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

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 25".
 If you get a "connection refused" or similar message, than you need to
reconfigure Postfix to accept remote connections.

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.
