[2005] Smtp Mail

[yulyos]

Hi,

I do not have an e-mail account from my internet service provider.

I have an e-mail account of gmail, and I want to send an e-mail from an application that I'll build with Microsoft Visual Basic 2005 Express Edition.

Example that not work:

Imports System.Net.Mail
 
        Dim Mail As New System.Net.Mail.MailMessage
 
        With Mail
            .To.Add("MailAddress")
            .From = New MailAddress("MailAddress")
            .Subject = "Some Subject"
            .Body = "Some Body"
        End With
 
        Dim smtp As New SmtpClient("smtp.gmail.com")
 
        smtp.Send(Mail)
 
        smtp = Nothing
        Mail.Dispose()
 
        MessageBox.Show("Your message has been sent")

But if I have an e-mail account from my internet service provider and I'll change the line:

Dim smtp As New SmtpClient("smtp.gmail.com")
To:
        Dim smtp As New SmtpClient("smtp.internet service provider")

Then the program is working OK

Can somebody help me or have suggestion or some example?

Thanks in advance
