authenticating to smtp server / cdo

[anony]

Hi,

I'm trying to use system.web.mail to send an email, but the smtp server
requires authentication. I cam across some info about extra fields allowed
via the following:

Dim mail As New MailMessage()
mail.To = "to@address .com
mail.From = "fr**@address.c om"
mail.Subject = "this is a test email."
mail.Body = "Some text goes here"

mail.Fields.Add ("http://schemas.microso ft.com/cdo/configuration/smtpauthenti
cate", "1") 'basic authentication

mail.Fields.Add ("http://schemas.microso ft.com/cdo/configuration/sendusername
", "username") 'set your username here

mail.Fields.Add ("http://schemas.microso ft.com/cdo/configuration/sendpassword
", "password") 'set your password here
SmtpMail.SmtpSe rver = "smtp.domain.co m" 'your real server goes here
SmtpMail.Send(m ail)
Unfortunatley, I get a compilation error:

'Fields' is not a member of 'System.Web.Mai l.MailMessage'

Can anyone shed some light on how to send mail through an smtp server that
requires authentication?

Thanks much,
Brian

Use .Net Framework 1.1 instead of 1.0 and you shouldn't receive this error anymore
