I am one of people supporting these mailinglists, and acting as
one of assisting postmasters.
Quite often I see things like what this summary report tells:
<smtp cedar-republic.com [email protected] 60000>: ...\
<<- RCPT To:<[email protected]>
->> 550 <[email protected]>... we do not relay

Yields information that ONE of their backup MX servers refuses
to send email thru to them. Thus whenever all other servers
fail to be reachable, that one ruins their email connectivity.
Do make sure YOU don't have this very problem!
