I have a subscriber who has been receiving posts out of order of their being posted, and some not received at all
In his Email delivery history under Most Recent Unsuccessful Attempts of which there are about 20 , this is the response message :-
mx2c51.megamailservers.eu: 452 4.7.1 Your IP address has been temporarily deferred. Please retry this message later. H:GRM
And under Bounces :-
mx4c51.megamailservers.eu: 452 4.7.1 Your IP address has been temporarily deferred. Please retry this message later. H:GRM
Am I correct in saying that this is a problem at the subscribers end?
