It appears that:
1. When I change the mime_driver and say inline=true, the already seen 
mails are still with the old value, so no links. That's probably a cache 
problem, but not annoying.
2. For the bad msoffice detection, it appears that it was a problem with 
mime_magic under linux debian etch. Installing the last mime_magic from 
lenny solved that problem.
