Yes I have put up the latest version, but you'll also note in my previous posting that I had pre-Tested if this was likley to work using MS Explorer for Macintosh which does a similar thing.
It didn't
Here is an extract of the mail headers showing where things are falling apart
Return-Path: <ad@bepp.co.uk> Received: from punt-1.mail.demon.net by mailstore for andy_daws@buppub.demon.co.uk id 908959608:10:18316:15; Wed, 21 Oct 98 08:46:48 GMT Received: from mail.bepp.co.uk ([195.153.2.2]) by punt-1.mail.demon.net id aa1113983; 21 Oct 98 8:46 GMT Received: from 195.153.2.3 (unverified [195.153.2.3]) by mail.bepp.co.uk ^ Here is where things are falling down this was previously the domain name, it will only verify if the fully qualified hostname is entered. It checks to see if the hostname resolves to the same IP it already has but not the other way (So even MS have got it wrong in Express no surprise there some might add), I assume this is for security.
