Just a guess: those processes could be the result IMAP clients making
use of the IMAP IDLE extension ("push mail").

Thunderbird, by default, opens up to five connections to the IMAP server
and keeps them open - thus you see five IMAP processes for each user.

Why would you want to kill those processes - do they cause any problems?
