I'm not aware of any problems with server mode and particular POP
clients. As I understand it, the only issue is whether any other
programs on the local system are altering the mailbox. If it's just
sendmail and qpopper, it should be OK. But it's entirely possible I've
missed something in the docs.
That said, you *can* enable server mode for specific users.
We have a similar problem where we couldn't turn server mode on for
everyone because some people use webmail and others use POP. However,
our "problem" users -- the ones with the biggest mailboxes who leave
mail on the server and check the most frequently -- only used POP.
We put the following in our qpopper.config:
set spool-options = true
Then we set up .username.qpopper-options files in our spool directory
containing:
set server-mode = true
The server used to have major I/O delays whenever one of these users
connected. After I set this up for just 5 accounts, the problem cleared
up completely.
