I have added in a custom mime type (epub) as "application/epub" into IIS7.

This was working originally but something seems to have stopped it working and now we get the response "403 Forbidden: body content-type denied".

This is a strange message, and google brings up very few results, none of them seem relevant.

Any ideas?

I spoke to our IT admin and we figured out that it was the firewall that was blocking the request.

More detail would be helpful to the next person who encounters this issue (what firewall software? what settings needed to be changed, etc.) – voretaq7 Sep 4 '12 at 16:38
It's a firebox 550e. The solution according to our IT guy was: "dont try and block any attachments that are downloadable". I'm not sure of the exact settings. – Hainesy Sep 5 '12 at 8:14
