An SMTP client for Windows Store apps (WinRT and UWP). Send emails from within your Windows Universal App.

You can download and build this project or simply install it via NuGet:

PM> Install-Package lightbuzz-smtp

This requires the 'internetClient' Capability to be enabled in the Package.appxmanifest of the universal app.

Import the assembly to your project and include its namespace:

using LightBuzz.SMTP;

This is an example of using your own SMTP server. Check below for using Gmail and Outlook.

using (SmtpClient client = new SmtpClient("smtp.example.com", 465, false, "[email protected]", "Pa$$w0rd"))
{
        EmailMessage emailMessage = new EmailMessage();

        emailMessage.To.Add(new EmailRecipient("[email protected]"));
        emailMessage.CC.Add(new EmailRecipient("[email protected]"));
        emailMessage.Bcc.Add(new EmailRecipient("[email protected]"));
        emailMessage.Subject = "Subject line of your message";
        emailMessage.Body = "This is an email sent from a WinRT app!";
        
        await client.SendMailAsync(emailMessage);
}

Server: smtp.gmail.com
Port: 465
SSL: True

Since this does not use OAUTH2, Gmail considers this a "less secure app". To use this with Gmail, the "Access for less secure apps" setting on the account will have to be changed to "Enable".

Server: smtp-mail.outlook.com
Port: 587
SSL: False (upgarde SSL after STARTTLS)
