I would expect that any serious, large scale mail server (where through 
put from filesystem syncs may become a problem) the mail spools and 
other files would be on dedicated partitions to ensure that if other 
partitions filled (like /var/log for example) the mail service (and the 
user's mail) would not be affected.

That said, synchronizing the whole filesystem does seem a bit of a 
kludge at first blush.
