If we're talking about dovecot as the IMAP server in question, then,
yes, it can connect to a wide variety of databases for it's
authentication data.  It can also read from an arbitrary passwd(7)
format file -- not the same as the system passwd file.

On the scale the OP is working with, personally I'd not create 6000 unix
user accounts on the IMAP server: rather create a single account to own
all of the imap Maildirs and use a separate database of Mail user
accounts.  This and other configuration patterns are discussed in detail
on the Dovecot wiki as I recall.
