POP3D(8)

💖 POP3D 💖

okay bestie, so this is pop3d and pop3d-ssl — the little duo that starts and stops your Courier POP3 server ✨ they live in section 8 of the manual (that's the sysadmin/vibes section, iykyk) and honestly? they're not complicated, they're just iconic 💅

---

🌸 SYNOPSIS 🌸

/usr/sbin/pop3d [[start] | [stop]]

/usr/sbin/pop3d-ssl [[start] | [stop]]

that's it. that's the whole vibe. start, stop, or nothing at all 🎀

---

✨ DESCRIPTION ✨

so when you run pop3d start, it goes and reads the POP3 server configuration from /etc/courier/pop3d (and also /etc/courier/pop3d-ssl), then it runs couriertcpd(8) to accept all the new POP3 connections coming in 🫶

and when you run pop3d-ssl start, it reads /etc/courier/pop3d-ssl (and also /etc/courier/pop3d) and runs couriertcpd(8) to accept new POP3-over-SSL connections. secure queen behavior honestly 🔥

Note: the Courier POP3 server supports Maildir mailboxes only. that's the whole list. no mbox, no nothing. it's Maildir or it's nothing, periodt 💀

then pop3d stop and pop3d-ssl stop — those shut down their respective servers. like turning off the lights when you leave 🕯️
