Release Notes for AsyncOS 9.8 for Cisco Email Security Appliances
 
  What’s New
Cloudmark Anti-spam 
Engine Update
The Cloudmark anti-spam engine is updated in this release.
Non-Spam Quarantines 
You can now specify a retention time in minutes for all policy, virus, and 
outbreak quarantines including the File Analysis quarantine. 
LDAP 
LDAP queries that return certain error codes such as Unavailable, Busy, or 
Operations Error, now fall back to a subsequent LDAP server listed for 
failover. Previously, failover occurred only if the connection to the LDAP 
server failed.
Option to accept or reject 
ARP replies with a 
multicast address
While configuring ethernet media settings using the 
etherconfig
 
command in CLI, you can now specify whether to accept or reject ARP 
replies with a multicast address.
Support for RAR 5.0 
Archive Format
Cisco Email Security appliance now supports scanning of RAR 5.0 files.
Changes in SMTP 
Call-Ahead Server Profile 
Settings
While setting up an SMTP Call-Ahead Server Profile, you can now 
configure the appliance to reject a connection with custom SMTP response 
(code and text) for validation failures.
Using From Header for 
DKIM Signing
You can now use the DKIM Global Settings (Mail Policies > Signing 
Profiles
) to choose whether to use From header for DKIM signing. For 
DMARC verification of DKIM signed messages, you must use the From 
header during DKIM signing.
Duplicate Boundaries 
Verification
Cisco Email Security appliance can now detect messages with duplicate 
MIME boundaries and perform actions on them. 
Use the Duplicate Boundaries Verification content filter condition or the 
duplicate_boundaries
 message filter rule to detect messages with 
duplicate MIME boundaries.
Message Filter Rule to 
Detect Malformed MIME 
Headers(CSCuw03606)
You can now take actions on messages with malformed MIME headers 
using the new message filter rule: “
malformed-header
.” 
See the “Using Message Filters to Enforce Email Policies” chapter in the 
user guide or online help.
