I’ve mentioned before how I’ve made use of PageMethods with a previous ASP.NET project.

Fabrice has now kindly added me to the developer list for the project, so I hope to be able to contribute to future versions.

I’m not convinced my first attempt at a SPF record worked. I’ve sinced found this SPF Setup Wizard, a nice introduction and also a detailed description of the SPF syntax.

There are also some validators that might be useful:

• SPF Query Tool
• SPF Validation Tool
• SPF Syntax Validator
• SPF/SenderID email test
• Send an email to [email protected]

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:

• Domain’s inbound servers may send mail(and checked both email servers listed)
• All addresses listed in A records may send mail (and checked both IP addresses)
• Discouraged; mail may legitimately originate from IP addresses not identified above, however, use of such IP addresses is discouraged and may not be permitted in the future.
• Scope: Both

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’ve just been asked by Peter Griffith if I could fill in as speaker this month at the Adelaide Dotnet User Group.

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

• Continuous integration with CruiseControl.NET
• Writing a Windows Vista Sidebar Gadget
• Unit testing with MbUnit

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