I'm pretty much still a newbie to Linux. How can I, in this case in RH 7.3, check to be sure email is going out from a machine?
Simplest solution, requiring no technical knowledge whatsoever, is to send mail to one of your accounts which is on another system. For example, if you have a work email account, or a freemail account with someone like Yahoo!, try to send mail to that. If it arrives, things are working. Also send mail to a couple of your friends... if it arrives, things are working.
Where do I check/change parameters to direct all outgoing email from a RH 7.3 system to a specific SMTP server.
Using sendmail (the default SMTP daemon in 7.3), you have to change the SMART_HOST parameter in sendmail.mc. If I recall correctly, the correct format is:
define(SMART_HOST, `mail.myprovider.com')dnl
Please look at the top of the sendmail.mc file for instructions on how to make this modification take effect on your running server; you will need the sendmail-cf RPM package installed too.
