So I've just yolo'd the dreaded #dovecot v2.3 => v2.4 upgrade on a Friday afternoon and to my surprise, it was pretty smooth. I have a very simple setup though: only system users, maildir folder in home directory, system authentication via pam. Here's what I did:

1. Pieced together a new minimum viable config from the official docs (10 mins)

2. Checked my old config for settings not accounted for in the new config: …

[1/3]

#IMAP #systemadministration #linux #email #selfhosting

Nice side effect: My config is now down to just a single file with 36 lines, 19 of which are folder name configs probably very specific to my users.

Conclusion: For as long as there's no #openimapd, #dovecot is still the preferred (read simplest) #imap server for little self-hosted setups like mine.

[3/3]
