Welcome Banner

You can configure Cisco AsyncOS for Email to display a welcome banner

web interface. You can use the welcome banner to display internal security

New authorization 
protocol for outgoing 
SMTP authentication

Outgoing SMTP authentication now supports the following additional 
authorization protocol: LOGIN.

Enhanced spam

Cisco AsyncOS now has enhanced capabilities to detect and protect against 
new spam campaigns, for example, snowshoe spam.

More flexibility for 
choosing users for an 
incoming or outgoing 
policy

Prior to this release, an incoming or outgoing policy matches if any of the 
specified values (sender, receiver domains, or LDAP group names) in the 
policy matches. 

Cisco AsyncOS 9.0 for Email provides you more flexibility for choosing 
users for an incoming or outgoing policy. You can set the policy to match if,

The message is from any sender, one or more of the specified senders, or 
none of the specified senders.

The message is sent to any recipient, one or more of the specified 
recipients, or all of the specified recipients and none of the specified 
recipients. 

From Cisco AsyncOS 9.0 for Email onwards, you must specify at 
least one sender and recipient.

Enhanced URL 
Defanging

Message and content filters for URL defanging now accounts for DNS 
spoofing and replaces a “.” (dot) in the URL with “[.]”. For example, after 
defanging, www.defangurl.com becomes 
BLOCKEDwww[.]defangurl[.]comBLOCKED. 

The disk_usage 
command has been 
deprecated

The 

disk_usage

 subcommand under 

diagnostics

 has been deprecated. To 

view and configure disk space quotas, use the 

diskquotaconfig

 command 

instead.

Opening a Support 
Case from the 
appliance 

In order to open a support case from the appliance, you will need your CCOID

other means. 

Also, in order to route cases more efficiently, the Technology and 
Sub-Technology options may differ from previous releases and may change 
at any time.
