[Dovecot] deliver rewrites envelop-sender

[Gerhard Wiesinger]

Hello!

I'm the author of the procmail patch for dovecot's deliver program.

You can specify -f <envelope sender> with dovecot deliver when I remember 
correctly.

DELIVER_PROGRAM="/usr/libexec/dovecot/deliver -m \$BOXNAME -d \$RECIPIENT -f SOMETHING_ELSE -c /etc/dovecot.conf"
(Can't remember whether there was a variable for the from user or not, 
when yes you can specify the from user, too.
)
When you need any help feel free to contact me.

BTW: The First from line is only the mbox delimiter and really has no 
effect on the Mail headers. I also have MAILER-DAEMON in the From line 
without any problems at all. So this is IHMO only cosmetic.

@Timo:
Running /usr/libexec/dovecot/deliver (without any parameters waiting for 
stdin) and pressing Ctrl-C => Core dump with dovecot 1.0rc17.

Grüße aus Wien :-)

Ciao,
Gerhard
