I've been doing what testing I could and I think that the third test on my
validator page, "Test an SPF record":
http://www.kitterman.com/spf/validate.html
will work properly with all the SPF record macros, but since I don't have
any macros in my records, it's difficult for me to test thoroughly. If any
of you who have macros in your SPF records would take a moment to try it out
and let me know what you find, I'd appreciate it.
I'm tempted to take off the note that says it doesn't support macros, but
I'd appreciate some additional testing first.
Thanks,
Scott K
