Hey List,
What is the most common solution to monitoring your postfix
mailservers?
I use Icinga and Munin. Is there a good integration to these?
That really depends on what you want to monitor about them. What are
they used for?
My primary use is to recieve emails for my domains. Next I want to
relay
general emails for a limited amount of authenticated users.
Then, I suppose the appropriate test would send test email messages
into the SMTP port, and raise an alert when some test message does
not reach its destination within a suitable time limit.
For example, periodically send email to
mailboxname+timest...@example.com,
and parse the "to=<mailboxname+timest...@example.com>" and
"status=delivered" out of the logfile record stream.

This kind of monitoring is usually done with a tool named "user". This
tool will phone you less than a minute after the system has a
malfunction.
Very drole, but not realistic.
The outages you want to detect are 3-hour queue buildups at 2 AM on a
Sunday due to a database problem, or outgoing SMTP failing.
On a busy server, such an outage could mean a server overload.
That is why you want to test the entire mail flow, not just queues or
incoming mail.
