How do I stop someone using my domain for Spam emails?

Hi Blog Readers,

Every now and then I seem to have one of those low life Viagra sellers using my domain for spam emailing people.

I have done everything I can think of to try and prevent then from doing this, but they seem to keep doing it.

I just wondered if anyone out there new of a way to stop them?

The headers from one of the bounce backs look like this:
Return-Path: <>
Received: from (
by with SMTP id o8si307731weq.161.2010.;
Fri, 23 Jul 2010 05:33:59 -0700 (PDT)
Received-SPF: fail ( domain of does not designate as
permitted sender) client-ip=;
Authentication-Results:; spf=hardfail ( domain of does
not designate as permitted sender)
Message-ID: <>
Date: Fri, 23 Jul 2010 14:33:52 +0200
From: Garnett Mckinnie <>
MIME-Version: 1.0
Subject: Where we are well established we are

As you can see from the headers, I have setup the SPF record and it is receiving a "hardfail"

We are using Google Apps for our email hosting, so you'd kinda hope that they have got things pretty much secured down, so what I am missing? Or is it always going to be possible for other people to fake sending emails using another domain?

Umbraco Bingo

This year's Umbraco Code Garden Conference ( Festival ) was excellent, it was great to see so many familiar faces again, to see some inspiring talks and to enjoy the local beverages!

It has become a bit of a tradition at Umbraco conference's to host a Bingo game where the prizes are various Umbraco branded accessories, only a true Umbracoholic would want ;-)

This year, the luck gods were shinning down on me and I won the "grand prize" delivered by a "motorcycle courier" as it was such a large present... at least, that was the build up to finding out what it was! So everyone including myself were thinking, if this is that big, how on earth will I get it on the plane home!

Luckily, it was actually easy to fit in the luggage, as you will see below :)
