While playing around with various list config settings, I added
a Filter_Also='user@somehost' entry to the go.user file.

('user@somehost') is used here to replace the actual email address.)

I expected mail from this address to be rejected, whether sent
to a list, or to the server, and it was. But the message I
got by sending the command "list" to the server was a bit odd:

"
The enclosed message, found in the LISTSERV mailbox and shown
under the spool ID 0020 in the  system log, has been identified
as  a possible delivery error notice for the
following reason: mail origin seems to be a mailer.
"


???


Mail sent to a list did produce an error message
that let me know the address was filtered.
