sgichk_imap_inboxcount

This plugin is used to check the number of new messages in an IMAP mailbox. A certain database vendor's application is supposed to check an IMAP mailbox for new messages frequently (once a minute) and process them, but sometimes it just stops handling new email.

This plugin was both to detect this condition and to prove to the DBAs that just because bouncing cyrus caused the Ora.. (ahem) the Database Vendor's application to start processing new email again, didn't mean that the problem was with Cyrus. This plugin is able to show that IMAP is working fine, but email is accumulating in the INBOX (or in a specified mailbox).
