SMTP authentication

Some SMTP servers require that you provide username/password authentication to allow you to send email. This is typically used to prevent unauthorized users from using the SMTP server as a relay for sending spam.

After establishing a connection with an SMTP server you can login by invoking the Login method of an Smtp instance providing your username and password as arguments.

Example

[C#]

Smtp smtp = new Smtp("smtp.myserver.com");

smtp.Connect();

// login

smtp.Login("jsmith","secret");

[Visual Basic]

Dim mySmtp As Smtp = Nothing

mySmtp = New Smtp("smtp.myserver.com")

mySmtp.Connect()

' login

mySmtp.Login("jsmith", "secret")
