SecurityGateway 11.0.4 - 2025-12-02
CHANGES AND NEW FEATURES
- [28966] Updated embedded database engine to Firebird 5.0.3
FIXES
- [28827] fix to SMTP server does not reject MAIL FROM commands with no address specified (e.g., "MAIL FROM:" with nothing after the colon). The server now returns "513 Invalid address" for empty MAIL FROM commands while continuing to accept the valid null sender syntax "MAIL FROM:<>".
- [27896] fix to quarantine action confirmation prompts can be bypassed by automated email scanners and security tools that follow links in quarantine notification emails. The "Never ask me again" preference is now stored as a browser-specific cookie instead of a server-side database setting, preventing automated systems from triggering unintended quarantine actions.
- [29021] fix to unable to archive messages that are DKIM/ARC signed locally due to file size does not match.
- [29016] fix to system-generated messages (DMARC reports, bounce notifications, etc.) are not DKIM signed when global DKIM signing is enabled and the sending domain is configured to use global settings.
