Yes, actually that was what I meant. Strange, I must have heard
(or read) the expression somewhere... Sorry for the improper usage.

Seems good.

Sendmail handles "Resent-To", "Resent-Cc", and "Resent-Bcc"
the way it handles "To" header, but it does not seem to give any
special precedence to them. Aslo, in some conditions "Resent-" headers
are explicitely dropped, so it is safer to use "to" anyway.
