i believe never.... i dont believe that swsoft will ever use postfix, i dont know why bu last 2 years i only read rumours about postfix but truth is nothing happens
We have a postfix server with mysql support for management
and we are programming a module to connect our plesk servers
directly to the postfix server... after that the mail icon
of postfix will be disabled and all our plesk servers will
manage the accounts directly on our central postfix mail server.
