When I look in the file, I don't see anything unusual. There's not much info on the Internet about this problem. The only thing I found mentioned blank lines in the file. So, I tested and found that I'm able to get mail on other accounts regardless of whether there are blank lines in between messages.
Generally the problem is that the file doesn't start with "From ". The "blank lines" are before these 5 characters. I've seen this issue come up periodically in one user's Mozilla Trash folder. Nothing writes to that folder except her IMAP client, and she runs only one instance. (dovecot-0.99.13-4.FC2) Each time, the problem has been a few thousand ASCII NUL's at the beginning of the file. I delete those and the system works fine for a few more weeks. At some point I'll update to the 1.0 branch, which has different mbox code.
