After my 'thank you' post there were
many responses, including one from
Paul N. Lee.  I sent him a personal
e-mail (off the list), which he
received, and he sent me a reply.

When I sent a response that I had
prepared off-line, it bounced, with a
message saying that I was blacklisted.

Any ideas?

Sending this to the list and to Barry....  I have no idea, since I have not seen the source of the bounce, nor the details of that returned email.

All that I can say is, give it another try and seen what happens.  After all, the first personal email came through just fine.


Sincerely,
P.N.L.
