I made a dirty change in drv_imap.c to skip messages with lines of more 
than 10000 bytes and voila ... no more problems with exchange online ...

Anyway I did it wrong, because mbsync doesn't retry those messages when 
I use ReNew, there's no entry in the sync file, but that was a test
I'm parsing the message in imap_fetch_msg_p2() and altering response to 
RESP_NO, the message is just ignored as if it wasn't there

I'm planning to do it the right way and contribute a patch, but I'm no C 
coder and the result may be ugly
