java mail give java.net.connectexception: connection refused

Question

I have the same code on windows and it works well. When i move the code to centos, it gives the exception: javax.mail.MessagingException: Could not connect to SMTP host: stmp.gmail.com, port: 587; nested exception is: java.net.ConnectException: Connection refused

Could anyone please give me some suggestion about this exception?

Thank you very much.

Solution 1

You have made a spelling error! It should be "smtp.gmail.com" not "stmp.gmail.com".

Solution 2

'Connection refused' means one of two things. Either the host:port you specified is incorrect or an intervening firewall isn't playing ball.
