If by expire, you mean expunge, this is more or less what I used in a nightly cron script doveadm expunge -A $ mailbox 'Deleted Items' OR mailbox 'Deleted Messages*' OR mailbox Junk OR mailbox Trash OR \( mailbox INBOX Deleted $ \) BEFORE 7d In English, for all users, delete any messages in commonly named trash folders or any messages in INBOX marked as deleted that are older than a week. I recall one quirk: if the mailbox didn't have a cached entry for the message's age, the filter criteria would miss this and it would remain in the mailbox. I'm not sure if this still happens, but I got around this by seeding the cache by doing a doveadm search for that metadata (date.received?). Joseph Tam <jtam.home(a)gmail.com>

Dovecot advertises QUOTA as an CAPABILITY only after login. GPT believes this is why Tbird doesn't show the quota on the status bar, because it's looking for the quota before login and not after. Does anyone know if its possible to get dovecot to advertise QUOTA before login?

IMAP quota reporting free disk space
by piotr＠connecta.pl 06 Nov '24

Hi, Is it possible to make IMAP quota commands report free filesystem space? I don't want to set quota limits to individual users, but it would be nice to have an information on the bottom of Thunderbird window about free disk space (it could be percentage of the total disk size). Anyway I have trouble with quota reporting itself, because I tried to setup a regular quota (100G) first, but somehow Thunderbird doesn't report free quota as it does in case of Gmail accounts. I added to 20-imap.conf: protocol imap { mail_plugins = $mail_plugins quota imap_quota } and to 90-quota.conf: plugin { quota = maildir quota_rule = *:storage=100G } What else should I add to enable reporting? (without warning emails, commands changing quota and all that stuff) P.

Upgrade Dovecot Cluster 2.2 to 2.3
by Steven Varco 05 Nov '24

05 Nov '24

Hi All I’m planing to upgrade/migrate my dovecot cluster with two dovecot 2.2.36 nodes to 2.3.16. They use Maildir als IMAP backend and will continue to use that in the future. Can I just: - Install a new Server (AlmaLinux 9) - Stop dovecot on the old node-2 - Copy all the data from the old mail directory of node-2 to the new one - Install dovecot 2.3 on the new on with more or less the same config and let it run - Repeat the same with old node-1 ? Or would it be better to start of with an empty mail directory and let the other old node imapsync the data to the new one? - What would the advantage be (over the disadvantage that it may take some time to get everything synced)? I know that Maildir are just static files, so moving them to the new server should not be a problem. I’m thinking more about indexes created by dovecot 2.2.36… Are they read without issues with the newever dovecot 2.3.16 or should I consider a re-index. or something the like? thanks in advance, Steven -- https://steven.varco.ch/ https://www.tech-island.com/

IRC channel link on the website
by Sebastian Crane 04 Nov '24

04 Nov '24

Dear all, On the Dovecot website, I noticed that the IRC link isn't clickable: https://www.dovecot.org/support/ The Markdown-esque square brackets suggest to me that this should be a hyperlink, but it's just plain text at the moment. The other issue is that there is no hash symbol before the channel name, so even if it were clickable the user's IRC client would start a private message rather than join the channel. Best wishes, Sebastian

dovecot-lda from www-data - doesnt work
by Sebastian Nielsen 01 Nov '24

01 Nov '24

m trying to deliver email from a webform, but its not working. I then tried manually in the console: WORKS: sudo -u info /usr/lib/dovecot/dovecot-lda -d info DOES NOT WORK: sudo -u www-data /usr/lib/dovecot/dovecot-lda -d info sudo -u postfix /usr/lib/dovecot/dovecot-lda -d info sudo -u dovecot /usr/lib/dovecot/dovecot-lda -d info I need to be able to deliver email from "www-data" to any user on the system (that is a valid dovecot-lda mail user). It seems a security setting blocks it. I have already set authdb to 0777 in dovecot settings (because otherwise it gives an error about lookup rights), and also enabled stats-writer and stats-reader with 0666. so no more error messages in log, but the above commands that does NOT work, terminate immediately, while the working command waits for email from STDIN. No error messages in either log or on STDOUT/STDERR. What can be the problem?
