There is also Exim's Envelope-To: header which is sometimes useful for
a catchall maildrop scenario. Fetchmail, by default, also makes use of
X-Envelope-To:. If i remember right sendmail can be configured to add
X-Envelope-To:.

Which, as another posted pointed out, is mainly used for mail filtering.

Maybe the envelope address header to be added can be a config file option?
