Um, just script up a snippet that send a mail through to a service
account (use telnet with expect, or perl or whatever... Make that
sending snippet a function/sub/procedure and let it take an argument
servername, then loop through the list of servers.... You know what to
do:-), then use an automated MUA in the same script (whatever you
need) to check that it is received within a reasonable time... Nail
within an expect script would be nice for that last bit ... How hard
can it be:-):-).
You'd have to keep an eye on reasonable timing, and think through how
to report errors...
Could probably be incorporated as a testscript into any monitoring
app... Or run from cron with some reasonable regularity.
Should be fairly easy to write up ... But I'm on vacation, so you do
it yourself;-).
