+** REMOTENAME -- return the name relative to the current mailer

+** Parameters:
+** name -- the name to translate.
+** m -- the mailer that we want to do rewriting relative
+** to.
+** senderaddress -- if set, uses the sender rewriting rules
+** rather than the recipient rewriting rules.
+** canonical -- if set, strip out any comment information,

+**
+** Returns:
+** the text string representing this address relative to

+**
+** Side Effects:
+** none.
+**
+** Warnings:
+** The text string returned is tucked away locally;
+** copy it if you intend to save it.
