The SmtpPermission and SmtpPermissionAttribute classes control access to SMTP host computers. The SmtpClient class demands an SmtpPermission when sending electronic mail to the SMTP host for delivery.

The SmtpAccess enumeration specifies the level of access controlled by an instance of this permission.

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
