Email upload documents not working

Email upload documents not working

Hi

I'm trying to upload documents to the project via email. I'm using the email address supplied by Zoho Projects, [business]_[project]@documents.zohoprojects.com, but nothing is coming through to the Documents tab.

I've tried sending it from different email addresses, but nothing is coming through. There's no email notification to say that a document has been uploaded either.

I need to get this working as it will be a major part of the projects we do.
