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. 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

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).
