And I was getting errors on sending emails until I REALLY looked at the
messages in maillog and figured out that I needed:

cat <<EOF>>master.cf || exit 1
#
# Dovecot LDA
dovecot unix - n n - - pipe
flags=DRhu user=vmail:mail argv=/usr/libexec/dovecot/deliver -d
\${recipient}
#
# Vacation mail
vacation unix - n n - - pipe
flags=Rq user=vacation argv=/var/spool/vacation/vacation.pl -f
\${sender} -- \${recipient}
EOF

Robert, please RTFM the shell's manpage, and look up the section
on "here documents" and their quoting rules.

Thank you. I will.
