IMHO sending to postmaster is more reliable an probably more likely to 
achieve the desired effect of having a PermError corrected.

Do you still use DSN format? It may make sense to try and standardize 
the format and the circumstances where such notes may be issued, so 
that postmasters may process automatically some of that.

Would it make sense to cache a domain-name+spf-record-content key, in 
order to avoid sending the same note note than once?
