>From spamdyke.org docs:

 

reject-missing-sender-mx Check the domain name of the sender's email address
for a mail exchanger (an MX or an A record). If neither are found, reject
the connection.

 

Maybe you had authenticated for this test, in which case it would be let
through?

 

It definitely works - I see rejections every day, usually for bank phishing
emails from non-existent domains, or from badly configured list servers
where lists.domain.com has no MX record.

Faris, 

it is confirmed that your idea was wrong. I used a fake "mail from" in
telnet, l...@sflie.com. The domain doesn't exist and therefore has no MX
record and still Spamdyke permits the smtp session. 

This looks more and more like a bug to me.
