My client is using Zentyal 4.1 Commercial.
A client of theirs is sending email attachments of automatically generated jpg files with 88 character filenames. The email bounces back to the sender with the following message:
BANNED CONTENTS ALERT

What do I need to do to allow this filename, or does the sender need to change the name?
