getting local domain to get attached through sendmail ...

Morning all ...
I'm trying to get the committers mailing list to work, and the
"break" is in sendmail, as far as I can tell.  Basically, its taking
'locally posted messages' and not adding a domain to the back of it, so
that majordomo sees them as:

--== Error when connecting: Invalid address: "Marc G. Fournier" <scrappy>
You did not include a hostname as part of the address.at /usr/local/majordomo/bin/mj_queuerun line 470

I've tried adding 'FEATURE(`always_add_domain')' to my m4 config file, but
that doesn't appear to be helping, but figure it probably somethign really
obvious :(
