If your mailbox is located at or relayed by any of these domains:
att.net btinternet.com estesvalley.net free.fr icloud.com laposte.net mac.com n5kh.org stpetebeach.net thbt.fr
you may not have been getting some or all 44net email messages over the past few days. What seems to have happened is that the mailing list host, 'mailman.ampr.org', somehow got on somebody's spam list, and some or all of the above domains started rejecting deliveries from it.
Since it is often difficult and time-consuming to get back off such a list, I've implemented a workaround for these domains that should restore deliveries for you folks.
