[Dovecot] Deliver, sendmail & envelope From_

[Rich Winkel]

Sorry, couldn't find this in the archives.

Under freebsd 4.x, the native mail.local that sendmail uses by
default writes From_ lines that include the origin address.  This
is very readily parsable and handy for quick greps in mboxes.  But
deliver defaults it to MAILER-DAEMON.  I see you can specify the
envelope From_ with "-f", but I'm not sure how that's useful.

Also I'm trying to figure out the instructions for making deliver the
default delivery program under sendmail.  This is a very plain vanilla
setup I have here, procmail is not configured into sendmail.cf so I'm
not sure how to adapt the instructions at wiki.dovecot.org/LDA/Sendmail
Any help would be much appreciated.  I've appended my local mailer 
stuff below.  Should I just substitute deliver's path for mail.local?

By the way, dovecot is very slick!  It should speed up my
mail server by a huge factor.  Many thanks to Timo!
