[Mono-list] mono 2.0 send mail to gmail account error

[Suvi/mg3]

This article describes CERT in detail :
http://www.mono-project.com/UsingTrustedRootsRespectfully

And looks not working for me.

My program is Web Application, I have no idea how to operate It using
System.Net.SmtpClient.

I have import the certs by certmgr, like this:

certmgr -ssl -m smtps://smtp.gmail.com:465

Any advice?
