I know, but I mean Cyrus with its env and Qpopper with other users.

I have:
  + on server A:
    - Cyrus v2.2.12 (IMAP) (+ sendmail) with 7531 users
    - authentication via sasl (sasldb)
    - domains a1.domain, a2.domain, ...
  + on server B:
    - Qpopper (POP) with about 200 users
    - auth via /etc/passwd
    - domain b1.domain, b2.domain

I'd like to move pop users to server A.

I have problems to enable Cyrus pop because I don't know their passwords 
and I don't want to change or ask to users (for several reasons) for them.

I'd like to install Qpopper on server A and move all the mailbox 
(standard, one file per user) without stop pop service.

My problem is: how can I manage incoming email ? How can sendmail to 
route email to Cyrus (mailer cyrusv2) or to standard local mail (for pop 
users) ? Some tricks on ? mailertable ?
