SmtpAccess Enumeration

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

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

public enum SmtpAccess
public enum SmtpAccess
public enum SmtpAccess

 Member nameDescription
ConnectConnection to an SMTP host on the default port (port 25). 
ConnectToUnrestrictedPortConnection to an SMTP host on any port. 
NoneNo access to an SMTP host. 

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.

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

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

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