Did you set the times to the latest document?
Do you have a populated exceptions list?
Note the BLOCK PERIOD is set to 1 MINUTE
Everyone whose an MX server should be retrying now. We see AOL, COMCAST, GMAIL and all of the other "prior offenders" now retrying several times per minute.
Did you also check your SMTP and DELIVERY logs to see if there are any other issues with the sending domains?
We've found delayed/non delivery issues caused when a sender has multiple MX servers and one, or more, of them are not "available."
While that should not be causing issues, and messages should be automatically retried by senders, we both know that there are still many who are not in compliance.
