Email not getting through

[#1]

Ever since I got the free domain from Plusnet for some reason if I have mail sent to azagoth@mydomain.co.uk instead of azagoth@azagoth.plus.com it doesn't get through. 
This has caused me no end of problems now, with conformation messages not getting through, online receipts not arriving etc.
How do I fix this?

I've given things a nudge from here, occasionally the records for mail on the domain aren't created correctly and need a kick. Can you try again in around 4 hours and this should work.

Many thanks.  I've just sent myself a few test mails via my googlemail and yahoo accounts and they seemed to come through just fine.
Thanks.
