This does not seem a global problem: The error message "450 4.7.1"
does not indicate a permanent failure (those start are 5xx) but a
temporary failure.[1]  Moreover the message states "Client host rejected",
that is: It's the sending client that is not (yet?) accepted.

"S25R check": S25R is a spam protection system which according to it's
page[2] (found by I quick search) states:

,----
| Rejects receiving mail from a host supposed to be an end-user's
| compter based on its reverse name returning a retry request (response
| code "450").
`----

So it's seems to be kind of "greylisting": I assume the "be patient"
tells us, that it will permit the mail in future.

Qmail saying:
>Giving up on 210.228.157.123.
>I'm not going to try again; this message has been in the queue too long.

How long the has the message been it qmail's queue?
