nullmailer-smtpd(8)

✨ nullmailer-smtpd ✨

okay bestie, welcome to the manual page for nullmailer-smtpd, from the System Manager's Manual section 8 — yes it's a real one, and yes it's lowkey iconic 💅

🎀 NAME 🎀

nullmailer-smtpd — the sendmail emulator interface for nullmailer 🦋

🌸 SYNOPSIS 🌸

nullmailer-smtpd

that's it. no flags. no arguments. she just is ✨

💖 DESCRIPTION 💖

okay so picture this: this program is a front end program for nullmailer-queue. it's not out here doing the heavy lifting itself, no no — it's the vibe liaison 🫶

the way it works is, nullmailer-inject invokes it when mail senders request a sendmail -bs SMTP interface for sending email. so basically when some program out there is like "hey can i speak sendmail to you", this is who picks up the phone 📞

and then — and this is the main character part — this program accepts SMTP protocol on standard input. so it's sitting there, reading SMTP off stdin, being all polite and protocol-correct 😌

on successful completion as far as the DATA command, this program executes nullmailer-queue directly with the appropriate sender and recipients. like, hand-off, no middleman, straight to the queue bestie 🏃‍♀️💨

if you want the details on how messages are actually queued, go read the documentation for nullmailer-queue. that's its whole job, not hers ✨

🌈 RETURN VALUE 🌈

always exits 0. no cap. always. 🤯

so where do the errors go? not the exit code, that's for sure. any errors are notified to the caller by SMTP extended error codes — so it tells you what went wrong in SMTP-speak, which honestly? very on brand 💅
