you don't usually install a mail server for each application and make it
public

you usually relay the mail traffic to dedicated mail server.
this dedicated mail server takes care of the mail exchange with the world.
this mail server is responsible for filtering spam or signing messages, so
that they won't be rejected by other mail servers.

reconsider your design. otherwise you should set up an official mail server
with all it takes.
