If it is not the www server, you can use one of the methods in FAQ 4.84

But it is trivial to augment your script that copies Mailman's aliases
for sendmail by adding something like
sed -r -e "s/^(.*):.*$/\1: \1 at mmhost.domain/" < /path/data/aliases > ...
plus the command(s) necessary to install those in NIS.
