Would using passwd-file as your passwd database be acceptable? The 
authentication won't go via PAM, if that is what are looking for, but if you 
point passwd-file at a copy of the system passwd file you should be able to 
run an unmodified dovecot and use a single password for your services. Then 
just write a very short script to:

o filter out only the mail accounts from your master passwd, joe, bob, mary.
o rewrite the entries into user at domain:password:::::etc format.

Then either run this every so often, or use the 'unix passwd sync' feature of 
samba to make sure it is synchronised when a user changes their password from 
Windows.
