It seems that the variable 'host' is an empty String.

Dude, do not use TAB characters to indent Usenet posts.

Use a maximum of four spaces (that's space characters) per indent level.

Is that why it's trying to mail via localhost?

Which'd be fine if localhost were running a mail service on port 25.

One wonders why in

the lack of the "smtp.gmail.com" property is not logged, nor even a logger
defined for the class, especially after all that superfluous effort to
initialize the root logger.

Don't allow preconditions (or other invariants) to fail silently.

Either that or there is no MTA listening on localhost:25

(SMTPTransport.java:

That results from attempting to connect to an SMTP service running on
your computer, and there is none running.

Presumably the lookup for smtp.gmail.com in System properties fails.
Hardly surprising really, why would it exist in the System properties? So
host is set to an empty string. Not knowing what the
org.codemonkey.vesijama.Mailer class does with the "host" argument if
it's empty, I am guessing that it attempts a connection to localhost.
Since you don't have a SMTP service running the connection fails with a
MessagingException and you get a stack trace.

I think you would have better success if you set the host, username and
password variables to the values you attempt to lookup in System
properties.

Thanks for the wakeup, now I'm heading for the next trouble.

It seems I need an https connection to get to gmail.
