unless it blocks sender verification.

Can you be more specific? what's wrong with this? it's the only
response I or my mta gets.

# dnsmx verizon.net

# telnet relay.verizon.net 25

presumably they are checking envelope from for something (eg
expecting my mx to do something spamd is not doing), because when
I lie about envelope from, I get substantially improved results

# telnet relay.verizon.net 25

221 2.3.0 Bye received. Goodbye.

So my question is, does anybody running spamd deliver to
verizon.net without providing a false envelope from?
What do you do?
