POSTFIX-ADD-FILTER(8)

💖 POSTFIX-ADD-FILTER 💖

okay bestie, welcome to postfix-add-filter, section 8 of the System Manager's Manual — yes, the big-girl admin section, we love that for us 🫶

---

✨ NAME ✨

postfix-add-filter — literally just adds a filter service to your Postfix master.cf. that's it. that's the whole job. 💅

---

🌸 SYNOPSIS 🌸

postfix-add-filter [smtp service name...] [smtpd port...]

like, you hand it some names and some ports and it goes to work. no cap.

---

🦋 DESCRIPTION 🦋

so the postfix-add-filter(8) command adds an smtp service named smtp service name and an smtpd server listening on smtpd port into /etc/postfix/master.cf — and the whole point is to make integrating SMTP filters like amavisd-new or clamsmtp actually, you know, work. ✨

the configuration it writes is based on the upstream recommendations for amavisd-new 2.6.0. but heads up bestie 👑: administrators should verify it is appropriate for their requirements. it's giving "template, not gospel."

the original file gets copied before modification and left in /etc/postfix so you can revert your changes easily. safety net? iconic. we stan a rollback. 🎀

also available in the Debian package for Postfix version 2.5.3 and later. iykyk.

---

💀 DIAGNOSTICS 💀

if the smtp service name you gave or the smtpd port you gave already appears in the master.cf? a message gets printed to standard out and master.cf will not be modified. nothing happens. it just says so and vibes. 🫶

---

🌈 ENVIRONMENT 🌈

• MAIL_CONFIG — directory with Postfix configuration files. 📁

not me telling you this: the postfix-add-filter(8) command should use this, but it currently doesn't. it is hard coded to /etc/postfix. this should be changed. 😭

fr fr. it's a known situation. we move.
