Well we are getting closer. I am now able to telnet to the server. I tried to send mail to the server but kicked off every time i try to do the subject line.

I have the .procmailrc file set up as per the xymon man page, still not sure if the "Mailbox" is a directory or file. and the directory structure of the xymon home directory looks like this.

drwxr-xr-x.  2 xymon xymon  4096 Oct  2 11:02 Mailbox
-rw-r--r--.  1 xymon xymon     0 Oct  1 12:15 procmail.log
-rwxr-xr-x.  1 xymon xymon   124 Oct  2 11:04 .procmailrc

This feature is one of the most important to the company I work for and have been trying to get it to work for a couple of days now. We even added an MX record for the server so mail can be delivered to it directly. Telnet works locally and remote.

Any recommendations would be greatly appreciated, you have all been a huge help so far and this monitoring tool has done wonders for this company.

I am using Centos 6.2

By default Centos (aka Red Hat) v6 boxes run postfix (rather than Sendmail).

During my install I do not remember installing anything as the mail transport, but the alerting was working right out of the box from day one.

Initially, postfix is configured so it won't accept SMTP connections from off the box.  So outbound emails will get sent OK, but incoming emails will not get delivered to the Xymon server.

Test this by attempting to telnet to the Xymon server on port 25 from another device, such as a Windows PC, with "telnet xymon.server.name<http://xymon.server.name> 25".  If you get a "connection refused" or similar message, than you need to reconfigure Postfix to accept remote connections.

I followed the man page for the mailack and created everything as per the instructions, but I am not even sure the mail is reaching the server at this point.

Probably not.  Have a look at the "STANDARD_CONFIGURATION_README" file that came with Postfix for instructions on setting things up, particularly the "Postfix on a local network" section.
