Currently I have a couple of users who send large files (MPG/AVI) via email. These are usually fine, as they are sending to locations that accept large file sizes, but on some occasions they get rejected.
The mail then bounces back and clogs their inbox, as it appears to almost double in size - I think this is because the attachment is no longer kept as an attachment, but put 'inline'.
Can anyone suggest how to filter out these messages on the server?
