Windows Live Hotmail rejecting forwarded emails from ZoneEdit

Monday, 11 June 2007

It's just come to my attention that emails sent to my wife's address via our domain hosted on ZoneEdit are now being bounced by Hotmail as suspect spam. I wonder if this is something to do with the new Windows Live Hotmail service.

Of course they're not spam, and this threw me for a bit.

The bounced emails contain a link to various resources about how to fix the problem.

A quick search of Google on "hotmail zoneedit" hinted that it might be possible to add extra detail to DNS to placate hotmail.

I then found Microsoft's Sender ID Framework SPF Record Wizard, which builds a SPF record for your domain.

In Step 1, I entered my domain - gardiner.net.au

In Step 2, it confirmed that A and MX records are available but no SPF record was found.

In Step 3, I checked the following options:

I'm not completely sure that this is correct, but it seems the best choices at first glance. I de-selected the "All addresses listed in A records may send mail" option, as as far as I can tell, the IP addresses in the A records for gardiner.net.au don't resolve back to the email servers.

Step 4 then generates the SPF record, which you copy to the clipboard.

Back in ZoneEdit, you can add a TXT record to contain the SPF data via the Advanced Records heading.

So now, I sit back and wait and see if Hotmail is any happier.

I'd already been in contact with Peter regarding the forthcoming CodeCampSA with some ideas for topics:

Looks like I'll be getting the content for the unit testing talk ready ahead of schedule :-)

Another fantastic article by Billy McCafferty.

This time he goes through all the details of building an ASP.NET project using NHibernate.

This fits in nicely with his other article on using the MVP pattern.

ReSharper 3.0 beta

Tuesday, 5 June 2007

I've read a lot of comments promoting ReSharper as the "must-have" productivity tool for C# developers.

While I do dabble in C#, VB.NET is my bread and butter, and up until now, the only options I've tried are the free Refactor products from Developer Express.

I now see that the next version of ReSharper supports Visual Basic, so it will be interesting to compare the two products to see how they shape up.

One obvious difference is that as far as I can tell, the ReSharper product is only available commercially - eg. no free "lite" version that I can see.

Still, if the tool's as good as people say, then it could be money well spent.
