Hi

My e mails will not send this morning , although I am receiving e mails. 

All sent mails say 'sending' but go straight to Drafts 

In Drafts the e mails cannot be sent and shows a message in a grey box 

Your message will be sent, but we are not quite ready. Please check again in a couple of minutes. 

This is now 3 hours on.

This has never happened before and is happening on 2 separate machines , a desktop and a laptop. 

HELP PLEASE!
