Cisco Cisco Email Security Appliance C370D

With AsyncOS 7.5, you can now access log files at any time by clicking a link to 
the log directory on the Log Subscriptions page, then clicking the log file to 
access. Depending on your browser, you can view the file in a browser window or 
open or save it as a text file. This method uses the HTTP(S) protocol and is the 
default retrieval method.

The Email Security appliance now automatically updates to the following 
services:

IronPort Anti-Spam and Intelligent Multi-Scan rules

Sophos anti-virus definitions

Time zone updates

You can manage the update settings using the Service Updates page. 

If your organization’s network uses reverse proxy servers between remote users’ 
machines and the Email Security appliance, AsyncOS 7.5 allows you create an 
access list with the IP addresses of the proxies that can connect to the appliance.

In AsyncOS 7.5, you can specify how long a user can be logged into the Email 
Security appliance’s Web UI before AsyncOS logs the user out due to inactivity. 
This Web UI session timeout applies to all users, including admin, and it is used 
for both HTTP and HTTPS sessions. 

The Web UI Session Timeout does not apply to IronPort Spam Quarantine 
sessions.
