I occasionally send email to relatives in Paris. Often the mail does not go through and I don’t get notices of this non-delivery for days after. Apparently their provider, free.fr, is blacklisting the Verizon Online IP 206.46.173.21 for too much spam (certainly not mine!). What can I do to prevent this inconvenience?
