email notification

[epsone]

Hi

I have a problem i can't receive notification by email (when one server or service down that i do it manualy just for the test) .

I installed mailx and postfix under Fedora10 .

Now i think the problem is in the /etc/postfix/main.cf because i think i should modify just this three parametre if i m right .

myhostname

myhostname = ServerNagios.domaine.com

mydestination

mydestination = $myhostname, ServerNagios.domaine.com , localhost.$mydomain, localhost

relayhost

#relayhost = $mydomain
#relayhost = [gateway.my.domain]
#relayhost = [mailserver.isp.tld]
#relayhost = uucphost
#relayhost = [an.ip.add.ress]

Please can you help me to solve this big problme ,I will be thankful.

many thanks

Ok, from the look of that, you're hoping to mail direct out to the recipients. Does your ISP allow that? Or are they expecting you to relay all mail through their own SMTP server?

I don't think so , that i need That is, my server does not store the mailboxes of users, it only transmits messages to the SMTP server, which manages the boxes.

Have you specified the SMTP server?

Ok. The way you need to set it up is as such:

1. Nagios server sends messages to
2. Local postfix server which sends messages to
3. Your SMTP server.

An example of how to set up Postfix to relay mail through an SMTP server can be found here:

Send Mail Postfix through Gmail’s SMTP on a Ubuntu LTS Server

This is sending via a TLS secured SMTP server, with authentication. You may need to alter accordingly if you don't require a secure connection or authentication.

execuse me i can use our exchange server so nagios server sends messages to exchange server ???

thank you

You can, but you still need to set up postfix to connect to the exchange SMTP server, as with that link I provided.

Yes, to mail via another SMTP server is more complicated - especially a server like Exchange, which will require authentication and TLS. There's not much more I can do, as that link covers pretty much everything...
