We have an SMTP server and wanted to configure sendmail on our linux boxes to use that server, very much like one would configure a UPS to use an SMTP server to send out alerts.

Is there a place in the configuration file in sendmail to tell it to send out email through a regular SMTP server?

Is there any way to do this? I've found information configuring to use a central hub, but we don't really need something that fancy...we just need to be able to send out alerts from our linux servers, and we would like to do it using our existing SMTP server.

Would smarthost be a good place to focus my efforts? Also, does anyone know how to configure the sendmail.cf on RHES? The info I've found through google indicates I need to utilize the m4 program using sendmail macros...but I can't find any macros that appear to be related to sendmail. Should they be there if sendmail is installed? Might I have forgotten to check to have them installed when building the system?

Thanks for any info.

Ah sendmail...it must be like people who grew up with Windows trying to deal with DOS commands...more oldschool than I am used to, but we have success.

I did modify the smarthost entry but I also needed to comment out the DAEMON_OPTIONS section as well so that it would not attempt to use itself for email. So our systems are now able to use the existing SMTP server.
