Mail Policy Matching 
Logic Changes

Prior to this release, while matching a message to a mail policy, the 
envelope sender (RFC821 MAIL FROM address) and the sender header 
(address found in the RFC822 From and Reply-To) had the same priority. 
As a result, if you had configured a mail policy to match a specific user, 
the messages were classified into that mail policy based on the sender 
header.

After upgrading to this release, when you match a message to a mail 
policy, the envelope sender and the envelope recipient have a higher 
priority over the sender header. If you configure a mail policy to match a 
specific user, then the messages are automatically classified into the mail 
policy based on the envelope sender and the envelope recipient.

Miscellaneous Disk Usage  After upgrading to this release, when Miscellaneous disk usage reaches 75 

percent of the quota, the appliance immediately recalculates the disk usage 
to ensure that the usage has actually reached 75 percent and adds the 
following entry to the Mail Logs at Debug level: 

Disk quota for 

Miscellaneous services (logs, configuration file, and so on) is 

reaching its limit. Recomputing disk usage to double-check disk 

quota

. After the recalculation, if the disk usage has reached 75 percent, an 

alert is sent. 

This process is repeated when Miscellaneous disk usage reaches 100 
percent of the quota.

New Alert for Message 
Filter Crashes 

When a message filter crashes, the appliance sends a system alert with a 
critical severity.

Password to Passphrase 
Change

The term “password” is changed to “passphrase” in web interface and 
command line interface.
