Good article. I didn't realize there is a cap of 10 lookups. This makes setting up SPF records for people that use Google Apps, blackberries, and web servers that send out emails need to really pay attention to this kind of stuff! I agree that the SPF standard needs some work in order to meet real-world needs.

> I also replaced aspmx.googlemail.com with _spf.google.com which is what it redirects to anyway. Technically, this isn’t a good idea since Google could change it on me

As of July 2010, "include:_spf.google.com" is their official recommendation, cf. http://www.google.com/support/a/bin/answer.py?ans…

(This is for anyone coming later; thank you for the post)

Thanks for this clarification. I’m just getting started with SPF, and I discovered that by merely adding two ESPs (MailChimp and SurveyGizmo), I’ve blown past the limit! This makes SPF ‘not ready for prime time’, a toy unfit for real-world purpose.

(BTW the caret in invisible in Firefox – makes it hard to type).

Thank you for the help. I had the exactly the same problem, I just replaced a few a: references to ip4: references.
