SPF records for draisey.ca

I just added SPF records for my draisey.ca domain. I added a neutral "?all" as the last condition so hopefully my mail delivery wont be any worse than before --- I strangely doubt that however, and cringe to learn I put a one week lifetime on these records --- what was I thinking? Some mail I sent to Japan, through the otherwise reliable Google Apps, seems to be going astray so I was hoping a little added SPF spice might improve its chances of arriving. Fool I am.
