After further investigation with my mailhost (Bluehost.com)
Bluehost IS accepting mail on port 26 in acknowledgement of ISP's
blocking port 25.
I've tested this and it is working for me. FYI.

Hmmmm I too have Verizon and send mail to my own mailhost. I just tried
sending to port 587 on my
host and it did not work. However, I do know that known services such as
hotmail DO accept mail
on port 587.
Paul, how did you hear of this news?

I feel silly asking this question, since I've been working with Linux
for over 15 years. But I've just never had to deal with the issue
before.
Verizon FiOS (which I have) is, starting 8 June, going to block port 25
for customers who don't use Verizon's mail servers (which I don't).
Their alternate port is port 587. As I understand it, I'm supposed to
change my settings to this port, and all will be cosmic.
Here's the thing, though. I tender mail to my local mailserver, which
connects to my internet mailhost via port 25. If I set my local
mailserver to connect via port 587, I can see how this would avoid
Verizon's port blocking. But my internet mailhost still wants to see a
connection on port 25. So does Verizon, when it sees a connection via
port 587 to an internet mailhost, then change the port to port 25 (which
is what my internet mailhost wants)?
Can someone explain how this works?
