squirel mail and pop3 hang

[polo]

squirell mail reports this: Erorr Connection dropped by IMAP Server

Query Status "inbox" (message unseen recent)


pop3 says this:

Your mailbox is temporarily unavailable because another email message is being delivered to it or another mail application is accessing it. The server responded -ERR [In Use] Mailbox in use

error # 0x8004210E


What causes this and how is fixed/prevented?

Squirrelmail locks the mailbox when it's reading and if it fails to unlock, then pop3 wouldn't be able to access it.

I think squirrelmail uses flock() to prevent this, you might want to make sure it is working.
