Sending a mail

[Joey Alencar]

Hi,
I've tested my application in my network (that have no Firewall) and my application sended e-mails normally. But when I installed the same application on my client and I tried to send an e-mail, this message appeared:

SENDING FAILED; NESTED EXCEPTION IS: JAVAX.MAIL.MESSAGINGEXCEPTION: UNKNOWN SMTP HOST: 128.1.0.17:8080; NESTED EXCEPTION IS: JAVA.NET.UNKNOWNHOSTEXCEPTION: 128.1.0.17:8080  

Is the Firewall blocking my application? If it's the firewall, how can I send a mail under a Firewall?
Thanks.

I have no idea why your mail program is generating that error, however, I would advise you or a Bartender to edit your Post and take out the IP addresses you have posted. That just seems like a hackers dream to have that kind of information.
