Hello
I don't know where the problem is but I am using netbeans 6.9.1 with tomcat 6.0.2 and have a mail lib trying to send an email but gives me an error on the method: Transport.send( message );
sendEmail(sSMTP, sFrom, sEmail, sSubject, sMessage);
and on the webpage it gives me:
Could not connect to SMTP host: <hostname>, port: 25</hostname>
Can you please give any advices.
It gives me an exception on Netbeans/ tomcat:

Are you sure your configuration is correct, and your SMTP host is actually listening for mail request connections?

The connection is refused.

Please check your email-server. They sometimes have a 'ban' function. It does what it's supposed to do - it bans you with a certain number of false login attempts.

This can be really annoying, specially while development.

Also check if there are "rules" set up during ban, some handle the ban as a simple limited time rule for the server.
