Package: postfix Version: 3.7.10-0+deb12u1 Severity: normal Tags: upstream X-Debbugs-Cc: debbug.post...@sideload.33mail.com
When an smtp command failed to send an outbound message, Postfix neglected to correctly log the syslog_name as specified by this option: -o syslog_name=postfix/smtptor The logs are shown in bug report 1069949¹. This severely crippled troubleshooting efforts because it misleads testers about what actually executed. Notice in the logs of that bug report that a well-behaved smtp program correctly yielded the “postfix/smtptor” string. In the failure scenario, the string “postfix/smtp” was logged, falsely implying that the wrapper script was never called, yet it actually logged output from the wrapper script. This resulting deception led the bug chase down the wrong path. I suspect whatever code applies the custom syslog_name is running sequentially late and an initialised default value of “postfix/smtp” is used as a placeholder. A low-effort fix would be to change that initialisation to something that’s at least non-misleading, such as: * “postfix/TBD” * “postfix/smtpAppTBD” * “postfix/UNKNOWN” * “postfix/UNSET” * “postfix/UNSETsmtp” * “postfix/DEADBEEF” * “postfix/ifYouSeeThis,TellWietse” * “postfix/thisWillNeverHappen” * “postfix/youFoundAbug” Any of those as an initialisation default would at least avoid misinformation. Going the extra mile would be fixing whatever caused the logger to act before the custom syslog_name took effect. ¹ https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1069949 -- System Information: Debian Release: 12.5 APT prefers stable-updates APT policy: (990, 'stable-updates'), (990, 'stable-security'), (990, 'stable'), (500, 'oldstable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 5.10.0-28-amd64 (SMP w/2 CPU threads) Kernel taint flags: TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages postfix depends on: ii adduser 3.134 ii cpio 2.13+dfsg-7.1 ii debconf [debconf-2.0] 1.5.82 ii dpkg 1.21.22 ii e2fsprogs 1.47.0-2 ii init-system-helpers 1.65.2 ii libc6 2.36-9+deb12u6 ii libdb5.3 5.3.28+dfsg2-1 ii libicu72 72.1-3 ii libnsl2 1.3.0-2 ii libsasl2-2 2.1.28+dfsg-10 ii libssl3 3.0.11-1~deb12u2 ii netbase 6.4 ii ssl-cert 1.1.2 Versions of packages postfix recommends: ii ca-certificates 20230311 ii python3 3.11.2-1+b1 Versions of packages postfix suggests: ii emacs-gtk [mail-reader] 1:28.2+1-15 ii libsasl2-modules 2.1.28+dfsg-10 ii mailutils [mail-reader] 1:3.15-4 ii neomutt [mail-reader] 20220429+dfsg1-4.1 pn postfix-cdb <none> ii postfix-doc 3.7.10-0+deb12u1 pn postfix-ldap <none> pn postfix-lmdb <none> pn postfix-mta-sts-resolver <none> pn postfix-mysql <none> ii postfix-pcre 3.7.10-0+deb12u1 pn postfix-pgsql <none> pn postfix-sqlite <none> ii procmail 3.22-27 ii systemd-resolved [resolvconf] 252.22-1~deb12u1 ii ufw 0.36.2-1 -- Configuration Files: /etc/postfix/post-install changed [not included] /etc/postfix/postfix-files changed [not included] /etc/postfix/postfix-script [Errno 2] No such file or directory: '/etc/postfix/postfix-script' -- debconf information excluded
