Expand systemd-tmpfile.conf from 4 to 50 lines (+1,150%) as part of zmfixperms replacement. Provides declarative directory management for all MTA-related services. Changes: - Add postfix master and main configuration files - Add postfix bysender database files - Add postfix RE files (tag_as_foreign, tag_as_originating) - Add virtual domain configuration files with postfix group access - Add postfix setgid binaries (postqueue, postdrop) with mode 2755 - Add postfix data directory structure - Add postfix spool directories with special permissions: * public: 0710 (postfix:postdrop) * maildrop: 0730 (postfix:postdrop) - Add amavisd directories (anti-spam/anti-virus) - Add spamassassin data directories - Add altermime directory (MIME message modifier) - Add cbpolicyd directories (postfix policy daemon) Post-install requirements documented in comments: - Recursive permission removal on data directory (chmod -R go-w) - Recursive ownership change on spool directory (chown -fR) - Additional spool subdirectories created at runtime by postfix SELinux support: - Automatic context restoration via 'z' directives (lines 2-24) - No manual chcon/restorecon needed Addresses CO-2524 (IN-754): Replace zmfixperms with tmpfiles.d

Session 10 Update: Critical PKGBUILD FixCommit During comprehensive PKGBUILD review, discovered a critical issue:
Changed from: Status: Build-blocking issue resolved ✅ |
Change from: systemd-tmpfiles --create To: systemd-tmpfiles --create /usr/lib/tmpfiles.d/carbonio-mta.conf Benefits: - Only processes this package's tmpfiles.d configuration - Avoids redundant processing of other packages' configs - Faster execution during package installation - Clear separation of concerns between packages This prevents each package from reprocessing all tmpfiles.d configs in /usr/lib/tmpfiles.d/ during postinst, which was inefficient when packages have dependency relationships.

Remove ClamAV data directory management from carbonio-mta tmpfiles.d configuration as it's now handled by carbonio-clamav package directly. Changes: - Remove /opt/zextras/data/clamav/db entry from systemd-tmpfile.conf - Update PKGBUILD checksum for systemd-tmpfile.conf This follows the principle that packages should manage their own directories. The carbonio-clamav package now includes its own tmpfiles.d configuration for its data directory. Related to CO-2524 (IN-754) - tmpfiles.d migration
Remove amavisd, spamassassin, and cbpolicyd directory management from carbonio-mta as these are now handled by their respective third-party packages. Changes: - Removed 4 amavisd/spamassassin entries (lines 39-43) - Removed 2 cbpolicyd entries (lines 51-53) - Reduced from 58 to 48 lines - Updated PKGBUILD checksum Directories moved to: - carbonio-amavisd: /opt/zextras/data/amavisd/* - carbonio-perl-mail-spamassassin: /opt/zextras/data/spamassassin, /var/spamassassin - carbonio-policyd: /opt/zextras/data/cbpolicyd/* Kept in carbonio-mta: - /opt/zextras/data/opendkim (carbonio-opendkim doesn't create it) - /opt/zextras/data/altermime (carbonio-altermime doesn't create it) Related to CO-2524 (IN-754) - tmpfiles.d migration
Removes postfix directory management from carbonio-mta - these are now handled by carbonio-postfix package via its own tmpfiles.d and sysusers.d. Changes: - Removed postfix directory definitions (lines 27-37, -11 lines) - Removed postfix-related notes (lines 45-48, -4 lines) - Kept MTA-owned config file permissions (master.cf.in, bysender, RE files, virtual domain configs) - Updated checksum Package boundaries: - carbonio-postfix: Manages postfix users, groups, base directories, SGID binaries - carbonio-mta: Manages MTA-specific config files that need group postfix access Code reduction: - Before: 49 lines → After: 33 lines (-16 lines, -33%) Related: CO-2524, IN-754
The group definition had incorrect syntax with too many fields: g carbonio-mta - - - "carbonio mta group" This caused systemd-sysusers to fail with error: 'carbonio mta group' is not a valid login shell field The correct sysusers.d group format is: g NAME ID Fixed by removing extra fields and adding comments for clarity. Fixes: - carbonio-mta user/group creation failure - carbonio-core post-install failure (exit code 73) - systemd-sysusers processing errors Impact: Critical - blocks proper package installation
Directory creation for amavisd, clamav, opendkim, postfix is now handled by their respective packages' tmpfiles.d configurations: - carbonio-amavisd: /opt/zextras/data/amavisd/* - carbonio-clamav: /opt/zextras/data/clamav/db - carbonio-postfix: /opt/zextras/data/postfix/* - carbonio-mta: /opt/zextras/data/opendkim, altermime This removes ~100 lines of duplicate directory setup code from all 4 postinst functions.
