Remarks

Caution

Code Access Security (CAS) has been deprecated across all versions of .NET Framework and .NET. Recent versions of .NET do not honor CAS annotations and produce errors if CAS-related APIs are used. Developers should seek alternative means of accomplishing security tasks.

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.
