I'm with Gjermund. Anything more than three levels deep is probably
excessive. I tend to use the letters of the user as sub-dirs, so
"john" ends up in /var/mail/j/o/john, or perhaps /var/mail/j/o/h/john,
which gives 26^3 directories. Assuming an even distribution (which
it's not), a server supporting 64K users would end up with just 3
entries per sub-dir!
In any event, any reasonable distribution alg will work and anything
more that 3 directory levels is probably excessive for all but the
most pathological of situations.
Regards.
