Please help with email not working, I've tried my best to no avail

[geoffval]

OK first some information:
My primary domain is geoffvalenti.x10.mx
I created a domain geoffvalenti.co.uk to host my website.
The website functions as it should and I can upload changes via ftp.

I've got 2 email accounts
enquiries@geoffvalenti.x10.mx (which works OK)
enquiries@geoffvalenti.co.uk (which worked until migration)

The address enquiries@geoffvalenti.co uk will not send any mail, and only receives mail that I send as tests from the x10.mx address. No other account can send it mail.
I need this account as it's been given to people as a contact address.

I've tried everything that I know. I've followed the details for account servers but nothing seems to work
For info, I'm using the settings
SMTP server name = mail.geoffvalenti.co.uk
Port 587
Connection security SSL/TLS

IMAP server = mail.geoffvalenti.co.uk
Port 993
Connection security STARTTLS
Password same one as webmail (which gets me into the account)

I'd be grateful of some help here.

I can see you are using cloudflares nameservers, have you updated those with the change of IP after the migrations?

Since there isn't any intergration between DA and cloudflare as was present on cPanel any changes has to be updated manually on their end. The IP of your server is: 198.91.81.13

Thank you so much Anna. Everything works fine now.
You're a lifesaver
