We run Exchange 2010 and we have Symantec's Messagelabs as our spam and email policy controller. I've set a limit of 10MB for attachments coming inbound and for them to be deleted.
However, the issue is that then you create the problem of that email being blocked, then the users need to get in touch to ask why/what has happened, which they come to us for and we have to begin asking questions and then find out 'aha..it was because the image size was too big'.
Are there better ways to manage it? For example, to have the inbound email to go into a mailbox that we can monitor which we release the content?
Do you have any strategies that you use?
