The Delivered-To header serves a different purpose, and only has local
significance (and should not really go over the network, btw, as it may
confuse people's mail filters!)

I, too, think the Sender: header should be usable for mail filtering.

They are "hardly" compliant, i.e. these headers "should not" be added,
instead they should be prefixed with "X-", but both headers are
quasi-standard, and are not strictly forbidden.

In case anybody wants to know: the Delivered-To: header is a very useful
thing (think multidrop mailboxes!) for people reading their mail through
pop3 or other protocols without envelope information like pop3 or unix mail
folders. Sendmail is incapable of adding this header without hacking, btw...
