If you mean stuff that verify wether a process is running, there are lots of
that, and it ain't difficult to write one of your own either. Search google

Well, if you are going to test the mail service itself, then you'll probably
need to write one of your own. My suggestion:
1. Fire up an email to your esmtp server in a cronjob
2. Said email needs to arrive to a test user in cyrus, which has a
sieve script that redirects it to another address
3. Said another address is a postfix/exim/sendmail pipe that calls
a watchdog pat script.
There are other ways. Such as connecting to a mailbox using IMAP
and verifying if the tracer email got there, delete and expunge it, and so
