spf and gmail

Dear All,

We have published our spf record. By spf testing tool, it shows working fine. But when i send a mail with my
domain which is not generated from autorized server, the gmail accept. By checking full header in gmail,
it shows hardfail etc.. So, if gmail has adpoted spf checking and the domain who has published spf why gmail
is accepting mail ? What is the reason ?
