Hi Andy Smith,

I see many Andys replying here.

Yes I have at last realised this, from the other Andy's reply. In effect the mailservers are following the Cname in the Bitfolk servers zone, so they will not be looking for the shorter address. It makes perfect sense now. What really puzzled me is that the zone file has sat like that for a number of years just changing a little as it was added to, the old serial number was from one of the later additions. Thank you for your time. That example zone file you linked to is something I had obviously forgotten over the years

Andy,

You sir are a scholar and a gentleman of the highest order.
I made the changes you suggested and here is the result

35.35-32.84.119.85.in-addr.arpa. 600 IN PTR keynesmail.com.

My new zonefile:-

$ttl 600
; $ORIGIN 35-32.84.119.85.in-addr.arpa.
35-32.84.119.85.in-addr.arpa. IN SOA ns3.keiths-place.co.uk. keithwilliamsnp.gmail.com. (
2022041211
600
300
1200
900 )
NS ns3.keiths-place.co.uk.
NS ns2.keiths.place.co.uk.
NS ns1.keiths-place.co.uk.
35.35-32.84.119.85.in-addr.arpa. IN PTR keynesmail.com.

I will now return the TTLs etc to a more sensible number, and all will be set.

Thanks so much for the help, everyone.
Keith
