ot: 2.2 ghettoforge install systemctl Q

[voytek at sbt.net.au]

I've installed new Centos 7 with Dovecot 2.2 from ghettoforge and, used
/etc/dovecot from current Centos 6 Dovecot 2.1

I can start/stop Dovecot with dovecot / doveadm stop

BUT when I tried 'systemctl' I get

# systemctl status dovecot
● dovecot.service - Dovecot IMAP/POP3 email server
   Loaded: loaded (/usr/lib/systemd/system/dovecot.service; disabled;
vendor preset: disabled)
   Active: inactive (dead)
     Docs: man:dovecot(1)
           http://wiki2.dovecot.org/

how do I fix this, or, do I need to fix it ?

or maybe I need to pursue this on ghettoforge list
