Having the website fixed is unlikely. I changed the SPF record as suggested, but I'm wondering which advantages I have in specifying "v=spf1 a mx ~all" instead of "v=spf1 a mx ?all". I think those problems (ant the fact that having them fixed is extremely unlikely) come mostly from the radical monoculture in end users email providers: if your (broken) system works with gmail you have ~90% of the users covered and you do not care much about the others...
