Hmm, I hadn't thought of that. I haven't seen it fail that way
yet. Still, the callout will fail and their mail won't be accepted
which is no different to the current situation except that the
number of FP callout rejections is reduced. If I can't at least
verify that you would accept mail from me in return, I won't accept
from you. Maybe that's too bloody minded and I'll be subdued by
time and experience.
