25

if you can not connect make sure your smtp server (exim ) is running on the server.

3) now you need to login to the server using ssh and see if the exim is running and listening to the port 25

one way to see

netstat -nap | grep exim

4) if you get out something like

cp        0      0 0.0.0.0:465                 0.0.0.0:*                   LISTEN      26597/exim
tcp        0      0 0.0.0.0:25                  0.0.0.0:*                   LISTEN      26592/exim

which means exim is running and listening to the port 25 and 465

if you can connect and if the exim is running, please make sure your client ips is not blocked by firewall, if you are using linux and iptables you can do

iptables -nL | grep client_ip

5) if the ip does not get blocked by firewall, try to see what kind of error does the client has on the exim_mainlog file , you can check

exigrep emailaddress /var/log/exim_mainlog

that should give you more info,

hope that helps, if not seek professional admin help
