I recently used "Reply" instead of "Reply List" to attempt a private
reply. That attempted to send to the list anyway, but I didn't notice.
That lead to three days of "delivery delayed", and finally to "Delivery
Status Notification (Failure)", with this reason given:
554 5.7.1 Service unavailable; Client host [209.85.160.47] blocked using
dnsbl.sorbs.net; Currently Sending Spam See:
http://www.sorbs.net/lookup.shtml?209.85.160.47
So, here's me now, testing whether I can reply to the list at all.
