Sure that you want to advertise that you do this?
Both '.' and '/' are perfectly valid for the LHS of an email address.
An address such as <../../../../../../../etc/passwd@???> should
be passed on by any mail-system as syntactically correct.
Perhaps ${tr{${local_part:${extract{1}{,}{$recipients}}}}{/.}{_,} would
help; but then "first.last" becomes "first,last". I'm not sure I want
to know what happens when you do a "save /path/.." though. :^)
