I'm working with a proxy server. Can somebody tell me how to fix this
problem?
Thanks, Nilson

The stack trace tells us that it's failing to resolve the hostname,
namely the mail.smtp.host in the properties you handed to
Session.getInstance(). It could be a matter of your /etc/resolv.conf
not being configured or a number of other things.
Try this from the command line:
ping <hostname>
You'll probably get something like "unknown host". One you have
DNS lookups properly configured then your problem should disappear.

Thank you for your answer. I solved the problem this way:

Properties p = System.getProperties();
p.put("http.proxyHost","http-proxy.xx.xxxxx.xx");
p.put("http.proxyPort","8080");
System.setProperties(p);

With this changes you can set your proxy.

Alternatively, try using the IP address of the host instead of its name.

..and then get someone else to sort out the DNS resolution problem ... ;-)
