Dovecot on Fedora 20 or 21

Hello,

Is anyone running Dovecot on either a Fedora 20 or 21 system? I'm having an issue, on a system reboot, which I admit does not happen often, Dovecot fails to start in the systemctl list, output is status failed. The issue seems to be Dovecot can not bind to the ipv6 address. Now later if I manually log in to the box and start dovecot it works just fine no problems. I've googled and seen similar issues to this. Does anyone have a solution?

Thanks. Dave.
