I was wondering if anyone can give me a hand with this.

Current Setup::
I have a Fedora Core2 server setup and it is running with Nagios on our internal network, I am currently relaying mail (with sendmail) through our internal mail server to inform our Help Desk of any failures.

Problem is if the mail server goes down we don't get informed.

::Perfered Setup::
I would like the Fedora server using sendmail configured to email out without using a relay, it does not need to receive any email just be able to send out email, this way if our mailserver goes down we still receive the alerts.

How is this done, is it possible to setup sendmail without a relay or do I need a seperate application?

Probably in your /etc/mail/sendmail.mc file there is

dnl # Uncomment and edit the following line if your outgoing mail needs to
dnl # be sent out through an external mail server:
dnl #
dnl define(`SMART_HOST',`smtp.your.provider')

This is my sendmail.mc, yours probably has 'define(`SMART_HOST',`smtp.your.provider') without the dnl, add dnl to the beggining of the line it should then bypass your internal server

Don't forget this file has to be remade instuctions should be at the top of your sendmail.mc file

Also stop and start Sendmail for the new configuration to take effect

That is what I am currently doing, I am realying through a mail server. I don't want to relay at all, I want the linuxserver to act as the email server.

Sorry perhaps I misunderstood your question or just did'nt explain it very well

Pete

My apologizes I thought I did explain that I did not want to relay.

Sorry ChaChi but I've really got to give this one more try

Your sendmail.mc currently looks like this
define(`SMART_HOST',`smtp.your.provider')

Make it look like this
dnl define(`SMART_HOST',`smtp.your.provider')

Pete I think you are still not understanding.

This is what you are refering to.
This is only used if you are sending mail through an external server, I do not want to send mail thourgh a seperate server (which is what relay means) I want the LINUXSERVER to be the mail server and I want the ability to send mail out of LINUXSERVER without configuring RELAYING...

I hope this is clear enough for you and everyone else.
