Re: Expunging and deleting old messages - moving from cyrus-imap

I can't > remember why I have it as I set up Cyrus so long ago. 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>

In case of my dovecot server that bar is missing. Any > idea what should I change on my server to let MUA display that bar? Gmail advertises QUOTA as an CAPABILITY upon connection before login. 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

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?

Namespace configuration
by Scott Q. 31 Oct '24

31 Oct '24

We are having an issue with our namespace configuration, as per the eM Client folks. We present the following namespaces via IMAP, with Dovecot as backend. This is the actual imap conversation 08:37:10.896|03E| 01: A4 ID ("name" "eM Client" "version" "10.1.4393.0" "GUID" "EMCLIENT_V1" "vendor" "eM Client" "contact" "support(a)emclient.com") 08:37:10.961|03E| 01: * ID ("name" "Dovecot") 08:37:10.961|03E| 01: A4 OK ID completed (0.001 + 0.000 secs). 08:37:10.961|03E| 01: A5 NAMESPACE 08:37:11.184|03E| 01: * NAMESPACE (("" ".")("Labels." ".")) (("shared." ".")) NIL 08:37:11.184|03E| 01: A5 OK Namespace completed (0.001 + 0.162 + 0.161 secs). As per them, the problem is the first empty prefix: "The problem is not necessarily in the fact that it is empty but because it is then mixed with another one with a prefix. Logically it means that everything in the empty namespace must be mixed together with the prefixed namespace and that is not really ok." "NAMESPACE (("personal." ".")("Labels." ".")) (("shared." ".")) NIL would make sense as both personal namespaces point to different directory structures." Reading the RFC I'm not understanding this at all, but then again, maybe I'm wrong. Anyone care to shed some light on how multiple namespaces should be defined ? Thank you, Scott

Inboxes incorrectly become /var/mail/%u
by ma.sao＠msa.hinet.net 29 Oct '24

29 Oct '24

With configuration "mail_location = maildir:~/Maildir", incoming mails are always saved to /var/mail/%u , which are invisible to Thunderbird. How do I configure Dovecot to save incoming mails to ~/Maildir/cur/ and ~/Maildir/new/ ? Thank you in advance! context: I replaced my host recently. Version 2.3.13 running in the old host used to correctly save incoming mails to ~/Maildir. I copied the files in /home/user1/Maildir/ Dovecot 2.3.13 managed to my new host where the new Dovecot 2.3.19.1 runs. Thunderbird now correctly displays files in /home/user1/Maildir/cur/ in the new server as inbox mails, but obviously it can not see file /var/mail/user1 in the new server. ===== Output of "dovecot -n" follows. # 2.3.19.1 (9b53102964): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.19 (4eae2f79) # OS: Linux 6.1.0-22-amd64 x86_64 Debian 12.7 # Hostname: example auth_mechanisms = plain login disable_plaintext_auth = no mail_location = maildir:~/Maildir mail_privileged_group = mail namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { driver = pam } protocols = " imap" service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } } service imap-login { inet_listener imap { port = 143 } } ssl = required ssl_cert = </etc/letsencrypt/live/example.com/fullchain.pem ssl_dh = # hidden, use -P to show it ssl_key = # hidden, use -P to show it userdb { driver = passwd } ======== Output of "ls -la /home/user1/Maildir/" in my new host follows. total 112 drwx------ 9 user1 user1 4096 Oct 26 23:39 . drwxr-xr-x 4 user1 user1 4096 Oct 26 23:39 .. drwx------ 5 user1 user1 4096 Oct 26 22:18 .Drafts drwx------ 5 user1 user1 4096 Oct 29 00:11 .Sent drwx------ 5 user1 user1 4096 Oct 26 23:39 .Templates drwx------ 5 user1 user1 4096 Oct 29 00:12 .Trash drwx------ 2 user1 user1 4096 Oct 26 21:14 cur -rw------- 1 user1 user1 609 Oct 26 20:15 dovecot-uidlist -rw------- 1 user1 user1 8 Nov 13 2023 dovecot-uidvalidity -r--r--r-- 1 user1 user1 0 Oct 15 2022 dovecot-uidvalidity.634a88ee -rw------- 1 user1 user1 600 Oct 18 16:39 dovecot.index -rw------- 1 user1 user1 13296 Oct 26 21:23 dovecot.index.cache -rw------- 1 user1 user1 26084 Oct 26 21:14 dovecot.index.log -rw------- 1 user1 user1 744 Oct 22 18:32 dovecot.list.index -rw------- 1 user1 user1 7232 Oct 29 00:12 dovecot.list.index.log -rw------- 1 user1 user1 96 Nov 13 2023 dovecot.mailbox.log drwx------ 2 user1 user1 4096 Oct 26 20:15 new -rw------- 1 user1 user1 33 Nov 13 2023 subscriptions drwx------ 2 user1 user1 4096 Oct 25 21:32 tmp ==== Output of "ls -l /var/mail" follows. total 288 -rw------- 1 user1 mail 35086 Oct 29 18:02 user1 -rw------- 1 daemon mail 36244 Oct 28 12:32 daemon -rw------- 1 debian mail 36223 Oct 26 21:32 debian -rw------- 1 dovecot mail 36248 Oct 28 19:18 dovecot -rw------- 1 games mail 36223 Oct 27 12:38 games -rw------- 1 news mail 36237 Oct 27 13:52 news -rw------- 1 nobody mail 36266 Oct 27 15:31 nobody -rw------- 1 sshd mail 36195 Oct 29 12:36 sshd

Aggregating auth/proxy events
by matus.vlcek＠gmail.com 28 Oct '24

28 Oct '24

Hi, I'm working on aggregating event logs and trying to correlate all related events using session IDs. However, I’m struggling with some events as they're missing the session ID. 1. proxy_session_* events lack a session ID field, making it difficult to pair them with auth_request_* events. 2. when using dovecot as sasl for postfix with a unix listener, both auth_request_* and auth_passdb_request_* events are missing the session ID too. Example of the fields object for auth_request_finished when using smtp. It's missing multiple common fields, but session ID is, imho, the most important one. https://doc.dovecot.org/2.3/admin_manual/list_of_events/#id1 ``` categories: [ "auth", "service:auth" ] "fields": { "translated_user": "alex", "mechanism": "LOGIN", "real_remote_ip": "X.X.X.X", "user": "alex", "transport": "insecure", "local_ip": "X.X.X.X", "remote_ip": "X.X.X.X", "real_local_ip": "X.X.X.X", "policy_result": "ok", "service": "smtp", "duration": 96764, "original_user": "alex" }, ``` Would it be possible to add session ID fields to these logs? Alternatively, is there another method to correlate all the session related logs? Thanks, Matus Dovecot v. 2.3.21
