We have a fresh Plesk 12 server where new sites being added are set to have mail enabled, webmail enabled and webmail set to Roundcube. No other webmail options are installed. We're finding new sites get added and show roundcube selected, yet no files exist under /etc/nginx/plesk.conf.d/webmails/ for the domains in question. You have to disable webmail (set it from Roundcube to none) and then set it back to Roundcube, then the relevant files are created and everything works.
Any ideas?
