Sorry, I meant the raw mailboxes used by Tbird on their own machines. 
Because they were originally using Outlook, many people inadvertently 
saved their mail on their local machines not on the server. We've moved 
them to Tbird which does a good job of importing the local mail from 
Outlook, but now we can't move the mailboxes to the server because they 
contain barenewlines. So short of patching Cyrus to accept these 
messages (which I'll only do as a last resort), I was wondering if 
anybody had a nice little piece of perl that I could let loose on these 
mailboxes to scrub the bare newlines from them.

Thanks,
Z
