Error while sending mail

[Kiran Raj]

Hi all,

I am receiving  the following exception when i try to send a mail from a console app in the production machine. the same app seems to work on my dev machine.
i tried google and found some suggestions. they say , this problem is because of permission, code issue, SMTP server name but all seem to be fine as i verified them. I am using System.Web.Mail namespace instead of System.Net.Mail. Posts also say to use the later but as i am working in dotnet 1.1. I cant use System.Net.Mail.
Can anyone help me on this.

Does your SMTP server need some user authorization?

No its does not require any authorization. I can connect and send mails without any from my system.
 Will OS be a constraint as i am working in XP SP2 and mail sending is working but server is windows 2003 R2.

well, does your code look like example on
