I have a simple ASP.NET MVC application with a contact page.

In my development machine (local) I can send successfully emails (I specify host and credentials), but on the production server this doesn't work and I get this error:

System.Net.Mail.SmtpFailedRecipientException: Mailbox unavailable. The server response was: Requested action not taken: mailbox unavailable or not local at System.Net.Mail.SmtpTransport.SendMail...

The server is in my LAN (the mail server too). I tried with multiple accounts but I have errors every time.

Credentials for the account are provided at runtime with

smtp.Credentials = new NetworkCredential("username", "password");

Any idea?

Thanks
