email_support Posted February 11, 2011 Share Posted February 11, 2011 We are aware of an issue with some inbound mail deliveries receiving 451 soft rejects. Mail which was rejected with a 451 should be requeued and resent by the sending mailserver. 4xx replies are a standard part of the SMTP protocol and specifically used when an inbound mail server is having issues accepting mail. The problem is being worked on and should be resolved soon. Thanks for your patience. Link to comment Share on other sites More sharing options...
