SmtpAccess Enumeration

.NET Framework 4

Other Versions

Specifies the level of access allowed to a Simple Mail Transport Protocol (SMTP) server.

Namespace: System.Net.Mail
Assembly: System (in System.dll)

Syntax

C++

Copy

public enum SmtpAccess

Members

	Member name	Description
	None	No access to an SMTP host.
	Connect	Connection to an SMTP host on the default port (port 25).
	ConnectToUnrestrictedPort	Connection to an SMTP host on any port.

Remarks

The SmtpAccess enumeration is used by the SmtpPermission and SmtpPermissionAttribute classes to specify a level of access to an SMTP host computer. The SmtpClient class demands an SmtpPermission when sending electronic mail to the SMTP host for delivery.

Examples

The following code example uses the SmtpAccess enumeration to create a permission object.

C++

Copy


public static SmtpPermission CreateConnectPermission()
{
    SmtpPermission connectAccess = new 
        SmtpPermission(SmtpAccess.Connect);
    Console.WriteLine("Access? {0}", connectAccess.Access);
    return connectAccess;
}
