Release Notes for AsyncOS 9.8 for Cisco Email Security Appliances
 
  Changes in Behavior
Changes in Behavior
Marketing Email Settings
If you had enabled anti-spam scanning and had configured Marketing 
Email Settings under anti-spam settings for a mail policy, after upgrading 
to AsyncOS 9.8 or later, 
Graymail will be enabled globally by default. 
Marketing Email Settings under anti-spam settings will be moved 
under graymail settings of the same policy. 
While using graymail-related reports, keep in mind that:
The number of marketing messages is a sum of marketing 
messages detected before and after the upgrade.
The total number of graymail messages does not include the 
number of marketing messages detected before the upgrade.
The total number of attempted messages also includes the number 
of marketing messages detected before the upgrade.
Content Dictionary 
Changes
For efficient processing, the following content dictionary entries are 
treated as words:
Entries containing only alphanumeric characters
Email addresses containing the following characters: 0-9, A-Z, a-z, 
dot, underscore, hyphen, and at symbol
Domain names containing the following characters: 0-9, A-Z, a-z, dot, 
underscore, hyphen, and at symbol
If you want the appliance to treat such a word as a regular expression, 
enclose the word in parenthesis, for example, 
(user@example.com)
.
File Analysis 
File Analysis changes may require action from you. See 
DKIM Signing-related 
Logging Changes 
If the log level is set to Trace, the mail log will now include additional 
log entries to identify errors that occur during the DKIM signing 
process. 
The mail log will now include two separate log entries for DKIM 
signing: one for displaying the signing profile that will be used for the 
signing and the other for the signing event.
AMP-related Mail Log 
and Message Tracking 
Changes
Prior to this release, if the threat verdict of a file is unknown, the verdict 
was shown as “clean” in the mail log and message tracking. 
After upgrading to this release, if the threat verdict of a file is unknown, 
the mail log and message tracking will show the verdict as “unknown.”
Graymail Changes 
Prior to this release, if a message is graymail and outbreak filter positive, 
the actions configured for graymail are not applied after the message is 
released from the outbreak quarantine. The safe unsubscribe banner (if 
configured) is not added in this scenario.
After upgrading to this release, the actions configured for graymail are 
applied after the message is released from the outbreak quarantine. The 
safe unsubscribe banner (if configured) is added in this scenario.
