Incoming and outgoing emails fail

Incoming and outgoing emails fail

Hi incoming and outgoing emails on peter@border-contracts.co.uk and prsimmo@gmail.com stopped around 9.30 am GMT today. 

A third email account daphnediggins@gmail.com appears to be working ok.

When sending, on the first attempt I get "Unable to connectSMTP server :smtp.border-contracts.co.uk
On the second attempt I the email goes to "Templates"

I can get at my emails via Gandi Roundcube Webmail, but of course they look very basic when sending, not suitable for business.

Many thanks
Peter Simmond
