//// some times it gives error like

//System.Net.Mail.SmtpFailedRecipientException {"Mailbox unavailable. The

////server response was: 5.7.1 ... Relaying denied. IP name

////possibly forged [208.179.189.145]"}

////System.Net.Mail.SmtpFailedRecipientException

//solution

//You have to allow relaying in your SMTP server.

//Check security settings in IIS.

//This is dine by right-clicking Default SMTP Virtual Server and choosing

//properties.

//Then go to the Access tab. Click on the Relay button at the bottom of the

//dialog.

//Add the IPs you want to grant access. By default this is turned of

//completely and since your web server is on the same machine, you could add

//127.0.0.1 as the only entry in the list.

//You can also open it up completely by checking the radio button All except

//the list below and leave the list blank. However, if it is a public server

//that is not a recommended setting.

//That should solve that issue.

//some times unchecked need to add this code into web.config

//
