BUG REPORT: MAIL-CRYPT plugin: doveadm mailbox cryptokey -O option
by ean365 17 Aug '21

17 Aug '21

Aki: I have identified a bug in the "*-O*" option of "*doveadm mailbox cryptokey password*" plugin command -- it is expecting an argument, but it is supposed to be a boolean option. I have also identified the (simple) fix to the source on github... /I am a dovecot community noob, so please forgive me if this has already been identified... (if so, I hope it gets fixed soon)... / The "-O" option in *struct doveadm_cmd_mcp_key_password* is set to expect a *STR* parameter, but it should be *BOOL*. See line 1027 in plugins/mail-crypt/doveadm-mail-crypt.c of master branch... Currently: ***DOVEADM_CMD_PARAM**(**'O'**, **"ask-old-password"**, CMD_PARAM_STR, **0**) *Should be: ***DOVEADM_CMD_PARAM**(**'O'**, **"ask-old-password"**, CMD_PARAM_BOOL, **0**)* Workaround is to specify *-O* last on command line with a dummy argument, like this: *doveadm mailbox cryptokey password -N -O ""* Also, a quick question and suggestion -- Why does the *doveadm mailbox cryptokey password* command not ask for a new password twice, with a check that both entries must match before the password is changed? The last thing we would want is to type something wrong accidentally, and change the new password to something unknown -- rendering encrypted email unrecoverable. I would like to suggest that the code in *cmd_mcp_key_password_run* be amended to include verifying password entry twice. (I am writing a simple addition to postfixadmin that changes the user's mail-crypt password whenever they use postfixadmin to change their login password. It calls *doveadm* to change the keys. I came across this bug while working through this.) Thanks for all your help! Eric **

Mailbox problem on centos O/S after some "fiddling"
by John Richards 28 May '21

28 May '21

Good day from Somerset, England Version 2.2.10 Problem after a huge centos update Data:- Server has 8 mailboxes under /var/mail/"user name" history:- After update, mail to ONE user was going into mqueue as undeliverable Had to delete and recreate the user. somewhere along the line (ME!) /var/mail/;imap var/mail/new were deleted After new user and reboot server no one could access mailboxes with password error except ONE user randomly....This created the /var/mail/.mbox folder and sub folders but with the owner as the user name. Then any mail for other users was put in the /var/new folder and just sat there. only the "owner" of this folder could get mail, everyone else was prohibited with password error. chown the folder (owner:group) to root did nothing BUT When .mbox was give PUBLIC execute permissions (771) suddenly everything works fine! I do not understand why dovecot creates this folder as we ONLY ever use pop3 (currently with plain text auth but going to secure when this sorted) for mail and also why when it writes the blank folder it "owns" it with the user accessing it (also the /var/mail/new folder takes the same owner) I have trolled everywhere and spent a whole day on this so any clues would be very gratefully accepted as do not like to leave this folder as 771 (note the folder INBOX within it is only 770 and the log file in that is 660) Is this INBOX needed at all for pop3 ? rgds John Richards UK ================= dovecot -n # 2.2.10: /etc/dovecot/dovecot.conf # OS: Linux 3.10.0-514.2.2.el7.x86_64 x86_64 CentOS Linux release 7.3.1611 (Core ) ext4 auth_mechanisms = plain login disable_plaintext_auth = no mail_location = mbox:/var/mail/:INBOX=/var/mail/%u mbox_write_locks = fcntl 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 = shadow } protocols = pop3 service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } } ssl_cert = </etc/pki/tls/certs/watchetwebdesign.co.uk.crt ssl_key = </etc/pki/tls/private/watchetwebdesign.co.uk.key userdb { driver = passwd }

Hi, I'm running every week in cron "doveadm expunge -A mailbox Spam before 30d" and monthly "doveadm quota recalc -A". After the upgrade to dovecot 2.2.12 (from 2.1.17), "doveadm -A" sometimes exit with this error: doveadm(user(a)domain.com): Error: User listing returned failure doveadm: Error: Failed to iterate through some users # echo $? 75 If I re-run the same command the user where doveadm stops changeing (always in alphabetical order): info@ mario@ pippo@ zazza@ and finally, after 3 or 4 run, ends with success. I have enable debug (via doveadm -D and auth/mail debub in 10-logging.con) but there are no errors or difference in the log when doveadm exit with the error (error code is 75).

IMAP session hangs on 8k-long commands if COMPRESS=DEFLATE is enabled
by Guilhem Moulin 21 Apr '21

21 Apr '21

Hi there, Dovecot 2.3.7 appears to hang when the client sends a long command after enabling the IMAP COMPRESS extension [RFC 4978]. PoC script attached along with the doveconf(1) output. Without COMPRESS=DEFLATE, and with the default ‘imap_max_line_length’ value (64k) I'm able send commands up to 65539 bytes long (that's 3 bytes more than 2¹⁶, so maybe the leading tag and the trailing CRLF aren't counted), after which Dovecot rightfully replies with tagged BAD responses. $ COMPRESS=n /tmp/many-fetch.pl 65539 […] C: x UID FETCH 1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,… [65539 bytes] S: x OK Fetch completed (0.005 + 0.001 + 0.004 secs). C: x UID FETCH 1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,… [65540 bytes] S: x BAD Error in IMAP command UID FETCH: IMAP command line too large (0.001 + 0.001 secs).

With COMPRESS=DEFLATE however, the server never sends anything back when the command size exceeds 8192 bytes: $ COMPRESS=y /tmp/many-fetch.pl 8192 […] S: x OK [READ-ONLY] Examine completed (0.001 + 0.000 secs). C: x UID FETCH 1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,… [8191 bytes] S: x OK Fetch completed (0.001 + 0.000 secs). C: x UID FETCH 1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,… [8192 bytes] S: x OK Fetch completed (0.001 + 0.000 secs). C: x UID FETCH 1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,… [8193 bytes] [ _hangs until the server terminates the session for inactivity_ ] S: * BYE Disconnected for inactivity. strace(1) show that Dovecot didn't send the response, even though the server log indicates that it's able to fully read the command. Interestingly, when setting ‘imap_max_line_length’ to 4096, the server also hangs after receiving a command of size >4096 bytes (instead of replying with a tagged BAD response). $ COMPRESS=y /tmp/many-fetch.pl 4096 C: x UID FETCH 1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,… [4095 bytes] S: x OK Fetch completed (0.001 + 0.000 secs). C: x UID FETCH 1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,… [4096 bytes] S: x OK Fetch completed (0.001 + 0.000 secs). C: x UID FETCH 1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,… [4097 bytes] [ _hangs until the server terminates the session for inactivity_ ] I'm also able to reproduce the buggy behavior against Dovecot versions found in other Debian releases. It's identical with 2.3.4 (Buster), the server also hang past 8192 bytes. 2.2.27 (Stretch) and 2.2.13 (Jessie) are able to send replies to 8k-long commands, but hang past 65536 bytes. For all 3 releases, without COMPRESS=DEFLATE Dovecot doesn't hang and rightfully sends tagged BAD responses to commands of size >65539 bytes. So while the hanging behavior appears to be a long-standing bug, the fact that's it's now hit at min($imap_max_line_length, 8192) instead of $imap_max_line_length seems to be a regression from somewhere between 2.2.27 and 2.3.4. Cheers, -- Guilhem.

Hi, Here is the problem that occured: #sudo doveadm -D altmove -u vv(a)vito.pp.ua all works properly and moves all storage to alt dir.

migration with doveadm backup to new cluster running dovecot 2.2.36 and replicator
by Thomas Winterstein 12 Jan '21

12 Jan '21

Hello everyone, we are working on migrating from dovecot 2.0.9 (maildir) to 2.2.36 (mdbox). The new cluster has two backend mail servers which replicate through doveadm replicator. To move the data initially we use doveadm backup (imapc). Our migration command doveadm -o mail_fsync=never backup -R -u $user imapc: To test the replication of new and purge of old mails with live data changes we ran imapc on a daily basis but encountered the problem that some mailboxes multiplied in size. We then made sure that imapc and replication don't run at the same time but after the first incremental imapc process, we still had the same problems. The doveadm-backup man-page states that it's possible to run it multiple times during migration. But is it also possible to have the replicator running in between? From our understanding the doveadm backup should just work as an imap connection between the servers, synchronizing all changes made on the source to the destination. Or does the conversion from maildir to mdbox format in our case produce the problems? If you're not supposed to run the replicator before having fully migrated, how can we shorten the downtime? rsync? And how can we be sure that similar problems don't occur after the migration if we can't test all mechanisms together with live data? thanks -- Thomas Winterstein

LDA ignores virtual mailbox settings
by Toni Mueller 01 Jan '21

01 Jan '21

Hi, I have a Debian/Buster system with Postfix and Dovecot from the Debian repo, and with virtual users only (ie, no system users). These virtual users are having all of their uids, gids, homes and mail quota in an PostgreSQL database. The intent is to have postfix deliver the email via dovecot's LDA, so I can set quota on a per-user basis. But for some odd reason, Dovecot's LDA can't find the user data from the userdb, and then complains about not being able to write to /var/mail. The following example shows how things fail when delivering a message from Postfix's queue (therefore, the passdb failure is expected): In /etc/dovecot.conf, I have this, amongst other things: mail_location = maildir:~/Maildir:INBOX=~/Maildir passdb { driver = sql args = /etc/dovecot/dovecot-sql.conf.ext } userdb { driver = prefetch } userdb { driver = sql args = /etc/dovecot/dovecot-sql.conf.ext } protocol lda { mail_plugins = autocreate quota mail_log trash virtual notify } 16:04:16 postfix/qmgr[4970]: 8CD6CE072E: from=<user(a)example.com>, size=880, nrcpt=1 (queue active) 16:04:16 dovecot: auth: Debug: master in: USER#0111#011user(a)example.com#011service=lda 16:04:16 dovecot: auth: Debug: prefetch(user(a)example.com): passdb didn't return userdb entries, trying the next userdb 16:04:16 dovecot: auth: Debug: sql(user(a)example.com): SELECT '/path-to-mailboxen/' || virtual_users.home AS home, uid , gid , quota as quota_rule FROM virtual_users WHERE email = 'user(a)example.com' AND status = 'A' 16:04:16 dovecot: auth: Debug: userdb out: USER#0111#011user@example.com#011home=/path-to-mailboxen/example.com/user#011uid=12345#011gid=12345#011quota_rule=*:storage=0 ^^^^^^^^^^^^^^^^^^^^^^ This shows that the database lookup works.

If a folder has new messages, then it has a badge that is dark blue (with the theme I am using) with the number of un-read messages. Otherwise it has a badge that is light-blue to indicate un-read messages only. Folders with no badges have zero un-read messages. So there is definitely a distinction for "new" messages.
