SmarterMail Server Monitor will monitor the current status of any number of SmarterMail 4.3 and later servers. It returns the current status of the POP, IMAP and SMTP services along with the Spool including the number of messages currently in the spool. This is pretty useful for anyone with more than a couple SmarterMail servers to keep track of.
