Are you just trying to add a 'mail' attribute to the group entry,
or do you want the MTA (mail system) to use LDAP data to expand
the mailing list?

Adding the mail attribute is quite simple: define an AUXILIARY object
class that permits the attribute, add that to the group entries, and
you can then add the mail attribute.

Doing group-based mail expansion takes more work, and really depends
on what MTA you are using. You would need to configure the MTA to
recognise the groups as valid list-expansion targets. It would then
read the group and fetch the mail attribute from each member entry to
construct the list. If the MTA cannot do this two-stage process itself,
you could consider using the dynlist overlay in slapd to collect
the members' mail addresses into the group entry itself.
