I don't use one of the free hosts, but do use a hosting service.
I saw a lot of replies to messages from Bill Whitlock, but never saw any
original messages from Bill. Would bounces due to tightened security
settings on the mail be likely?
I am having trouble finding details of the current configuration for my
hosting service, the overview page lists SPF, but does not say whether
that just means they set SPF properly on the outgoing messages, or also
check  on incoming messages.
