POP3 Test
The MFM server connects to your mail
server using POP3 to check that the sent message has been received. If the
monitoring server can connect to the POP3 server it will indicate that the test
is successful, it will then wait another minute and a half and start over. If
the server is not found by the monitoring server, it will wait a minute and a
half and then it will check for the server again, if the server is still not
found by the monitoring server it will repeat the check until the server is
found or the failed threshold is reached. If the failed threshold is reached,
the monitoring server reports the failed POP3 service.
