You can use the MAILTO protocol under Internet Explorer to create a hyperlink that opens the clients e-mail system. This article describes the different parameters you can use with the MAILTO protocol.

More information

The format for the MAILTO protocol is as follows:
The Recipients field can be blank, a single e-mail address, or multiple e- mail addresses separated by semicolons (;).

The Parameters are optional and have to be separated by an ampersand (&). Parameters appear in a name/value pair format. Following is the list of parameters available in Internet Explorer:
   ---------     ------------------

   CC=           Carbon copy
   BCC=          Blind carbon copy
   SUBJECT=      Subject text
   BODY=         Body text
Because all the data is passed in the URL, the characters used must be Internet safe characters. Use a %0d for a line feed. Use a %20 for a space NOTE: using plus (+) sign does not work in this protocol.

Here is sample HTML that demonstrates using the MAILTO protocol:

   <A HREF="mailto:email1;email2&cc=email3?subject=Subject%20
   Click Here To Invoke Mail

NOTE: Your e-mail client may behave differently than described above. Internet Explorer passes the mailto: string directly to the default mail application. The mail application can parse the string in whatever way it wants. Microsoft Outlook and Outlook Express parse the string as described above.
