Cisco Cisco Email Security Appliance C380 Notas de publicación

AsyncOS 7.5 includes SMTP call-ahead recipient validation, which allows the 
Email Security appliance to perform recipient validation by querying an external 
SMTP server prior to accepting incoming mail for the recipient. SMTP call-ahead 
recipient validation is useful in cases where you might want to validate users but 
cannot use LDAP Accept or the Recipient Access Table (RAT) for recipient 
validation.

AsyncOS 7.5 include a configuration history log that consists of a configuration 
file with an additional section listing the name of the user, a description of where 
in the configuration the user made changes, and the comment the user entered 
when committing the change. Each time a user commits a change, a new log is 
created containing the configuration file after the change.

With AsyncOS 7.5, you can create some text resources with both HTML-based 
and plain text messages. When the text resource is applied to an email message, 
the HTML-based text resource message is applied to the text/html part of the 
email message, and the plain text resource message is applied to the text/plain part 
of the email message.

To prevent log files on the appliance from becoming too large, AsyncOS 7.5 
performs a “rollover” and archives a log file when it reaches a user-specified 
maximum file size or time interval and creates a new file for incoming log data. 
For example, you can set up the appliance to perform rollovers every night at 
midnight to archive a day’s worth of logs. You can configure rollovers to be 
performed hourly, daily, or on certain days of the week.
