Courier-IMAP / XINETD Keeps Restarting

KrazyBob

Regular Pleskian
I have a server that courier-imap / xinetd keeps restarting on, seemoingly for no reason. The onlything I note when I check is what appears to be a rogue Blackberry that is attempting to access IMAP on all web sites. It shows up as a popuser on port 143 all day and night. Their abuse department has yet to reply to three complaints. The same with MyCingular. All day and night; one web site to the next, IMAP.

But even after blocking the IP's I still get annoyed by constant Plesk alerts that the service is down. When I go to check Plesk has already restarted the service.

Here are the messages:
