You probably need to supply a username and password to relay messages through that SMTP server.
 Hello,

 I am sending two emails from the same procedure, one to myself (while testing) and another (a comfirmation) to the user on the website.

 I was having difficulty finding a relay server to SMTP though, but was able to do this though one of my personal account, Cabbage.Org.  It doesn't make any sense to me why this works and no other account, including localhost and the remote server which hosts the website.

 Here is a code snippet showing the sending of both emails:

 **************************
 Dim MailObj As New System.Net.Mail.SmtpClient

 MailObj.Host = "smtp.youthkaraoke.org"

 MailObj.Send("mail@dragonimports.com", "msam@cabbage.org", strSubject, strBody) 'Change msam@Truckloads.Net to working email

 'Send confirmation to sender

 strBody = "Thank you for submitting your request to Dragon Importing" + vbNewLine + _

 "You will be contacted soon by one of our reprresentives!" + vbNewLine + vbNewLine + _

 "The Dragon Importing Staff"

 MailObj.Send("mail@dragonimports.com", txtEmail.Text, "Confirmation", strBody)

 *********************************

 In the first send, msam@cabbage.org is the recipient and the letter goes through without a problem.  In the second, if the value of txtEmail.Text is msam@cabbage.org, then no problem either, but if any other email address is used then I get this error:

 Server Error in '/' Application.

 Any help I can get is appreciated.

 Thank you and God Bless,
