Remarks

The MailDefinition property returns a reference to a group of properties that you use to define the format and content of the email message that is sent to new users. Common settings include the subject line and the sender's return address. For a complete list of properties, see the MailDefinition class.

The MailDefinition property is read-only; however, you can set the properties of the MailDefinition object it returns. You can set the MailDefinition properties declaratively in the form Property-Subproperty, where Subproperty represents a property of the MailDefinition class (for example, MailDefinition-Subject). You can also set the properties programmatically in the form Property.SubProperty (for example, MailDefinition.Subject).

An email message is sent to new users only if MailDefinition is not null and if Body is not empty or null. In that case, the SendingMail event is raised and an attempt is made to send the email message. The From property must be set to an email address. Otherwise, an HttpException exception is thrown.

When the email message is created from the MailDefinition object, it will make the substitutions listed in the following table.

Substitution text Replaced with
<%UserName%> The user name of the newly created user account.
<%Password%> The password for the newly created user account.

If the IsBodyHtml property of the MailDefinition object is true, the contents of the mail message will be HTML encoded to guard against cross-site scripting security vulnerabilities for the message recipient.

You can use the OnSendingMail method to modify the MailMessage created by the MailDefinition object.

This property cannot be set by themes or style sheet themes. For more information, see ThemeableAttribute and ASP.NET Themes and Skins.

Note

It is not possible to guarantee that a user will receive or view an email message. To verify that a user has received a notification by email, consider providing a confirmation link in the email message that enables the user to confirm that the notification was received.
