Cannot set Mail for Domain in Server Features

Hi there,

I have had a server for a short while now (CentOS7), and never used email.

I am now coming to set it up, but 'Mail For Domain' doesn't exist as one of the options against the Features on the Virtual Server config.

Why would this be do you think?

Both Postfix and Dovecot report they are running from Bootup and Shutdown, but they don't appear under 'Servers Status' on the front page.

Any suggestions would be very welcome!

Thanks, Craig
