[exim] Sender:

Did exim developers change sth in exim 4.60
with Sender header? I don't see it in
http://www.exim.org/ftp/ChangeLogs/ChangeLog-4.60
but looks like has shown up.

Sender header in default config is IMO useless,
that info is also in envelope-from. Newest
Outlook 11 uses it as To: while replaying.
Probably other MUA also (Pine?).
