Is this likely to be my end, as I've not made any changes recently, or something at County's end?

 

Many Thanks, TomHD

There's header analyzers available to make these easier to read: Email Header Analyzer, RFC822 Parser - MxToolbox

 

From the look at it, it looks like it's not make attempt to get past svr-app625.gfl.suffolk.org.uk - so as long as your smtp service is running and you can telnet to it with a EHLO response It's more likely to be them? Does your mail log at the server connecting to the county show any failures in the message tracking?

[TomHD]

Thanks @Domino, all the tests I have performed on my end come back positive

 

I was just on the phone to county (on hold!) when a load of external emails came in so I'm guessing someone else has been on the phone to them already.

 

Tom.
