||This is an excellent tutorial on
using ASP to send email using CDONTS which is installed by default on all IIS
With this you could send mail from any asp page. Read on and download the
zip file for all the source code.
If you are reading this page
then I shall assume that you already know a little bit about ASP and running ASP
The download to this tutorial has 4
working examples of E-mail Form's which you can use to allow your web site
visitors to send there comments or enquiries to your e-mail address or send
e-mails to there own friends form your site.
However, I not going to go into how the form is written
going to concentrate on the actual methods and properties the CDONTS NewMail
object uses to format and then send the e-mail.
CDONTS stands for 'Collaboration Data Objects for Windows NT Server' and as
the name suggest it is for NT, sorry Win9x users you don't have this component.
The CDONTS component is installed when you install IIS on NT4 and Windows 2000.
Although the component will run on Windows XP, Microsoft have decided to remove
the component from IIS 5.1 on Windows XP, so you will have to track down a copy
of the cdonts.dll and register it on the IIS web server.
To use this
component to send e-mail you also need the SMTP Server that ships with IIS 4 or
5 installed on the web server. The SMTP server is usually installed by default
with the standard IIS installation.
First we need to create the variables
that we are going to be using in this script.
need to create an instance of the 'CDONTS NewMail'
object on the server.
Set objCDOMail =
the 'NewMail' object has been created on the server we
can use various properties and methods of the 'NewMail' object to build the e-mail.
First we are
going to use the 'From' property to let the recipient
of the e-mail know who the e-mail is from. If you leave this property out or do
not have a properly format e-mail address the e-mail will fail.
we need to place a string value representing the e-mail address of the person
you want to receive the e-mail into the 'To' property
of the 'NewMail' object.
next property 'Cc' holds the e-mail address of the
people you wish to receive Carbon Copies of the e-mail.
You can place
one or more recipient e-mail addresses separated by either a comma (,) or a
semicolon (;). Make sure all the e-mail address are properly formatted or the
e-mail will fail.
This property can be left out if you don't want any
carbon copies of the e-mail sent.
'Bcc' property holds the e-mail address of the people
you wish to receive Blind Copies of the e-mail. The formatting of the e-mail
addresses is the same as for the 'Cc' property
Again if you don't want to send any blind copies of the message
you can leave this property out.
the next line we use the 'Subject' property to set the
subject of the e-mail.
objCDOMail.Subject = "Enquiry sent from my web
As well as sending
plain text e-mail's you can also format the body of the e-mail using HTML. The
default is Text but if you wish to format the e-mail using HTML then you will
need to use the 'BodyFormat' property with the integer
value of '0' for HTML or '1'
If you leave this property out the e-mail will be sent as plain
If you wish to use HTML
formatting in the e-mail, as well as setting the 'BodyFormat' property above to HTML, you will also need to
set the 'MailFormat' property to MIME. Again this
property uses and integer value of '0' for MIME
and '1' for Text.
The default is text so if
your e-mail is text only you can leave this property out.
The next property were
covering is the 'Body' property. This property holds
the main part of the e-mail with the message you are sending.
have set the 'BodyFormat' property to HTML and the
'MailFormat' to MIME then you can use HTML to format
your e-mail message. 'eg.
<h2>Hello</h2><br><b>This is my e-mail in HTML
If you want to send the e-mail as text then you
can just enter text instead. 'eg. Hello This is my e-mail in
"<h2>Hello</h2><br><b>This is my e-mail in HTML
'Importance' property tells the mail messaging system when to schedule delivery
of the e-mail.
For this property there is 3 different integer values,
0 - Low, the e-mail will be sent during times of low
system use, 1 - Normal, the message is sent at regular
delivery times, 2 - High, the system will attempt to
send the message immediately.
If this property is left out the deafault
objCDOMail.Importance = 1
Once all the properties
for the e-mail are set we can now send the e-mail using the
once the e-mail has been sent we can close the server object releasing server
|'Close the server object|
Set objCDOMail = Nothing
other methods and properties of the 'NewMail CDONTS'
object but to keep things simple I have tried to cover the most common
properties needed to send an e-mail from your web site.
