Send Email with Gmail

This sample base on vb.net 2005.

There are two step to create this.

1. You must insert mailSettings tag in app.config for window application or insert in web.config for web application.

2. Use System.Net.Mail namespace.

Sample Code for window application.
1. Insert this tag in app.config (Config Google SMTP).

2. Use System.Net.Mail namespace.

Imports System.Net.Mail

Sub SendEmail()

Dim client As New SmtpClient()
Dim sendTo As New MailAddress("sendToAccount@gmail.com")
Dim from As MailAddress = New MailAddress("from@address.com")
message As New MailMessage(from,sendTo)

message.IsBodyHtml = True
message.Subject = "HI"
message.Body = "Got it!!"

' Use the same account in app.config to authenticate.
Dim basicAuthenticationInfo As New System.Net.NetworkCredential("yourAccount@gmail.com", "YourPassword")

client.Host = "smtp.gmail.com"
client.UseDefaultCredentials = False

client.Credentials = basicAuthenticationInfo
client.EnableSsl = True



Catch ex As Exception

Console.WriteLine("SEND FAIL")

End Try

End Sub

Hi Guys, this code did work when I used something very similar some time ago but now it keeps failing with this error msg

"No connection could be made because the target machine actively refused it"

Could it be something to do with the firewall of my company's n/w? Any other suggestions that could help me? Thks
