I'm sorry, I forgot to specify that I was using Debian Linux: case "$1" in start) if grep protocols /etc/dovecot/dovecot.conf | sed 's/#.*$//' | tr -d '"' | \ egrep -q '[^#]*(\bpop3s?\b|\bimaps?\b)'; then if [ -x /usr/lib/dovecot/imap-login -a -x /usr/lib/dovecot/imap ] \ || [ -x /usr/lib/dovecot/pop3-login -a -x /usr/lib/dovecot/pop3 ]; then echo -n "Starting $DESC: $NAME" ulimit -n 8192 start-stop-daemon --start --quiet --oknodo --exec $DAEMON echo "." fi fi ;; stop) echo -n "Stopping $DESC: $NAME " start-stop-daemon --stop --quiet --oknodo --exec $DAEMON echo "." ;; > ?
