I have a problem sending mail to mail lists from within gnuemacs .

First of all, everything worked fine when I was using regular sendmail on my
mail server, upon changing to sendmail.mx I get the following error
message when sending mail to any mailing list. This error only
occurs on sendmail clients.

Subject: returned mail for :include:/public/mailing-lists/admin.list
Status: RO

Mail error was: 550 <:include:/public/mailing-lists/admin.list>... Addressee unknown

The problem does not exist if I use sendmail on my mail server
instead of sendmail.mx. The mail server is also the yp master server,
using gnuemacs to send mail on the mail server to mailing lists 
works fine with either version of sendmail. 

/usr/lib/sendmail -v -bv admin shows the correct people in the
mailing list. Folks who use /usr/ucb/mail have no problems on any
machine using either version of sendmail.

Any help would be most appreciated.

Thanks,
