It appears that your SMTP server doesn't support the basic LOGIN method (nor does it report what methods it supports).
Try changing the SmtpAuthMethod property to "NONE", "PLAIN", "CRAM-MD5", or "NTLM" to see which one ultimately works. If you need NTLM authentication, then you may also need to set the SmtpLoginDomain property.
