Importing MBOX-formatted mailboxes into Cyrus?

I am trying to use the Thunderbird mail client to move POP3 messages  
from some Mac OS X clients to Cyrus running on Mac OS X 10.4.

I have created mbox files with a utility for Mac OS X called "emlx to  
mbox Converter" which converts file used by Apple Mail 2 to mbox format.

I was able to get the mbox messages into Thunderbird's local folders,  
but when I tried to move messages from there to IMAP I received the  
message "The mail server responded: Message contains invalid header."

Is there a log file that would give me more specific information? Any  
suggestions for how to troubleshoot this?

Regards, Phillip
