Thanks much guys, you've given me direction. I seem to only have access to
the /home directory on the server and the trouble ticket guys are saying
they can't make changes.. so pursuing those avenues. This is above my pay
grade as far as understanding MTAs, but can edit files via shell as I have
run linux servers in the past. The list in question has about 2100
subscribers - it is a community announcements and trade list - and I'm the
admin but don't make any money off it - just a volunteer.

The "simpler" was in a line from a quote from the tech support guys at the
host company. I see I didn't make that clear. I've asked them for more
clear directions on accessing the mm_cfg file or at least to verify the
current settings in it, as I don't seem to have permissions for the /etc
thx, JD
