Adjusts default configuration to improve performance stability on Dell
Email PowerEdge 2950 platforms. (Low severity. Reference: KB81339.) Amends NTP system test so that it does not show misleading error messages when all NTP servers are local. (Low severity. Reference: KB80067.) Addresses a problem with the Intelligent Platform Management Interface (IPMI) on Dell PE1950 hardware which caused intermittent symptoms including slow bootup, failure to display the hardware status, and failure in remote access card configuration. (Low severity. Reference: PD24844. Supersedes: 7.5h965187, 7.5h968383.) Amends the interface with McAfee Quarantine Manager (MQM) so that quarantined email attachments are named correctly. (Low severity. Reference: KB78689.) Correct a fault which, when logical virtual hosting was enabled and configuration was pushed from another appliance, caused the domain given in the SMTP EHLO command to be that of the other appliance rather than the correct virtual domain. (Low severity. Reference: KB79456.) Corrects the handling of email delivery in cases where the policy specifies encrypted delivery with Transport Layer Security (TLS) prioritized over Secure Web Mail (SWM) and there are multiple recipient domains of which some support TLS and some do not. (Low severity. Reference: KB81420.) Corrects the Secure Socket Layer (SSL) negotiation code to prevent proxies failing with segmentation violations on some SSL negotiation errors. (Low severity. Reference: KB79976.) Corrects the signal sent to SMTP processes for gathering debug information during Minimum Escalation Report (MER) generation with the option 'Run network tests' enabled. The signal previously sent would terminate the processes, which would then be restarted by the health monitor. (Low severity. Reference: KB81562.) Corrects the "From" address on notification emails generated by an encryptiononly appliance, so that email originally received with a BATV (Bounce Address Tag Validation) tagged address will show the original address rather than the BATV tagged one, which would not be recognizable to the recipient. (Low severity. Reference: KB79945.) Corrects a problem when domain relay configuration is pushed to the appliance from a McAfee epo server. It was possible for the DNS server on the appliance to not load the zone files corresponding to the domain relays which caused the emails to these domains to be queued with a 442 'Unable to determine IP address for delivery' error. (Low severity. Reference: KB78084.) Corrects the message-id on email sent via the Secure Web Mail client to conform to RFC2822. (Low severity. Reference: KB81152.) Corrects the handling of Secure Web Mail (SWM) templates so that unsupported '$' escape tokens do not cause delivery failure. (Low severity. Reference: KB79206.) Amends the Secure Web Mail purge to correct an encoding error in file paths, and prevent its selection when another instance of purge is already running, either of which could cause occasional failures. (Low severity. Reference: KB79891.)
Increases the default timeout for uploading to McAfee Quarantine Manager (MQM) to allow for large files. (Low severity. Reference: KB81237.) Corrects a segmentation fault in rmdclean when no database connection is available. (Low severity. Reference: KB81461.) Ensures that ws_retryer process doesn't run when McAfee Quarantine Manager (MQM) is not enabled. (Low severity. Reference: KB81680.) Updates the Secure Web Mail service to prevent the possibility of it going offline entirely when restarted at the same time on both master and failover appliances in a cluster. (Low severity. Reference: KB81577.) Improves the appliance memory management to address various issues caused by running out of memory, including poor performance and resource usage alerts. (Low severity. Reference: KB81543.) Amends the user interface certificate validation so that a valid TLS certificate chain will be verified correctly in cases where the CA certificate in the chain is not among the default CA certificates on the appliance. (Low severity. Reference: KB81860.) Updates the Sender Policy Framework (SPF) library to correctly handle several kinds of erroneous SPF records found in the Domain Name System (DNS). (Low severity. Reference: KB81581, KB81686, KB81774, KB81859.) Disables Transport Layer Security (TLS) certificate caching in the SMTP proxy to prevent certificate errors causing connection failures. (Low severity. Reference: KB81297. Supersedes: 7.5h948770, 7.5h952384, 7.5h960401, 7.5h965187, 7.5h968383.) Content scanning The appliance offers content scanning into the text of certain file types by means of a third party plugin. Update this plugin to address false detections when particular emails were scanned. (Low severity. Reference: KB81155.) Amends the credit card numbers dictionary to prevent false detections on emails with certain spreadsheet attachments. (Low severity. Reference: KB81612.) Updates the anti-spam engine replication to failover and scanning appliances to show the correct status on the user interface, which was always shown as failed. (Low severity. Reference: KB81561.) Removes the constraint on character set mapping so it will work with disclaimer text addition and encoding other than 8bit. This resolves issues with garbled multi-byte characters resulting from clients specifying an incorrect character set encoding, which can now be addressed by character set mapping. (Low severity. Reference: KB81791.) The appliance offers content scanning into the text of certain file types by means of a third party plugin. Update this plugin to resolve issues which caused the SMTP proxy to fail with a segmentation violation when particular attachment files were scanned. (Low severity. Reference: KB81508, KB81676, KB81679, KB81683.) The appliance offers content scanning into the text of certain file types by means of a third party plugin. Update this plugin to resolve issues which caused the SMTP proxy to consume system resources to excess when particular
attachment files were scanned. (Low severity. Reference: KB81157, KB81431, KB81666.) Quarantine Replaces the quarantine digest manager module to address excessive time and resource consumption with large user black and white lists. (Low severity. Reference: KB81681.) Ensures that only one instance of quarantine digest manager runs at any given point in time. (Low severity. Reference: KB81682.) User interface The appliance administrator can create additional user interface accounts with custom roles. Amend the replication process so that such added users can login on the failover device of a blade or cluster system. (Low severity. Reference: KB77886.) Correctly identifies the user who has made a change when prompting others logged on to the user interface to reload configuration. (Low severity. Reference: KB78913.) Amends the spam update network to work with a FTP proxy server which does not proxy FTP over HTTP. (Low severity. Reference: KB79166.) Updates the automatic configuration backup to correctly escape special characters in the FTP password, to prevent failures with some passwords. (Low severity. Reference: KB79454.) Corrects the user interface so that creating a user role with no access privileges does not deny all users access to the Quarantine Configuration pages. (Low severity. Reference: KB79838.) When an IP address is assigned to a cluster appliances, if the number of addresses in the subnet is small, the user interface displays a warning that this will limit the number of scanning devices which can be used. This warning will not now be shown for normal appliances as it is not relevant. (Low severity. Reference: KB81226.) Corrects the httpd configuration to properly block other IP addresses when only specified IP addresses are configured to have access. (Low severity. Reference: KB79990.) Amends the user interface to allow access for users whose role name includes non-ascii characters. (Low severity. Reference: KB80100.) Corrects a fault preventing import of the Commtouch Command Anti Virus engine/database from another McAfee Email Gateway appliance. (Low severity. Reference: KB81242.) Extends the configuration push feature to provide the ability to push component updates to machines of the same version. (Low severity. Reference: KB79953.) Amends the process for inserting statistics into the database so that multiple instances will not run, which could consume all available database connections and prevent the user interface dashboard loading. (Low severity. Reference: KB81537.) The appliance allows a secondary Commtouch Command anti-virus engine to be used for scanning. The user interface component management page is now amended to show the update status correctly when this engine is not used and updates for it disabled. (Low severity. Reference: KB81288.)
Amend the user interface so that generating a Minimum Escalation Report (MER) alone does not enable the "Apply Changes" button. (Low severity. Reference: KB81667.) The user interface gives the ability to view conversation logs for emails appearing in message search. This patch corrects a fault which prevented viewing of the logs for some emails which had been refused after inspecting the data. (Low severity. Reference: KB81631.) Amends the user interface so as not to enable the "Apply Changes" button when forwarding quarantined emails with no configuration change. (Low severity. Reference: KB81516.) Corrects a fault in the configuration push mechanism which prevented Secure Web Mail user and system data from being pushed as it should. (Low severity. Reference: KB81453.) Updates the cron service to address a fault which could cause many instances of the same job to be run on transition to daylight saving time, potentially bringing the system down by exhausting resources. (Low severity. Reference: KB81485.) Makes event 210012 (link state change) available for reports. (Low severity. Reference: KB81635.) Amends network driver counter so that proxy mode throughput is measured correctly, rather than being always zero. (Low severity. Reference: KB81523.) Amends the user interface so that when the TLS domains are spread over multiple pages they can still be re-ordered as required. (Low severity. Reference: KB81843.) Corrects the rejected recipient email count on the dashboard, which was wrongly including emails for recipients not on the permitted recipient list but accepted by LDAP checking. (Low severity. Reference: KB81821. Supersedes: 7.5h965187, 7.5h968383.) Configuration Corrects the epo merge process which corrupted the user black and while list file causing synchronization of the list from McAfee Quarantine Manager (MQM) to fail. (Low severity. Reference: KB81064.) Amends the SMTP proxy so that it logs an error rather than failing to deliver when configured to send audit copies of emails to an address which is not RFC compliant. (Low severity. Reference: KB81678.) Correct an error in the user interface so that users can add email/network groups after clicking on the "Add user group" or "Add network group" link when adding email policies. (Low severity. Reference: KB81229.) Provides for epo distribution of updates, such as anti-virus and anti-spam data, to managed appliances which do not have sufficient network access to retrieve updates themselves in the usual way. (Low severity. Reference: KB81296.) Updates epo configuration conversion to allow editing in epo of protocol presets which point to a network group. (Low severity. Reference: KB79962.) Resolves problems in hotfix 7.5h938406 with editing TLS lists in the user interface. (Low severity. Reference: KB81406, KB81424. Supersedes: 7.5h952384,
7.5h960401, 7.5h965187, 7.5h968383.) Reporting Updates the events system to prevent the unscheduled sending of aggregated events which was sometimes caused by significant configuration changes. (Low severity. Reference: KB78094.) Corrects the parsing of realtime counters which were being shown as always 0 in scheduled reports. (Low severity. Reference: KB77622.) Corrects the recording of CM scan events in the database so that the reason will appear in email reports. (Low severity. Reference: KB77823.) Amends scheduled report generation to show the correct information on quarantine queues when MQM is disabled. (Low severity. Reference: KB78586.) Updates the counting of quarantined items for the dashboard so that the count remains accurate during periods of high traffic. (Low severity. Reference: KB78245.) Updates the SNMP trap to make the object order match that in the MIB. (Low severity. Reference: KB79196.) Amends the health monitor not to generate alerts on restart when a monitored subsystem status changes to available from its initial, unknown, state. (Low severity. Reference: KB81745, KB81822.) Corrects CSV (comma separated values) file export to prevent corruption of multi-line fields. (Low severity. Reference: KB81839.) Updates the SMTP proxy URL reputation detection to prevent cases where the 'Too many URLs found in the message' alert was produced incorrectly. (Low severity. Reference: KB80080.) Amends the aggregated email notification generation to show the correct count of SMTP messages received, rather than always zero. (Low severity. Reference: KB81705.) Corrects the Commtouch Command Anti Virus update so that it does not include any proxy server password in log messages. (Low severity. Reference: KB81684.) Amends the Uninterruptible Power Supply (UPS) monitoring system to ensure that alert emails are sent properly for UPS events. (Low severity. Reference: KB81249.) Corrects timezone offset handling in email reports filtered using Period: Hour to address cases where the Total View tab showed 0 when the Detail and Itemized view tabs showed emails had been processed. (Low severity. Reference: KB81611.) Updates the reporting system to allow correct filtering on user names which include non-ascii characters. (Low severity. Reference: KB79829. Supersedes: 7.5h938406, 7.5h948770, 7.5h952384, 7.5h960401, 7.5h965187, 7.5h968383.) Other issues Corrects an error in Minimum Escalation Report (MER) generation when run from the command line.
