LDAP group lists in postfix

Hi List,

I'm working on a major email server revamp. We're moving from a sendmail
UW-IMAP mbox local accounts setup to a postfix dovecot maildir virtual
account setup. We're already authenticating users with LDAP, but I'd like to
move anything I can to LDAP. I *think* I've got a pretty good idea how I'm
going to handle most of it, but I'm not sure yet how to handle our group
lists.  The way we have it set up - well it sucks.  But more to the point,
we have a set of files that contain lists of email addresses for a certain
group, department, whatever. Then /etc/aliases has an include entry for the
file. So, it works, but it's painful to maintain. Another requirement we
have is that we have certain groups we keep "locked" - we comment them out
in the aliases file until someone requests a specific group, let them send,
and re-comment it out so that not just anyone can email the whole
organization. Again, this works, but there's got to be a better way to
handle this. I'd like to make it so certain people can always email those
addresses, but everyone else would need permission.

Does anyone have some insights they could share on how to move this
functionality into LDAP with postfix?

Thanks!

Del
