>My POP server stopped working at midnight. My client (Eudora) can't connect to it, and the monitor window occasionally shows "System Error -39". The log reads, for example:

The mailbox file is corrupted. A -39 error is an end-of-file error, that is, the file system read operation reached the end of the file prematurely. There should be more file there but there isn't.

See? Reading the mailbox file failed. I'm betting that deliveries to this account fail as well, yes?

Best course is to probably delete and recreate the account.
