So I'm making a Program to Start/Restart/Stop and running commands from the Console for my Server.
Now when someone uses the console, I want to be alerted of it on my Mail.
I am using Visual Studio 2010.
This is my Code:
Dim mail As New MailMessage Dim smtp As New SmtpClient Try mail.From = New MailAddress("firstname.lastname@example.org") mail.To.Add("email@example.com") mail.Subject = ("Text") mail.Body = ("Some other Text") Dim s As New SmtpClient("smtp.gmail.com") s.Port = 587 s.EnableSsl = True s.Credentials = New Net.NetworkCredential("Mailthatalerts@testmail.com", "password") s.Send(mail) Catch ex As Exception MessageBox.Show(ex.Message) End Try
Of course I hidden some of my personal informations but this is it, when I'm clicking on the button, I get THIS error:
The SMTP Server requires a secure connection or the client was not authenticated. The server response was: 5.5.1 Authentification required. Learn more at
I have another Program that does the same on VB 2008, and it works fine.
Any help would be very appreciated.
Thank you in advance!
