event bus verticle that supports sending mails via a MailService instance running on
another machine via the event bus

when the standard config can be used (send mails via localhost:25 without login)
it is possible to deploy the verticle with the id
vertx run client:io.vertx.mail-client
and send mails from other machines via the event bus with the client address vertx.mail
(on the other hand, if you can send mails via localhost:25, you do not really need the event bus)
