mail delivery deferred - exceeded 250 messages/hour InMotionFans 6 years ago Answered If delivery is deferred, do you receive a message when the delivery is reattempted later? In other words, how do I know if the deferred emails eventually get delivered? Thank you.
Thank you for submitting a question regarding mail deferral. The server will continue to send the mail at intervals to allow other messages through. There's no way to know until the process finishes how many will ultimately arrive. Were you sending out a large email campaign or a message to an email list that exceeded a hundred or more addresses?
