I have observed that messages from our system are temporarily rejected as greylisted by one destination but they are never accepted on retry. The response is logged as "DATA: 451 0.0.0 1 recipients being greylisted for 5 minutes". We retry after 10 minutes and get the same response.
Normally I would expect the retries to pass greylisting. Does anyone have any insight into why this is not behaving as expected? The destination is exeter.ac.uk.
