I have solved at least another part of the problem that was causing the setuig error. I changed my postfix/master.cf file from this:

dovecot   unix  -       n       n       -       -       pipe
  flags=DRhu user=vmail:vmail argv=/usr/local/libexec/dovecot/dovecot-lda -f ${sender} -d ${recipient}

to this:

dovecot   unix  -       n       n       -       -       pipe
  flags=DRhu user=vmail:vmail argv=/usr/local/libexec/dovecot/dovecot-lda -f ${sender} ${recipient}

taking out the d flag. Now dovecot doesn't complain. *However*, I've *still* got this devil plaguing me:

Oct 25 10:49:18 myserver postfix/pipe[3712]: 0423257901AB: to=<foo at bar.com>, relay=dovecot, delay=109318, delays=109318/0.14/0/0.1, dsn=4.3.0, status=deferred (temporary failure

Ya know, I know I'm not the sharpest tool in the shed when it comes to programming, but I have *never* worked *so hard* on an installation as this one with so little success! It took me a day to install qmail the first time around. I've been a week on this!! Please help me figure this mess out. For the record, I did rebuild dovecot but that obviously didn't help. I did change the posfix files to pump out a bunch of debugging info:

adding a -D flag to every smptd service in master.cf
This in main.cf:
debug_peer_level = 3
debugger_command =
  PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin
  xxgdb $daemon_directory/$process_name $process_id & sleep 5
debug_peer_list = 127.0.0.1
#debug_peer_list =

and it doesn't give me any output like it did the first time, so I assume (perhaps incorrectly) there are no errors.

TIA,
Jack
