Did we have problems on 24th July

Our valued customer Steve Rogerson says he had multiple incoming emails delayed on 24th July - did we have a known problem on that day? That would have caused retry bounces to be sent? This was on domain mcr1.poptel.org.uk

I’m very happy to get back to Steve saying “no problems here that we know of, so I’ve drawn a blank on why your emails were delayed” - if that’s true.

Not sure why this topic seems to disappear from the lists?
