💖 postlogd — the Postfix internal log server, bestie edition 💖

okay so this is POSTLOGD(8postfix) — the Postfix internal log server, and honestly? she's the quiet backstage icon who makes everything else look good. let's get into it 🎀

✨ NAME ✨

postlogd — Postfix internal log server. yes that's the whole name. short. mysterious. main character energy 👑

🌸 SYNOPSIS 🌸

postlogd [generic Postfix daemon options]

that's it. no drama, no extra flags, just vibes and generic Postfix daemon options 🦋

💜 DESCRIPTION 💜

so basically this program logs events on behalf of Postfix programs when the maillog configuration parameter specifies a non-empty value. that's the whole job. she's the designated note-taker of the friend group and she takes her job VERY seriously ✨

😭 BUGS 😭

ngl bestie, there's some messy stuff here and we're gonna be honest about it:

  • Non-daemon Postfix programs don't know that they should log to the internal logging service before they have processed command-line options and main.cf parameters. so those programs still log earlier events to the syslog service. they just... find out too late. relatable honestly 💀
  • If Postfix is down, the non-daemon programs postfix(1), postsuper(1), postmulti(1), and postlog(1), will log directly to $maillog_file. These programs expect to run with root privileges, for example during Postfix start-up, reload, or shutdown. 👑
  • Other non-daemon Postfix programs will never write directly to $maillog_file (also, logging to stdout would interfere with the operation of some of these programs). These programs can log to postlogd(8) if they are run by the super-user, or if their executable file has set-gid permission.
🚨 DO NOT set this permission on programs other than postdrop(1), postqueue(1) and (Postfix >= 3.7) postlog(1). like, for real for real. not it. 🙈

🎀 CONFIGURATION PARAMETERS 🎀

Changes to main.cf are picked up automatically, as postlogd(8) processes run for only a limited amount of time. Use the command "postfix reload" to speed up a change. slay, instant glow-up ✨

The text below provides only a parameter summary. See postconf(5) for more details including examples.

  • config_directory (see 'postconf -d' output) — The default location of the Postfix main.cf and master.cf configuration files. 🗂️
  • maillog_file (empty) — The name of an optional logfile that is written by the Postfix postlogd(8) service. this is literally her whole thing 💖
  • process_id (read-only) — The process ID of a Postfix command or daemon process. no touching, she's read-only 🫶
  • process_name (read-only) — The process name of a Postfix command or daemon process. also read-only, hands off bestie 🙈
  • syslog_name (see 'postconf -d' output) — A prefix that is prepended to the process name in syslog records, so that, for example, "smtpd" becomes "prefix/smtpd". it's giving ✨nameplate✨
  • service_name (read-only) — The master.cf service name of a Postfix daemon process. read-only, obviously 💅
  • postlogd_watchdog_timeout (10s) — How much time a postlogd(8) process may take to process a request before it is terminated by a built-in watchdog timer. 10 seconds and then the watchdog says okay bye 😭
