I'd suggest using courier-imap or something else instead of qpopper. 
Afaik, qpopper supports only the mailbox format, which is slower and 
less secure than the maildir format used by modern pop3/imap servers. 
Courier-imap has a pop3 and an imap part, both of them have SSL support 
and are easily configurable. Your company migth benefit from running an 
imap server too. It has a bunch of advantages over pop3, so this might 
make your users feel more appreciated.
