I tried to create an alias domain with postfix 2.3.2, but had this
404: The requested URL /create-alias-domain.php was not found on this server
This is not surprising because, the server uses https, and this is the
port I originally connected to to use postfixadmin, yet when I click on
the linkto call create-alias-domain.php, it ends up going to an http
port. However, there is nothing listening for this domain on the http
port, so it'll never be found.
