I wonder if anybody has any more background to this "ISP encoding corrupting PDFs" ? I work in a technical industry, and we have a lot of different file types flying around via email (source code, binaries, executables, zips, tars etc etc) and the only files we ever have problems with are PDFs. Also this seems to have gotten much worse with the later revisions of Acrobat.
It seems to me that if there was an issue with ISP encoding, then it would affect other file types too.
Any other suggestions would be greatfully received - this PDF issue is driving me nuts!
Thanks in advance,
I agree with Mark. I am using Mac OSX (v10.6), firebox to download some PDF's from FTP sites, and I recieve some PDF's via our company email. Our company email isn't filtered at all (small company).
When I download PDF's from an FTP site, they almost always work. When something is emailed to me (from a Window's computer) they often do not work.
How do we actualy FIX this issue? From what I understand, the error "file is damaged and cannot be reparied" doesn't actually have anything to do with a damaged file, but an incorrect reader. I am using Adobe Reader 9.3.0 (no more updates available.)

I'll look around.
Before they switched these forums over to this software, their USED to be a very informative FAQ area that had a subject on this. I'm not sure where it's gone but there may be a KB article on it somewhere still.
The problem is an old problem due to the way mail is handled. Acrobat pdf files are sometimes treated as if they are ascii files rather than binary files. This causes them to be corrupted as since mail handlers will sometimes handle ascii attachments differently than binary attachments. The work around is to zip or otherwise compress the file so that the attachment will be treated as a binary file. This same problem can occur with ftp as there are binary and ascii upload/download issues. These types of problems are common and go back to the early days of mailing on the internet. uuencoded files were frequently corrupted as well.
