This shouldn't be a problem if you run an IMAP server instead of using
sendmail/fetchmail.  With IMAP, you manage mailboxes on the server.
This puts more of a load on the server and network, but that's part of
the price you pay for centralized services.  I think there are a couple
of IMAP servers in the pkgsrc.  Recent versions of Netscape & IE support
IMAP as do a number of other mail readers (not as many as POP, though).
