I'm not in favor of MS SenderID reusing SPF records. I signed the statement
to that effect too. What are we supposed to do with SID and PRA? There is
no good answer. In 95% of cases whatever advice we give for SPF will work
out OK for SID too. What do we, as a community, want to do with the 5%?
Personally, I'm not going to work very hard on figuring out PRA unless
someone is paying my consulting rates to get my attention. I just do my
best to ignore it because I don't think it's going to catch on. I do think
though that if I give advice that I know will work for SPF, but fail for PRA
I ought to at least warn them and tell them how to deal with it. I don't
think it's fair not to warn people.
There's no mystery any more about is MS going to hijack SPF records. I
really think that the appeal needs to be filed and we need to be on record
opposing what they are doing. I also don't think that any appeal or
argument we make is going to get them to stop. I think it's unfair of us
not to warn people when we can.
I expect this will be controversial. Before anyone flames me in response
please note that nowhere in here have I in any way praised SID.
