I've read a few people discussing the possibilities of forwarding emails 
based on the groupofnames attribute in an ldap group.  I've read that 
the main way of doing mailing list groups is to add multiple instances 
of 'mailForwardingAddress' to a qmailUser with the mail set to the group 
email address. 

The only problem I have with this is that there are now two email 
addresses to manage in my ldap directory.  This is not necessarily a 
problem, but it will cause a few conflicts every once in a while.  Other 
than those few posts, I haven't found too much information with regards 
to this situation.
   

How about setting up an ezmlm mailing list and including those couple of
users in it for members.  Have it set so that only you can add people to
this group.
This is a possibility, but that seems like it'd have the same problems 
of email addresses changing.  Since their working email address will 
always be in the ldap 'mail' attribute of their user dn, and an ldap 
groupofnames member specifies only the dn.  By getting the member list 
from the ldap directory, and then getting their primary 'mail' address 
specified in their dn, I'd always have a current list of email addresses 
for group members. 

 

Here is the main problem.  Since I'm not able to send the email 
addresses back for qmail to forward the message off nicely.  How should 
I look at resending this message?  Most of the qmail-command examples I 
see are simply to either send a new message back to original 
sender(vacation) or to pass a value back to qmail, so that it knows to 
reject/accept the message.
   

I'm not sure what you're asking here.  Are you trying to have users send
out email with that group email address listed in the From?  That's
primarily a mail client issue.

The user will send an email to say [EMAIL PROTECTED]  This address maps to 
a ldap entry with objectclass values of 'qmailUser', and 
'groupOfNames'.  Having deliveryProgramPath set to 
'/location/grpemail.pl [EMAIL PROTECTED]', and qmailDotMode set to 
'ldapwithprog'.  The grpemail.pl will search the ldap directory for the 
email addresses the email group [EMAIL PROTECTED] is mapped to.  This works 
great, but I don't know what to do with the addresses given back by 
grpemail.pl.  I was wondering if I have to use some sort of internal 
perl mail spool type library, or if I can somehow give these addresses 
back to qmail to forward the email grpemail.pl has received.

Or to find out if I'm just misguided, and there's an easier way to 
forward an incoming email to [EMAIL PROTECTED] to all the members 
specified in the by the 'member' field of the groupOfNames objectClass.
