The library used for sending e-mail (Email::Sender)
includes a wide variety of transports that can be used to configure the library to (pretend to) send
e-mail messages. For a list of available transports, see https://metacpan.org/dist/Email-Sender.
Should a different delivery method be required even considering the list of available transports,
this can be achieved by implementing a custom Email::Sender::Transport.
