The MailMessage class can be considered the foundation class of the System.Net.Mail namespace.

The MailMessage class can be considered the foundation class of the System.Net.Mail namespace.

Instances of the MailMessage class are used to construct e-mail messages that are transmitted to an SMTP server for delivery using the SmtpClient class.

The sender, recipient, subject, and body of an e-mail message may be specified as parameters when a MailMessage is used to initialize a MailMessage object. These parameters may also be set or accessed using properties on the MailMessage object.

The MailMessage class also allows an application to access the headers collection for the message using the Headers property. While this collection is read-only (a new collection can not be set), custom headers can be added to or deleted from this collection.
