Is this for some, or all, PDFs? A common problem with dealing with attachments is when they're sent using the wrong mime-type. Files are supposed to be sent with a description of what type of file they are, and the recipient is supposed to act upon that information. It's not supposed to guess from the filename, nor snoop into the file to work it out. PDFs ought to be sent as: application/pdf However some senders may be set up badly, and just use the generic "application/binary-octet" that means some unknown binary file.
