How can I configure a Linux mail server?

How can I configure a Linux server as an email server? Also I need to set up an emailing programme on my own premises but route it through a dedicated root server in a server warehouse. The mail should go out from port 26.

1. Sorry I can't help you myself but register with www.justlinux.com and ask on the appropriate forum, someone is bound to be able to help.
2. A full complete answer to this is several pages long and would require a knowledge of your setup that I just don't have. Postfix is a fast, easy to configure, linux mail server that's available for most distributions. Redhat wrote a pretty good howto (in sources below). The important directive for directing all non-local mail out of your internal server to your dedicated server is relayhost. The line would look like relayhost = drs:26 (just replace drs with name or ip of your dedicated root server).
3. by default if linux is fully installed then sendmail comes by default configured on it . just make it start and also change Transfer smtp 25/tcp mail # Simple Mail Transfer smtp 25/udp mail # Simple Mail Transfer smtp 26/tcp mail # Simple Mail Transfer smtp 26/udp mail # Simple Mail in /etc/services file. then service sendmail restart on command prompt as root login and then execute your perl code . i am sure u wilget through. if not then buzz me at kshounish@yahoo.com kshounish
