Email Scripts Guideline for ASP on Windows Server
Posted by Senior Sales & Support (Import) on 21 December 2015 01:26 PM

Windows 2000 and Windows XP use CDO messaging as a replacement for CDONTS.

Sending email with CDO is a simple task. First we create a reference to the CDO component Set objMessage = CreateObject("CDO.Message") then fill-in Sender, Subject and Recipient (To) fields of the headers and the body text which can be either plain text or HTML. You can also add a file attachment. You then use the Send method to send the email.

Sending a text email using authentication against a remote SMTP server. More and more administrators are restricting access to their servers to control spam or limit which users may utilize the server. This example shows you how to use basic authentication, the most commonly used authentication method, when the SMTP server you are using requires it. This code is slightly more complex but not very difficult to understand or work with.


Const cdoSendUsingPickup = 1 'Send message using the local SMTP service pickup directory.
Const cdoSendUsingPort = 2 'Send the message using the network (SMTP over the network).

Const cdoAnonymous = 0 'Do not authenticate
Const cdoBasic = 1 'basic (clear-text) authentication
Const cdoNTLM = 2 'NTLM

Set objMessage = CreateObject("CDO.Message")
objMessage.Subject = "Example CDO Message"
objMessage.From = """Me"" <>"
objMessage.To = ""
objMessage.TextBody = "This is some sample message text.." & vbCRLF & "It was sent using SMTP authentication."

'==This section provides the configuration information for the remote SMTP server.

objMessage.Configuration.Fields.Item _
("") = 2

'Name or IP of Remote SMTP Server
objMessage.Configuration.Fields.Item _
("") = ""

'Type of authentication, NONE, Basic (Base64 encoded), NTLM
objMessage.Configuration.Fields.Item _
("") = cdoBasic

'Your UserID on the SMTP server = full email address eg.
objMessage.Configuration.Fields.Item _
("") = "youruserid"

'Your password on the SMTP server
objMessage.Configuration.Fields.Item _
("") = "yourpassword"

'Server port (typically 25)
objMessage.Configuration.Fields.Item _
("") = 25

'Use SSL for the connection (False or True)
objMessage.Configuration.Fields.Item _
("") = False

'Connection Timeout in seconds (the maximum time CDO will try to establish a connection to the SMTP server)
objMessage.Configuration.Fields.Item _
("") = 60


'==End remote SMTP server configuration section==
