Too many connections to smtp server

[viewpnt]

On error, emailcli opens too many connections to smtp server, not even notifying the user about the error...

In my case, invoking the program like this...

./email --username user@mail.com --host smtp.server --port 587 --subject "Test mail" --body "Test Body" test@email.com

Does not show any error, but smtp server side I got...

Maybe there should be a --verbose option showing the error, or better yet, a --debug option, showing all server - client activity...
