Cisco Cisco Email Security Appliance C670 릴리즈 노트

The appliance more efficiently clears out memory used by messages exceeding the 
maximum allowed size. In addition, the order of the log lines have changed to ensure 
that oversized messages are always logged.

Previously, if you attempted to update an existing certificate in the CLI with a public 
certificate that did not match the private key, the CLI correctly displayed an error 
message but incorrectly displayed the invalid certificate in the list of the appliance’s 
certificates. If you made any other changes without exiting the 

certconfig

 command, 

the system committed the invalid certificate and an application fault would occur the 
next time you ran the 

certconfig

 command. This issue has been resolved.

Previously, when using the z= tag with DKIM signing, multiple recipients could cause 
the DKIM header to exceed the maximum length allowed by SMTP RFC. This could 
cause delivery issues. This issue has been resolved. The z= tag is now turned off by 
default.

Previously, when RSA Email DLP scanned a multipart/alternative type message, such 
as HTML messages with a alternative/plain text part, the system combined the 
classifier scores of both parts of the message to create the DLP score. This could result 
in a message that should have a “low severity” score to be rated as high or medium 
severity. This issue has been resolved.

Fixed an issue where a message cannot be encrypted if its From header is split over 
two lines.

72708

Fixed an issue where the Email Scanning Engine would crash when attempting to 
process malformed UTF-32 payloads.
