I tried setting both the IMC Message Size Limit under the "General" tab, and the Outgoing Message Size Limit for a particular user on the user's "limits" tab in order to restrict the size of attachments leaving the network. However, in both cases the limit is only being applied to the message (body) itself and has no affect on the size of attachments. So, if I attach a 50K file and the restriction is 10K as long as the message text itself is less than 10K it goes through. Any thoughts? Thanks.
