Hi all,

I know this subject was discussed sometime back and I did see a reply
suggesting the use of Sendmail capability to filter out duplecate address.
So I tired it but with out success.
May be someone can point me on what I am doing wrong here.

I am maintaing MJ with about 120 lists in my location.
Recently I was requested to create a list that contains multiple lists
in it(sort of nested lists). Problem began as many people in the sub-lists
are subscribed in more than one lists. Whenever a mail is sent out through
this "parent" list, people subscribed in two lists will receive two copies
and subscribed in three will get three copies and so on.

I attemted to utilize the :include: in the /etc/aliases so the alias for
parent list would look something like below;

owner-p_list:        p_list-owner
p_list:              :include:/usr/local/majordomo/list/p_list
p_list-owner:        owner
p_list-approval:     p_list-owner
p_list-outgoing:     :include:/usr/local/majordomo/lists/p_list
owner-p_list-outgoing:       p_list-owner
p_list-request:      "|/usr/local/majordomo/wrapper request-answer p_list"
owner-p_list-request: p_list-owner
#

where /usr/local/majordomo/list/p_list is the file that contains the
list of sub-lists.

While a sub-list alias would look something like below;

owner-s_list:        s_list-owner
s_list:              "|/usr/local/majordomo/wrapper resend -p bulk -M 10000 -R
 -l s_list -f s_list-owner -h mdomo.isi.com -s s_list-outgoing"
s_list-owner:        owner
s_list-approval:     s_list-owner
s_list-outgoing:     :include:/usr/local/majordomo/lists/s_list
owner-s_list-outgoing:       s_list-owner
s_list-request:      "|/usr/local/majordomo/wrapper request-answer s_list"
owner-s_list-request: s_list-owner

When a mail is sent out to the parent list(p_list) with this configuration,
I would get following error from maillog;
