I have a firebox 750e that keeps deleting this particular pdf. I can get other pdfs so it is not a file type issue. Additionally the sender is known and trusted.  Here is the message:
The WatchGuard Firebox which protects your network detected a message which may not be safe.

Cause : The message content may not be safe.
Content type : application
File name    : Rimrock Resolutions.PDF
Virus status : No information.
Action       : The Firebox deleted Rimrock Resolutions.PDF.

Your network administrator can not restore this attachment.

You must be using SMTP or HTTP proxy; by default the proxy service would deny many of the attachments, hence the problem.

In Policy Manager, edit the specific service, go to Properties tab; click View/Edit Proxy button, go to Content Types; here add "application/*" from Predefined.

Please note if you do not want to allow this content type for all users, then you must add another proxy service to allow traffic specifically from this sendor, configure to allow content type, configure service as below:
Enabled and Allowed; from public-ip-of-client; to NAT-as-configured-in-original-service

Thank you.

Thanks. I am using an SMTP proxy. I have the application type application/*pdf allowed. That should do it right? I am not sure if I want to add application/* wont that allow all?

application/*pdf allows all content type of *pdf belonging to application category; what firebox is reading here is;
>>Content type : application

So we would need to allow application/*

You are correct this is a security risk; either ask the user to encode the file using some other application so the content type is correctly understood by the firebox; OR as the user is trusted, create another SMTP proxy service as I detailed, now only for this specific user you allow application/* using new service all other traffic is screened using the current/existing SMTP service.

Thank you.

I have asked the user to send as a zip. That was my first solution but what I don't get is normally the message will say specifically what application or mime type was blocked and I would use that to make my exception, this time it did not... Wonder why?

Thanks for your suggestions -M
