Примечания к выпуску для Cisco Cisco Email Security Appliance C160

Upgrade Request of Second Level TDLs (Regional Domains). In the previous release, 
subdomains would not be listed in the Sender Profile section of regional domains on the Incoming 
Mail report. The same applied while searching for Regional domains. Example: "foo.mail.ru" will 
not be listed in the Sender Profile report for mail.ru.

Email Sent to Recipient with Only Periods in Domain Name Halts Message Processing. 
Previously, if the Email Security appliance received an email sent to a recipient with only periods 
for the recipient’s domain name (e.g., bob@......), the email would result in the Email Security 
appliance halting message processing. The appliance would continue to accept messages, but could 
not process them.

IronPort Mail Merge Feature Missing. Previously, 3xxD appliances upgraded to AsyncOS 7.5.0 
or later lost the IronPort Mail Merge (IPMM) feature. Previously, appliances with a DPP feature key 
received the IPMM feature, too. This issue has been resolved. Appliances with a DPP feature key 
once again get the IPMM feature.

Changing Notification Schedule Sends Out Notification. Fixed an issue where changing an email 
notification schedule results in the Email Security appliance automatically sends out email 
notifications once you commit the change.

Upgrading to AsyncOS 7.6.0 Changes Netmasks of IP Interfaces on a Single Physical Interface. 
If you have assigned multiple IP interfaces with the same 255.255.255.0 netmask to a single physical 
interface, the Email Security appliance would automatically assign a netmask of 255.255.255.255 
to one of the IP interfaces, making the other IP interface the source of all requests from the physical 
interface. Upgrading your appliance to AsyncOS 7.6.0 may have swapped the netmasks for those 
two interfaces, which could result in connection problems, depending on your configuration. This 
issue has been resolved. Upgrading to AsyncOS 7.6.1 does not change the netmasks of the IP 
interfaces.

Application Fault Occurs When Viewing Report on Incoming Messages with No Hostname. 
Fixed an issue where viewing an Incoming Mail report on messages from an IP address with no 
domain record could result in an application error.

LDAP Using Invalid Interface on Clustered Machine Causes Application Fault. Fixed an issue 
where if you change the name of an interface on a clustered machine, opening the System 
Administration > LDAP page in clustered mode would cause an application fault.

HAT Rescanning May Cause Application Fault if the Connection is Refused at TCP Level. 
Fixed an issue where a the HAT rescanning feature may cause an application fault to occur on the 
appliance if, upon rescanning, the message’s sender is moved to another sender group that has 
Directory Harvest Attack Prevention limits set and will refuse a connection at the TCP level.

Adding Footer to Uuencoded Messages Results in Outlook Rendering Messages Incorrectly. 
Fixed an issue where adding a footer to a uuencoded message would result in Outlook displaying 
the message incorrectly by rendering its attachments inline. This was due to a MIME-version header 
being added to the message because of the footer. This issue has been resolved. Adding a footer no 
longer adds a MIME-version header to the uuencoded message.

Signing a Splintered Message Relayed Through Private Listener with DKIM Could Result in 
Dropped Message. If you have configured a private listener on the appliance to sign a message 
using DKIM, it was possible in previous versions of AsyncOS that the appliance may not have 
delivered one of the messages if the original message was splintered. This would result in one of the 
splintered messages in being lost.

Injection Debug Log with Syslog Push Retrieval Method May Cause Work Queue to Crash. 
Fixed an error where an injection debug log with Syslog Push as a retrieval method could cause the 
appliance’s work queue to crash when work queue processing is restarted.
