Cisco Cisco Email Security Appliance C690 User Guide

If, however, the user accesses the quarantine directly via a notification, or if the 
authentication method is IMAP/POP, the quarantine will only display messages 
for that user’s email address (or the address to which the notification was sent). 
For more information about how end user authentication works, see 

Keep in mind that email addresses are case insensitive in the IronPort Spam 
Quarantine, so for example, email for Admin@example.com and 
admin@example.com will both be present in the quarantine for a user associated 
with “admin@example.com.”

You can use multiple mail policies (Mail Policies > Incoming Mail Policy) to 
specify a list of recipient addresses for which mail will not be quarantined. Select 
‘Deliver’ or ‘Drop’ instead of quarantine when configuring the anti-spam settings 
for the mail policy.

AsyncOS attempts to determine the charset of a message based on the encoding 
specified in the message headers. However, if the encoding specified in the 
headers does not match that of the actual text, the message will not be displayed 
properly when viewed in the IronPort Spam quarantine. This situation is more 
likely to occur with spam messages.

In the case where incoming email does not have a charset encoding specified in 
the headers, you can configure your Cisco IronPort appliance to specify a default 
encoding. Doing so will help ensure that these types of messages display properly 
in the IronPort Spam quarantine.

However, specifying a default encoding can cause messages in other charsets to 
display incorrectly. This applies only to messages that do not specify the encoding 
in the message headers. Generally, you would only want to set a default encoding 
if you expect the majority of your mail that falls into this category to be of one 
specific encoding. For example, if the majority of your mail that gets quarantined 
and that does not specify the charset encoding in the message headers is in 
Japanese (ISO-2022-JP), you would select option 12 (in the
