System.Web.Mail

[SJR3t2]

I have re-installed .NET 1.1 and SP1 on multiple computers, one with
Win XP Pro and another with Win 2003, and I can't seem to get the
System.Web.Mail namespace and SmptMail and MailMessage classes. What
do I need to do to access this namespace along with the classes?

Note that if that's not an ASP.NET project, you have to explicitly add
reference of System.Web namespace to the project in order to access it.

Thanks Lau Lei Cheong, I can now compile. But I get this error.

Any suggestions?

A 530 error means that your email server requires authentication.
