Sending emails with Blatt

Dim client As New SmtpClient("some smtp server name or ip address goes here")
Dim fromAdd As New MailAddress("trainsdse@hotmail.com", "Thomas Smith")
Dim toAdd As New MailAddress("admin@avfire.com", "Thomas at the Fire Dept.")
Dim message As New MailMessage(fromAdd, toAdd)
message.Subject = "Here's the subject"
message.Body = "Here's the body"
client.Send(message)

I'm not sure about Blatt - if you want to use another email client rather than sending direct to the SMTP server then you would need to look to the vendor for details on there object model/API's that would allow you to send emails through there application and have this configured to use the SMTP server.
