when it processes emails and the Cisco Anti−Spam Engine (CASE) is unable to scan them.
Problem
The ESA processes emails that the CASE is unable to scan, and the ESA presents this notification:
The Critical message is:
MID 124578 cannot be scanned by CASE. The message is either
malformed or CASE is unable to process it at the moment.
Solution
This notification is caused by a corrupted email that has bad base64 encoding, or has corrupted Multi−Purpose
Internet Mail Extensions (MIME) parts, and cannot be scanned properly by the CASE. The CASE itself works
as designed, and this is not an indication of an overall processing issue on the appliance.
