Since the sendmail/qpopper combination uses mbox a users mailbox is copied every time the mbox is accessed. If you have large mailboxes (e.g. no quota an users leave mail on server) this can produce a significant load. > > The owner of the company wants to go back to BSD, but I want to pursue > > Debian.

If you can make sure that the popper produces the load I'd suggest moving to Maildir for storage of the users mailboxes and perhaps Postfix with Courier Pop3d. > Apart from webmail that should be a trivial load.
