Is it possible to use Nagios and an external mail server?
Meaning, connecting Nagios with an user and a password using imap/smtp to another mail server which is on a different server.
Looking forward to your reply.
PS: From what i`ve searched i could only see sendmail which has to be configured on the same machine as the Nagios is installed.[/quote]
Look at SSMTP, install on your nagios server - it is a simple mail relay agent and will relay any mail nagios sends to whatever SMTP server you configure it to use. (see -> http://www.nagiosbook.org/html/ch11s03.html
