Release Notes for Cisco IronPort AsyncOS 7.6.1 for Email
Known Issues
76940 Using IronPort Mail Merge Variables in a Message May Prevent DKIM Signing
Using IronPort Mail Merge (IPMM) variables for outgoing messages may invalidate
the DKIM signature for any signed messages that are altered by IPMM. IPMM is only
used on C300D, C350D, C360D, and C370D appliances.
77059 Messages Altered by AsyncOS are Unscannable by Sophos
AsyncOS sometimes cleans bare CR and LF characters from messages, which results
in Sophos flagging the messages as unscannable.
77609 Active Sessions Page and who CLI Command Cannot Display Active CLI
Usernames 16 Characters or Longer
Neither the
who CLI command nor the Active Sessions page in the GUI can identify
active CLI users with usernames 16 characters or longer.
68899 Sophos Anti-Virus Unable to Scan PDFs with Large Cross-Reference Tables
The most recent Sophos anti-virus scanning engine imposes a maximum limit to the
number of entries in a PDF’s cross-reference tables to avoid malformed files from
using too much memory. The scanning engine returns “unscannable” for PDFs that
exceed the maximum limit even if they are not malformed. Cisco IronPort is working
with Sophos to resolve this issue in a future Sophos engine update.
68368 Reconnect Link in GUI Does Not Reconnect Machines
The “reconnect” link in the GUI does not reconnect machines that were disconnected
from a cluster unless the machines were disconnected from the cluster individually.
Workaround: Use the
clusterconfig -> reconnect command in the CLI to
reconnect the machines.
68556 Renaming Encryption Profile Doesn’t Update DLP Policy
If you rename an encryption profile that is being used by a DLP policy, AsyncOS does
not automatically update the DLP policy with the updated encryption profile name.
AsyncOS will bounce messages that match the DLP profile.
69838 LDAP Doesn’t Renew Connection After Certificate is Removed from Appliance
The Email Security appliance does not renew its connection to the LDAP server if the
security certificate assigned to the LDAP interface is removed from the appliance
after the connection was established. Workaround: Reboot the Email Security
appliance to release the connection.
71854 Reboot Required to Show Message Tracking Data After resetconfig
No results are shown in Message Tracking after running
resetconfig on an Email
Security appliance running AsyncOS 7.6 for Email and using
loadconfig to load a
configuration file. To work around this issue, reboot the appliance. All message
tracking details will appear correctly after the reboot.
51960 The Email Security Monitor Overview Page Incorrectly Counts Quarantine
Mails as “Virus.”
When calculating the number of virus-positive messages, the Email Security Monitor
Overview page includes messages that were quarantined by the anti-virus scanning
engine due to the message being unscannable or encrypted. These messages are not
included in the virus-positive report on the Virus Types pages.
