CHK_CYRUS(8)

💖 CHK_CYRUS 💖

okay bestie, welcome to chk_cyrus — section 8 of the Cyrus IMAP manual, and literally your new fave consistency-checking icon 🎀

---

✨ NAME ✨

chk_cyrus — Cyrus IMAP documentation

does a consistency check of the Cyrus IMAP mail spool. yep that's the whole vibe 💅

---

🌸 SYNOPSIS 🌸

chk_cyrus [ -C config-file ] [ -P partition | -M mailbox ]

---

🦋 DESCRIPTION 🦋

so chk_cyrus is the one that runs a consistency check on the cyrus datastore, and it spits out a whole list of files/directories that should exist but literally don't 😭 it's giving "where did they go" energy.

heads up tho, the tea is split:

• status messages go to stderr
• the list of files/directories goes to stdout

and that list?? you can hand it straight to a backup program to help with a partial restoration, for instance. so useful, no cap 🫶

also chk_cyrus reads its configuration options out of the imapd.conf(5) file, unless you say otherwise with -C. periodt.

---

💅 OPTIONS 💅

• -C config-file — use the specified configuration file config-file instead of the default imapd.conf(5). iconic behaviour tbh ✨
• -P partition, --partition=partition — limit to partition partition. may not be specified with -M. pick a lane bestie 🙈
• -M mailbox, --mailbox=mailbox — only check mailbox mailbox. may not be specified with -P. again. one or the other. 💀

IMPORTANT: the mailbox has to be specified in the internal format. so instead of writing user/john/Trash@example.org, you're gonna want to write example.org!user.john.Trash. yes fr fr, that's the format. don't fight it 🌈

---

🎀 EXAMPLES 🎀

chk_cyrus -P default

perform consistency checks on default partition. slay ✨

chk_cyrus -C /usr/local/etc/imapd-slot1.conf -P default

perform consistency checks on default partition using the specified configuration file. look at you customising 👑

chk_cyrus -M user.marysmith

perform consistency checks on mailbox user.marysmith. go marysmith go 🦋
