my mta works thank you very much.

I inquired if anybody else was getting deferral from verizon
perpetually and what they do about it---I get 450 for 7 days,
then my mta gives up and returns the message.

there are so many google hits on this verizon problem it's hard to
get the good info, this list is by verizon.

1.) Please ensure that your server is accepting mail from

2.) Please ensure that your server accepts a Null Mail From: command
e.g. Mail From:<>.

3.) Please ensure your mail server responds to the SMTP commands within
30 seconds.

4.) Please ensure the from address used is a valid email address that is
accepted by the MX server for that domain.

5.) Please ensure you have a proper MX record.

if you must conform to all these, to send mail, that's not rfc
2821, nor is a 450 message for over 5 days.
