That's why I included the portion from my master.cf
The portion of my master.cf
81 # SPB - Attempt to deliver with Dovecot LDA
82 dovecot unix - n n - - pipe
83 flags=DRhu user=mailsystem argv=/usr/lib/dovecot/deliver -f
${sender} -d ${user}@${nexthop}
The numbers are just line numbers from vim. The entry reads like:
# SPB - Attempt to deliver with Dovecot LDA
dovecot unix - n n - - pipe
flags=DRhu user=mailsystem argv=/usr/lib/dovecot/deliver -f
${sender} -d ${user}@${nexthop}
malsystem is the user and /usr/lib/dovecot/deliver exists.
