I am requesting there be included an option to disable senderID, or if you like to enable only SPF (v1)
The main reason for using SPF is to reject forgers, and SenderID protocol is incredibly broken when it comes to dealing with mailing lists, SPF v1 handles these fine, this would allow those of us wanting to do what SPF is intended to do, IOW, use r2 option etc to outright block, can do so without losing legitimate mail, after much google research, senderID recommends violating smtp RFCs to overcome this, this is very wrong, so a simple option allowing us control would be better, perhaps, for example it can do by default as it does now, unless we give a -1 indicating only do SPFv1, and -2 for only do SenderID.
EG- would overcome this :
