Depends on the exact nature of the error: if the mail was delivered and
returned. then hopefully not, especially if s/he has access to the MTA's
logs.  If the mail is never delivered but fails some sort of SMTP VRFY,
then you would most likely have to enlist the help of your own postmaster
(or intermediary LISTSERV-maintainer' host).
