I am trying to use the JavaMail to send messages.
Unfortunately i can't connect to the mail server. I get the following message:
"Exception in thread "main" javax.mail.SendFailedException: Sending failed;
nested exception is:
javax.mail.MessagingException: Could not connect to SMTP host:, po
rt: 25;
nested exception is: Connection refused: connect
at javax.mail.Transport.send0(
at javax.mail.Transport.send(
at JDCAttach.main(
I already checked that the mail server is on.
What's the problem???

means exactly that, the remote server is not accept this connection attempt.
Have you tried, from the machine where your program is running, the command

If you get standard "220 sendmail response" - e.g.

then it may be a security thing for the program

I have no java certifications. This makes me a bad programmer. Ignore my post.
I agree. Here's the link:
