This seems most promising, but I'm not sure how to put it in.  I found
"Filter"  under access control in the configuration wizard, and this
information:
"If "Filter= Also..." is specified, your filter is used in addition to the
standard LISTSERV filter. This is useful to register additional looping
mailers, to prevent users behind broken gateways from subscribing until the
problem is addressed, or to ban anonymous posters."
It seems like "looping mailers" is the problem, but the document also
suggest Loopcheck=full is on as a default.
Could you elaborate on how and where to put int the content filter?  And
where the messages following it part of the filter, on the product of the
filter?

That way, when the individual returns, and attempts to send a nastygram to
the list, it won't be distributed.

you can establish with your co-list owners so that when you are not there,
and they do a QUERY listname FOR poster, that combo of SET options is the
tell-tale sign of previous delivery problems.
