Yes. Use "scp -p" if you use scp, preserves permissions and timestamps 
(actually not very important unless you're following up with rsync to 
check).

I'd expect rsync to be faster than scp, and personally I'd use "cd 
the-mailddir; tar cf 
- . | ssh remote 'cd remote-maildir; tar xf -'" which should be much 
  faster than either.

If the maildir is "active" I'd follow up with rsync afterwards, when it 
is idle, to catch any changes which may have occurred.

That will not be a problem. The hostname is just one of the values used 
to make a unique nonconflicting filename. It has no meaning afterwards.

And unnecessary.
