[PERDITION-USERS] MySQL

I've just setup perdition and MySQL and I've got it sort of working... but I want to split some users here and some there. So I want to have: some1(a)user.com to server1: imap some1(a)user.com to server2: pop some2(a)user.com to server3: imap some2(a)user.com to server4: pop The MySQL config has three fields: user, port, hostname, I dont seem to be able to see or understand how to make some users go to different place depending on the connection type. ie: imap connections to this server on that port and pop to this on that port... can anyone explain?
