Domain disabled

 Hi,

I've set up two MX records to point to Zoho for firstcapitalfactors.co.uk and all works fine. A day later I got this email:-

Dear Admin,

Mail Domain firstcapitalfactors.co.uk has been disabled by our MXLookup-Task Reason : MX not configured properly Implications : Mails may not be fetched in your users Zoho Account Current MX Records : mailserver.firstcapitalfactors.co.uk. [213.171.216.65, ] | Valid Zoho MX Records : mx.zohomail.com.[72.5.230.114, ] | mx2.zohomail.com.[72.5.230.119, ] | mx3.zohomail.com.[74.201.155.79, ] | 

I've just sent a test mail, and that's got through - what is not configured properly please?
