OK this is not another Perl and Apache installation or config problem. Everything works fine, to a point. Here is where the problem is;

Everything used to be fine when we had one server hosting websites and being a mail server. Now we got 2 servers. One to host the sites, the other one just for mail. When we had one server doing everything the perl scrips would execute the forms and email them to me when the person would fill them out online.

NOW, My Apache hosts the websites no problem on "server1". I installed Perl on "server1" as well to run my scripts and forms. The forms execute great, no errors, no problems. My mail server "server2" is on a different server then my website server and the mail server works well, I send and receive emails no problem. So we have 2 servers doing two different things. The problem is that I dont get the forms mailed to me now.

I think this is because the webserver "server1" is trying to use itself to send the email but it needs to use the mailserver "server2" to send the mail out. This was not a problem before because the mail and web servers was one machine and now its two different machines.

I am sure there is a configuration for this somewhere but where? This has to do something with "server1" the web/perl machine but what config files do I need to look at? Is it the Apache config, the perl config, the mail(not used) config?

This has nothing to do with the apache/perl config. What you should be looking at the the actual code of the websites that are sending the mail and see how the sending part is implemented.

If it points to an smtp server then you can just modify the code to point to your mail server, if the sending is being done using the sendmail command you need to setup a light server to actually deliver these messages to your mail server.

Yes we have the sendmail command. How do I set up a light server to actually deliver these messages to my mail server? I never heard of a light mail server. Any place I can look that up on how to do that?

By Light i mean the MTA will only deliver mail submitted by that host, it will not accept any connections from the network.

Usually out of the box sendmail is capable of doing this, you may just need to configure masquerading if you don't want the host part in the email address.

OK, like always it was a simple problem. As most IT Techs will tell you. "Have you tried turning it OFF and ON."
Not that easy but close. Even though I was using sendmail with my cgi I didnt have sendmail installed on the website host server. A simple 'sudo apt-get install sendmail' and the problem was fixed.
