This seems like it might be a problem.  A lot of the time when I get
"weird bounces" for messages for a mailing list, it isn't the list, but
somewhere down the line, which is bouncing because they either aren't
properly handling mailing lists, or something else (like in this
example given, failing to properly handle forwarding "bouncing onward"
sort of as the PINE parlance was used) list messages.

The message *to* you?  I don't think so.  Or it might be someone
sending from a server which somehow throws something into the header
that causes it to be bounced that the list manager doesn't properly
deal with?
