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!
