Determines if wodSmtpServer uses IPv6 protocol.

A Boolean value.  

object.UseIPv6 [= value]

The UseIPv6 Property syntax has these parts:

UseIPv6 determines if component will use IPv6 socket stack addresses to listen for incoming SMTP connections. For local interface definition it will accept both numeric values, such as

fe80::213:20ff:fe91:5bb5

but also fully qualified hostnames that resolve to local IPv6 addresses, such as

www.google.com.sixxs.org

When you supply BindIP property value, only specific IPv6 interface is used for accepting connections. If BindIP is empty, all IPv6 interfaces are listening.

In order to use IPv6, your version of Windows needs to support it. To install it on Windows XP, right-click on your 'network connection interface' icon, select 'Properties', and then check if

Microsoft TCP/IP version 6

is listed. If not, click on 'Install' button, choose 'Protocol' and then locate above from the list. If IPv6 stack is not installed on the computer, this property is ignored.
