I can not send email from zoho, but I can receive !

I just moved from GoDaddy to zoho and while I could send emails this morning, any mails to my work mail do no seem to be received.
I've been testing all day and sending mail to gmail as well as my work email and gmail receives email fine but it is not received at all by xxx@bxxxxxxbrick.com  [which is my work mail].

Please can you view my profile and settings and advise.
