Greetings,

I have several users reporting that PDF attachments are coming in
corrupted. They are using either thunderbird or outlook on windows xp.
I have flushed the cache files for the users, but the problem still
persists. Could anyone offer some troubleshooting tips?

Thanks in advance for any assistance.

Below is my version and config.

Regards,

Mike
