I am using this sample to try to get it to work. I modified it to get it to work, but giving me the error too.
the CODE:
Set Mailer = Server.CreateObject("SMTPsvg.Mailer"

Mailer.FromName = "nfabk.org"
Mailer.FromAddress = "webmaster@nfabk.org"
Mailer.RemoteHost = "mail.nfaexchange.org"
Mailer.AddRecipient Request.QueryString("FName"

, Request.QueryString("EmailAddr"

strMsgHeader = "You had a form submitted" & vbCrLf
for each qryItem in Request.QueryString
strMsgInfo = strMsgInfo & qryItem & " - " & request.querystring(qryItem) & vbCrLf
strMsgHTML = strMsgHTML & qryItem & " - " & request.querystring(qryItem) & "<BR>"
next
strMsgFooter = vbCrLf & "End of request"
Mailer.BodyText = strMsgHeader & strMsgInfo & strMsgFooter
if Mailer.SendMail then
Response.Write "<html><head><style> P { font-family: georgia;font-size: 12px;color: #000000; }<\style>"
Response.Write "<body><p>Your mail has been sent. Here is what you entered in the form</p>"
Response.Write "<P>" & strMsgHTML & "</p></center>"
Response.Write "Thanks for visiting On Point Web Designs and letting us help you out</p>"
Response.Write "click <a href=""aspTut6.asp"">here </a> to go back</p>"
else
Response.Write "Mail send failure. Error was " & Mailer.Response
end if
