Re: [monit] Alerts not being triggered

[Bruce Reed]

The strace uncovered my problem and it was with a mail alias, so thanks for
the tip! 

It would be nice to have more verbose logging by monit to log email events.
Had I seen those in the log I would have known it at least sent the message
and the problem was with the address I had used. On the other hand, I should
have combed my mailserver logs to see if a message had been received for the
address I specified.
