SmtpClient not accepting self-signed certificate

Hi!

I've got a little Problem with the System.Net.Mail.SmtpClient class in the .NET Framework 2.0

Sending eMails without authentication works fine, however, if use my personal SMTP server which requires STARTTLS (special directive for SMTP-time upgrade to an SSL connection), the sending process causes an exception, saying

"The remote certificate is invalid according to the validation
procedure"

The SMTP server in question uses a self-signed SSL certification, which I think is the problem here. Can I somehow make the SmtpClient class accept self-signed certificates.
