I am running Dovecot 1.0-rc6 along with dovecot-sieve from 2006-10-05 CVS. I am calling dovecot deliver from Postfix (main.cf):

mailbox_command = /opt/dovecot/libexec/dovecot/deliver

Upon switching to dovecot deliver, I observed two problems:

1. An extraneous "From " header now appears at the top of each message delivered, e.g.:

From dovecot.deliver Fri Oct 06 19:59:57 2006 From sfs@tc.umn.edu Fri Oct 6 19:59:57 2006 Return-Path: sfs@tc.umn.edu

Using Postfix delivery the first of these lines does not appear. This, of course, confuses MUAs.

Don't give F flag to Postfix's pipe command.

The messages in question are accepted by the Postfix smtpd process and processed by Postfix, and handed off to dovecot deliver. I am not specifying an F flag anywhere. If I remove the "mailbox_command" I specified above, Postfix delivers the mail with only the one "From " header -- with the mailbox_command above (no options specified), I get two "From " headers.

Although this reminds me that the "dovecot.deliver" is wrong in there.. Hmm. I think I'll add a maildrop-compatible -f <envelope> parameter here.

How will this help me? I don't even want the added "From " header. If Postfix is not supposed to be writing one, then how do I tell it not to and how does Postfix tell dovecot deliver what to put in the "From " header it writes? (It must be the proper return address seen in the original SMTP transaction as the MAIL FROM value)

There, done in CVS. I'll also make 1.0rc8 release today.

2. The "Content-Length:" header appears after a blank line, essentially putting it into the RFC822 body, e.g.:

User-Agent: Mutt/1.4.2.1i X-UID: 11510 Status: X-Keywords:

Content-Length: 200

test

Are you sure it's a blank line? Dovecot adds lots of spaces after X-Keywords which could just make it look like that.

You're correct; the line prior to the "Content-Length:" header was indeed an "X-Keywords:" header padded out to exactly 80 characters, making it appear that there was an extra blank line after it (my xterm window is set to 80 columns).
