Today we are encountering huge problems with all our emails.

Our basic setup with Zohomail is to use it as a forwarding system and it has been working very well up until today when it stopped sending and receiving mails from our business address.

So at the moment we are forwarding all our business email directly to our own personal gmail accounts.  

Below is my email that i sent to a colleague.

And here is what he received from  mailer-daemon@mail.zoho.com

So essentially we cannot send any mail from our @middleofgrey.com address's.  Before today the system has been working perfectly well for our needs.  We think the problem does not lie with gmail as we have followed these emails in to zoho mail.

Any help would be appreciated.  We thought it might be the footer in our emails but like i said, its all been working fine up until today.

Thanks in advance
