Because the clients do so.

Yeah. If the blue traffic sign with the bicycle on it tags the left road, 
many bicycles will choose this way, but some still choose the right road 
with the blue traffic sign with the pedestrian on it.

The "\Sent" is a hint for client, which way to go. Either force your users 
to use another client, re-configure their client manuelly, or - sometimes 
- - the mail client needs to refresh its configuration.

Yes. What kind of subdir do you expect?
