Wow- thanks!
So, if I understand correctly, the issue is when the Listserv mails the
"approval" message to the netnews interface (using smtp), then the actual
"from" address in the distribution by netnews may not be the address that
the various newsservers have as the moderator's address, right? This is
what causes the sporadic approval- whether or not the proper host made the
mailing?
