Using mailbox_command causes an extra (badly-formed) "From " line as
described previously.  I can't see how anyone could be using this
successfully with Postfix (I'm running version 2.3.3).

As you suggested, I tried the alternate approach of using the pipe transport:
- In postfix/main.cf
  - Commented-out "mailbox_command"
  - Added "mailbox_transport = dovecot"
  - Added "dovecot_destination_recipient_limit = 1"
- In postfix/master.cf I added:
  # Dovecot LDA
  dovecot   unix  -       n       n       -       -       pipe
    flags=DRhu user=dovecot argv=/opt/dovecot/libexec/dovecot/deliver -d ${recipient}

After running "postfix reload", I got this error on the console:
	deliver(syst0003 at diamond.tc.umn.edu): net_connect(/var/opt/dovecot/run/dovecot/auth-master) failed: Permission denied

As such, I then added this to the dovecot.conf auth{} section:
  socket listen {
    master {
      path = /var/opt/dovecot/run/dovecot/auth-master
      mode = 0600
      user = dovecot
      group = dovecot
    }
  }

After doing this, Postfix is still unable to deliver, and the mailq command
shows my attempts there with (temporary failure).  I see no error messages
anywhere that would help me determine what's going on.

Can anyone who is running Postfix+Dovecot LDA give me some pointers here?

I assume that you believe Postfix is doing it, right?

I'm confused.  I thought you just made changes to the Dovecot deliver
program to SET the FROM address to place in "From " headers that it adds...?
