Unknown SMTP host exception...

Hi,

I am also getting the same error. I have gone through the FAQs and followed the same steps as they have mentioned there, but I still get the same error, I have tried with different smtp servers like gmail and yahoo but without any success..Someone please help.

Thanks in advance

Hi,

As mentioned in the debugging steps, I turned the debugging session on by "session.setDebug(true);".I got the following printed on my console:

DEBUG: setDebug: JavaMail version 1.4ea

DEBUG: getProvider() returning javax.mail.Provider[TRANSPORT,smtp,com.sun.mail.smtp.SMTPTransport,Sun Microsystems, Inc]

DEBUG SMTP: useEhlo true, useAuth false

DEBUG SMTP: trying to connect to host "smtp.gmail.com", port 25, isSSL false

I also tried to use telnet to connect as

telnet smtp.gmail.com 25

Here I got an output like

Connecting To smtp.gmsil.com...Could not open connection to the host, on port 25

: Connect failed

so now I donot understand wher the problem lies actually.

Can you please suggest anything?

Thanks
