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?
