Can you double-check your mbox file?

With the most recent 2007 version of UW-IMAP, I've seen intermittent  
corruption of the first line of a mbox file (ie, the "From foo"  
header) which causes the mbox to be unreadable by most clients until  
it is fixed by hand.  It seems to be correlated with simultaneous  
write access by people who have a normal MUA and a second device like  
a smartphone (iPhone/Treo/BB).

I've seen just over a half-dozen of these since Jan...
