[Dovecot] init script as provided http://wiki2.dovecot.org/DovecotInit

[Jess Portnoy]

Hello list,

I would add:
# dovecot        Startup script for the dovecot server
#
# chkconfig: - 
# processname: dovecot
# config: /path/to/config
# pidfile: /path/to/pid

So that it supports the chkconfig used by RHEL and clones too.

Also, maybe it should be installed by the Makefile's install target? it 
could then also set:
DAEMON=/path/to/dovecot/daemon
instead of:
DAEMON=/usr/local/sbin/dovecot

Cause naturally, it will know the prefix chosen.

May the source be with you,

Jess Portnoy
