SecurityGateway 9.0.0 - January 10, 2023

SPECIAL CONSIDERATIONS

• [25882] By default, mailbox names that contain a plus character (+) will now be considered to be subaddressed. The user verification process will consider the subaddress to be an alias. For example, user+folder@example.com will resolve as user@example.com and an alias where user+folder@example.com = user@example.com. New users for which the mailbox name contains a plus character cannot be created. Existing users for which the mailbox name contains a plus character are not automatically removed. They can be fixed up (renamed or merged) by running the Setup | Accounts | User Verification Sources | Verify Users process. An option to restore the previous behavior "Allow user mailbox name to contain plus (+) character" has been added to Setup | Accounts | User Options. When enabled, these mailbox names will not be considered aliases/sub-addresses. For example, user+folder@example.com will be considered its own user and not an alias of user@example.com.

MAJOR NEW FEATURES

• From Header Screening
  • [24420] New options have been added (Security | Anti-Spoofing | From Header Screening) to help expose fraudulent (spoofed) from headers sent from spammers that could potentially trick users into believing a message was submitted from a legitimate source.
• Web Interface Usability Enhancements
  • [13473] Added the ability to include up to four additional search header patterns, results, and reasons on message pages. Header patterns can be separated by AND/OR using a button toggle. Results and Reasons are always separated by OR

When a browser that supports HSTS receives an HSTS header and the SSL certificate is valid, and any future HTTP requests made to the same domain will be automatically upgraded to HTTPS.
• [25874] SecurityGateway now supports TLS 1.3 on newer versions of Windows. Windows Server 2022 and Windows 11 have TLS 1.3 enabled by default. Windows 10 versions 2004 (OS Build 19041) and newer have experimental TLS 1.3 support that can be enabled for inbound connections by setting the following in the registry:

              HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.3\Server
                  DisabledByDefault (DWORD) = 0
                  Enabled (DWORD) = 1

• [26075][23613] Extracting plain text from attachments now occurs in a separate process (filterhost.exe). This prevents a hung iFilter .dll from impacting the SecurityGateway process.
• [26348] Added "Referrer-Policy" and "Content-Security-Policy" HTTP headers
• [26325] Updated ClamAV to version 0.105.1

• [26281] Made the Change Password page have the Change Password button disabled until the passwords are valid.
• [26324] Added an option "Only delete messages from active archive stores" to Setup | Archiving | Compliance that controls if the "Automatically delete archived messages older than X days(s)" option only applies to active archive stores.  This option is enabled by default.  When enabled, the behavior is unchanged from previous versions.
• [26252] SMTP socket connection is now disconnected for SIEVE actions "error" or "reject" if they occur during the IP phase.
• [26251] At startup, locked messages in the inbound queue are now moved to the CrashDumps\InboundQueue directory. Messages in the inbound queue are unlocked when a response is sent to the sender. Locked messages may be orphaned in the inbound queue if the SecurityGateway process crashes or is terminated before it has a chance to shut down. Since the sender did not receive a response to the SMTP DATA command, they should send the message again. Delivering the message may result in the recipient receiving multiple copies. However, the content of these messages may be helpful for debugging crashes.  Any messages moved to this directory are automatically deleted after 30 days.
• [25712] LetsEncrypt - Changed the Log function to use add-content instead of out-file. Add-content uses the default system code page which should enable the log file to be viewed in SecurityGateway. No change will be made to the encoding of the log file until a new log file is created.
• [25713] LetsEncrypt - Updated the script to work with PS 7.
