: the symptom "no error but no mail received" usually means ASP/CDO handed the message to the SMTP subsystem but the SMTP server never delivered it. fixed the ASP syntax (that gets the message to SMTP). correctly warned about modern anti-spam — many public providers will reject mail from unauthenticated hosts or from dynamic/home IPs.

Quick practical checks

  • Look in the local SMTP folders (default IIS SMTP: C:\Inetpub\mailroot\Pickup and C:\Inetpub\mailroot\Queue) to see whether messages are being queued or stuck.
  • Enable and inspect SMTP logging and Windows Event Viewer (Application/System) for delivery errors or authentication failures.
  • Verify the SMTP server allows relay from localhost (127.0.0.1) and that firewall/ISP are not blocking outbound SMTP (port 25 or submission ports 587/465).
  • If the message leaves the queue but never arrives, check remote SMTP response codes in the logs (they explain whether the remote server rejected it).

If the local SMTP cannot relay, configure CDO to use an authenticated SMTP relay (ISP or service) instead of relying on the machine as a mail server. Example configuration (replace host/credentials as needed):

<%
' configure CDO to use an authenticated SMTP relay
Set cfg = Server.CreateObject("CDO.Configuration")
With cfg.Fields
  .Item("http://schemas.microsoft.com/cdo/configuration/sendusing") = 2
  .Item("http://schemas.microsoft.com/cdo/configuration/smtpserver") = "smtp.example.com"
  .Item("http://schemas.microsoft.com/cdo/configuration/smtpserverport") = 587
  .Item("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate") = 1
  .Item("http://schemas.microsoft.com/cdo/configuration/sendusername") = "username"
  .Item("http://schemas.microsoft.com/cdo/configuration/sendpassword") = "password"
  .Item("http://schemas.microsoft.com/cdo/configuration/smtpusessl") = True
  .Update
End With
' assign cfg to the message before Send
%>

Deliverability notes and cautions

  • Use an authenticated sender address that matches the relay account; many hosts drop mail that spoofs domains.
  • For reliable delivery to Yahoo/Hotmail/Gmail, use an authenticated relay or a reputable transactional SMTP service, and publish SPF/DKIM for the sending domain.
  • If testing on Windows XP, consider testing the same code on a server OS or against a known external SMTP relay to isolate OS/service limitations.

Set myMail=CreateObject("CDO.Message")
myMail.Subject="This is the subject"
myMail.From="vishesh91@@hotmail.com"

you first try to use your code in windws2000 withount any change, it might work there.

yahoo/hotmial and other mail ervers has started new technique known as antispam, so these new domains wont be able to sent mails to these server unless you register your domian through process.
