Not all servers are currently checking SPF and there is no way to force 
them to do so. All you can do is canvass the mail admins and evangelise 
the SPF concept.

That said - it is my personal experience that there is currently a 
significant number of servers that are checking SPF and once you 
implement an SPF record it quickly stops being viable for the spammers 
to spoof your domain.

It usually takes about 2-4 weeks for the spammers to realise that they 
are getting high numbers of rejections from a specific domain and they 
then remove you from their database.
