Actually - I finally figured out the problem about twelve hours after
sending the original message.
Apparently, my old ISP gave me a host-name that was 'reverse-lookup-able'
so that any SMTP servers I contacted would trust my Fax server, because
they could reverse-lookup its host name and get an address that matched the
actual IP address of the sending computer. My new ISP does not give me a
'reverse-lookup-able' hostname/IP address combination, so many SMTP servers
would not trust my Fax server, and would not accept E-Mail from it.
The solution was to set the Smart Relay Host parameter in the sendmail.cf
file.
I added the following line to my sendmail.cf, and the problem was solved:
DSsmtp.myisp.com
