I've seen POP3 work and not work in different situations.  The
University of Waterloo had Endymion Mailman set up for the longest time
on their mail server to access mail through POP, and it worked well
enough for most students.  I tried doing the same with an ICAN account
once upon a year with a number of clients to little success.

As usual, this is a tradeoff.  The design of maildir is such that file
locking is no longer an issue, so (almost) any screwup of the mailbox
won't result in lost email.  Yes there are more files, but each file
contains less information, is less critical, and has less activity.  It
comes down to a design decision:  one big file that has everything, or
lots of little files, each of which are non-critical?
