dovecot configuration question userdb driver
by Stanislav 17 Dec '24

17 Dec '24

Greetings, I have a mail server for a few folks, basically my family. My current Dovecot configuration is the following, which works like a charm: ========== passdb { driver = sql args = /usr/local/etc/dovecot/dovecot-sql.conf.ext } userdb { driver = static args = uid=981 gid=981 home=/var/mail/virtual/%d/%n/home } ========== I've decided to deploy Solr to be able to search faster. Now, when I try to execute "doveadm index -A inbox" I get an error "Error: auth-master: userdb list: User listing returned failure" because I'm using the static userdb. My question is, how do I implement the listing users feature while using "static driver" or a similar approach? I really want to keep using the template "/var/mail/virtual/%d/%n/home" instead of defining a custom path for each user. So I came up with this idea to replace "static" with "sql" driver for "userdb" since there's "iterate_query" I can use to achieve my goal, tho I have to define "user_query", so I can do something like: ======= SELECT '/var/mail/virtual/%d/%n/home' AS maildir, 981 AS uid, 981 AS gid FROM mailbox WHERE username='%u' and active='1'; ======= However, this is a useless waste of resources since I'm not really querying anything, and I'm not even sure if there's template support (e.g., %d/%n) in there. Appreciate any help Best

Error: Couldn't open INBOX: Permission denied

I'm trying to get Dovecot working on Rocky 9.5. In 10-mail.conf I have: mail_privileged_group = mail mail_location = mbox:~/mail:INBOX=/var/spool/mail/%u In /var/spool: drwxr-x---. 3 mail mail 64 Dec 13 16:29 mail In /var/spool/mail: -rw-rw----. 1 peter mail 500 Dec 13 16:29 peter When I try to login using Telnet I get the following in /var/log/maillog: Dec 13 17:03:23 Backup dovecot[690594]: pop3-login: Login: user=<peter>, method=PLAIN, rip=172.21.10.5, lip=172.21.10.5, mpid=690664, secured, session=<8Or5zikp7uCsFQoF> Dec 13 17:03:23 Backup dovecot[690594]: pop3(peter)<690664><>: Error: Couldn't open INBOX: Permission denied Dec 13 17:03:23 Backup dovecot[690594]: pop3(peter)<690664><>: Disconnected: Couldn't open INBOX: Permission denied top=0/0, retr=0/0, del=0/0, size=0 (There is a random data between <> - I've deleted it as I'm not sure if it is sensitive. I'm certain I'm typing the password correctly in Telnet and I think the first of the three lines from the log indicate that I successfully connected. But why do I get Permission denied when Dovecot tries to open the INBOX? As far as I can see I've set them right (as per the permissions pasted above).

Rebuild uuidlist?
by Gandalf Corvotempesta 14 Dec '24

14 Dec '24

Guys i did a mess. A bad script made by me, changed (a lot) of filenames in the maildir, in example almost all email filenames were changed. I think I have to rebuild the UID <> filename mapping because dovecot is still trying to read the old file that doesn't exists anymore (it has a new name) Any suggestions? I think this would lead to a full-download of all messages client side, right ?

Mail gone when recreating a folder in a second IMAP session
by Ewald Dieterich 13 Dec '24

13 Dec '24

I'm running Dovecot 2.3.21 with the mdbox mailbox format. I lose mails (with an asterisk, see below) when I'm doing the following in 2 IMAP sessions: Session 1: Create a folder, save a mail and select it: . create folder . append folder {1} . select folder * 1 EXISTS * OK [UIDVALIDITY 1734013510] UIDs valid Session 2: Delete the folder, create it again, save a mail in it, check the number of messages and the uidvalidity:. . delete folder . create folder . append folder {1} . status folder (messages uidvalidity) * STATUS folder (MESSAGES 1 UIDVALIDITY 1734013511) Everything is as expected until here, the uidvalidity was increased by 1, which makes sense. Session 1: Just do a noop . noop * BYE IMAP session state is inconsistent, please relogin. Dovecot notices that something is wrong and closes the connection. This error is logged: Error: Mailbox folder: Corrupted transaction log file /var/spool/dovecot/user/mailboxes/folder/dbox-Mails/dovecot.index.log seq 2: indexid changed: 1734011270 -> 1734011403 (sync_offset=0) Session 2: Check the folder again: . status folder (messages uidvalidity) * STATUS folder (MESSAGES 0 UIDVALIDITY 1734013512) The mail is gone, uidvalidity was again increased by 1, so this is a new folder. I think the problem is that the folder's transaction log is deleted in session 1 in mail_transaction_log_file_open() when Dovecot notices discrepancies in what it expects: if (ret == 0) { /* corrupted */ if (index->readonly) { /* don't delete */ } else { i_unlink_if_exists(file->filepath); } *reason_r = "File is corrupted"; return 0; } This basically recreates the folder, so now it's empty. Here's the asterisk: I know that technically the mail isn't lost because it's still in the storage file and can be recovered. But it's still ugly. And when I copy a mail from another folder instead of appending it, I can't recover it for the folder because the information that the mail was copied is definitely lost. Can this be fixed in Dovecot?

sieve enotify mixes message body and subject
by Cajus Korn 12 Dec '24

12 Dec '24

Dear Community, I found that the following lines of a sieve filter require ["enotify"]; # rule:[enotify] if true { notify :importance "2" :message "New Message received." "mailto:xyz@somedomain.com"; } results in getting the following reply: [...] X-Sieve: Pigeonhole Sieve 0.5.21.1 (49005e73) Message-ID: <dovecot-sieve-1733953974-73072-0(a)ironman.cajus.name> Date: Wed, 11 Dec 2024 22:52:54 +0100 Subject: New Message received.

Shouldn't the message "New Message received." be in the mail body and "Notification of new message." be in the subject? So body and subject got mixed up. Until now I do not know how to debug this further. Any ideas? kind regards Cajus

Sieve not working again
by christian 11 Dec '24

11 Dec '24

Hello, For the past few weeks, I have been facing an issue where user Sieve scripts no longer work. I have configured the filtering of spam emails marked by Rspamd in a before.sieve script, and that works fine. However, the user scripts created via ManageSieve through the Roundcube webmailer do not function anymore. I suspect that this issue started after a Debian 12.6 system upgrade. Could it be that something fundamentally changed, or is Dovecot not fully compatible with Debian 12? However, I find that hard to believe. Despite repeatedly reinstalling the Dovecot environment and verifying file permissions and configurations multiple times, I haven't been able to resolve the issue. I’ve been running Sieve for over 15 years on various servers and have never encountered such problems. Unfortunately, the sieve_user_log = /var/log/dovecot/sieve.log file is not being created. The directory specified in sieve_trace_dir = /var/log/dovecot/sieve is created, but it only logs actions from before.sieve, not from user Sieve scripts. Here are the relevant settings from 90-sieve.conf: plugin { sieve_extensions = +editheader sieve = file:/var/customers/sieve/%u/;active=/var/customers/sieve/%u/.dovecot.sieve sieve_dir = /var/customers/sieve/ sieve_default = /var/customers/sieve/default.sieve sieve_global = /var/customers/sieve/global.sieve sieve_before = /var/customers/sieve/before.sieve sieve_user_log = /var/log/dovecot/sieve.log sieve_trace_dir = /var/log/dovecot/sieve sieve_compile_binary = yes sieve_trace_level = matching sieve_trace_debug = yes sieve_debug = yes } Here’s a log entry from info_log_path = /var/log/dovecot/dovecot-lda.log: Dec 08 12:57:44 lda(info(a)domain.info)<2664475><r1+hOreJVWcbqCgAF7VarQ>: Info: sieve: msgid=<20241208115741.7792d7fe54743ef8(a)fgfunnelsmail.com>: fileinto action: stored mail into mailbox 'INBOX' Here’s a log entry from debug.log: Dec 08 13:12:55 lda(info(a)domain.info)<2680802><SNQDB0eNVWfi5ygAF7VarQ>: Debug: sieve: Using the following location for user's Sieve script: /var/customers/sieve/info(a)domain.info/.dovecot.sieve However, the script is not being applied.

Trying to track down the source of a corrupted cache error
by Grant Keller 10 Dec '24

10 Dec '24

Recently we have been seeing a steady increase (nothing too crazy, just more than usual) in "Deleting corrupted cache record" log errors. What struck me as weird was that it would be for the same message over and over, indicating that the deleted record was making it back into the cache. Digging into one, I realized that the first error was actually this: Dec 4 19:08:59 b.imapd.sonic.net dovecot[2696]: imap(xxx): session=wnZqMH0oHOViI3NN Error: Mailbox INBOX: Maildir filename has wrong W value, renamed the file from /var/spool/mail/17/62/xxx/cur/1733363505.M428026P1491073.b.imapd.sonic.net,S=8966052,W=12155730:2, to /var/spool/mail/17/62/xxx/cur/1733363505.M428026P1491073.b.imapd.sonic.net,S=8966052:2, Dec 4 19:08:59 b.imapd.sonic.net dovecot[2696]: imap(xxx): session=wnZqMH0oHOViI3NN Error: Mailbox INBOX: Deleting corrupted cache record uid=6430670: UID 6430670: Broken virtual size in mailbox INBOX: read(/var/spool/mail/17/62/xxx/cur/1733363505.M428026P1491073.b.imapd.sonic.net,S=8966052,W=12155730:2,): FETCH BODY[]<11796480.393216> got too little data: 359249 vs 359250 Also worth noting that the emails themselves do have a highly unusual number of carriage returns. What causes this and is there a way to fix it besides deleting the offending message?
