Release Notes for Cisco IronPort AsyncOS 7.6.1 for Email
What’s New in Cisco IronPort AsyncOS 7.6.1 for Email
80566 Fixed: 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.
84294 Fixed: 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.
84638 Fixed: 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.
84199 Fixed: 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. This issue has been resolved.
84189 Fixed: 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.
84656 Fixed: 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.
