Sieve by the addressee

Hi, everyone! I have a sieve that is supposed to put all messages addressed to this mailing list into a separate folder: if anyof (address :is "to" "ml(a)shadrinden.ru", address :is "to" "dovecot(a)dovecot.org") { fileinto "mail_list"; stop; } Generally, it's working, but today I have got two mailing list messages that weren't put in that folder, they arrived straight into INBOX. I suppose that was because they were replies and were addressed to the person who asked the questions, so they had his address in "To:", and only in "Cc:" they had dovecot(a)dovecot.org. So, am I right that, when filtering messages by the addressee, it's generally a good idea to use not just "to", but ["to", "cc', "bcc"] ? -- Respectfully, Denis Shadrin

Monitoring Dovecot Replication
by MK 19 Feb '21

19 Feb '21

Hello, I have a cluster with two dovecot nodes with dovecot replication between them. The setup works fine and now I'm searching for a way to monitor the users so that I can get an information if the replication fails for one user for a longer time and I have to trigger the replication manually. Most of the time if I see a replication failure the self healing of dovecot replication repairs this in max. 10 min. I have tried different combinations of querying " doveadm replicator status '*' " and search for failed users and then send an alarm if one of fast sync, full sync or success sync reaches a threshold. But there is no combination that seems to be working if I only want to trigger this if I have to fix the replication manualy. Can someone tell me what I have to query to get only the user who's replication failed for a longer time (10 min +) and that I have to fix manually? Thank you. Oliver

Sieve regex error "invalid preceding regular expression"
by ml＠shadrinden.ru 19 Feb '21

19 Feb '21

Hi, everyone! I'm trying to get the detail part of the address (i.e. anything that comes between + and @ in the address of this type: alias+detail(a)mydomain.tld) in this sieve: if address :regex :localpart "to" "\+(.*)" { fileinto :create "${1}"; stop; } However, when I try to compile it with sievec, I get this error: error: invalid regular expression '+(.*)' for regex match: invalid preceding regular expression. Why is that? Shouldn't I escape the plus sign? Itried also not escaping it, but I get the same error. (A note why I don't use "envelope :detail" for that purpose: because the detail part of the address is not preserved in the "Envelope-To" after the message is redirected from alias to user. After that redirection the "Envelope-To" contain only user(a)mydomain.tld, not user+detail(a)mydomain.tld.) -- Respectfully, Denis Shadrin

Dovecot v2.3.14.rc1 released
by Aki Tuomi 18 Feb '21

18 Feb '21

We are pleased to release first release candidate for v2.3.14. We have done changes to packaging so please give us any feedback on how it works. https://dovecot.org/releases/2.3/rc/dovecot-2.3.14.rc1.tar.gz https://dovecot.org/releases/2.3/rc/dovecot-2.3.14.rc1.tar.gz.sig Binary packages in https://repo.dovecot.org/ Docker images are not available for this release candidate. Kind regards, Aki Tuomi Open-Xchange oy --- * Added new aliases for some variables. Usage of the old ones is possible, but discouraged. (These were partially added already to v2.3.13.) See https://doc.dovecot.org/configuration_manual/config_file/config_variables/ for more information. * Optimize imap/pop3/submission/managesieve proxies to use less CPU at the cost of extra memory usage. * Remove autocreate, expire, snarf and mail-filter plugins. * Remove cydir storage driver. * doveadm -D: Add timestamps to debug output even when LOG_STDERR_TIMESTAMP environment variable is not set. Timestamp format is taken from log_timestamp setting. * If BROKENCHAR or listescape plugin is used, the escaped folder names may be slightly different from before in some situations. This is unlikely to cause issues, although caching clients may redownload the folders. * imapc: It now enables BROKENCHAR=~ by default to escape remote folder names if necessary. This also means that if there are any '~' characters in the remote folder names, they will be visible as "~7e". * imapc: When using local index files folder names were escaped on filesystem a bit differently. This affects only if there are folder names that actually require escaping, which isn't so common. The old style folders will be automatically deleted from filesystem. * stats: Update exported metrics to be compliant with OpenMetrics standard. + doveadm: Add an optional '-p' parameter to metadata list command. If enabled, "/private", and "/shared" metadata prefixes will be prepended to the keys in the list output. + doveconf: Support environment variables in config files. See https://doc.dovecot.org/configuration_manual/config_file/config_file_syntax… for more details. + indexer-worker: Change indexer to disconnect from indexer-worker after each request. This allows service indexer-worker's service_count & idle_kill settings to work. These can be used to restart indexer-worker processes once in a while to reduce their memory usage. - auth: "nodelay" with various authentication mechanisms such as apop and digest-md5 crashed AUTH process if authentication failed. - auth: Auth lua script generating an error triggered an assertion failure: Panic: file db-lua.c: line 630 (auth_lua_call_password_verify): assertion failed: (lua_gettop(script->L) == 0). - configure: Fix libunwind detection to work on other than x86_64 systems. - doveadm-server: Process could crash if logging was done outside command handling. For example http-client could have done debug logging afterwards, resulting in either segfault or Panic: file http-client.c: line 642 (http_client_context_close): assertion failed: (cctx->clients_list == NULL). - dsync: Folder name escaping with BROKENCHAR didn't work completely correctly. This especially caused problems with dsync-migrations using imapc where some of the remote folder names may not have been accessible. - dsync: doveadm sync + imapc doesn't always sync all mails when doing an incremental sync (-1), which could lead to mail loss when it's used for migration. This happens only when GUIDs aren't used (i.e. imapc without imapc_features=guid-forced). - lib-imap: imapc parsing illegal BODYSTRUCTUREs with NILs could have resulted in crashes. This exposed that Dovecot was wrongly accepting atoms in "nstring" handling. Changed the IMAP parsing to be more strict about this now. - lib-index: If dovecot.index.cache has corrupted message size, fetching BODY/BODYSTRUCTURE may cause assert-crash: Panic: file index-mail.c: line 1140 (index_mail_parse_body_finish): assertion failed: (mail->data.parts != NULL). - lib-index: Minor error handling and race condition fixes related to rotating dovecot.index.log. These didn't usually cause problems, unless the log files were rotated rapidly. - lib-lua: Lua scripts using coroutines or lua libraries using coroutines (e.g., cqueues) panicked. - Message PREVIEW handled whitespace wrong so first space would get eaten from between words. - FTS and message PREVIEW (snippet) parsed HTML &entities case-sensitively. - lib-mail: When max nested MIME parts were reached, IMAP BODYSTRUCTURE was written in a way that may have caused confusion for IMAP clients and also Dovecot itself when parsing it. The truncated part is now written out using application/octet-stream MIME type. - lib-oauth2: HS512 and HS384 JWT token algorithms crash when you try to use them: Panic: file hmac.c: line 26 (hmac_init): assertion failed: (meth->context_size <= MAC_MAX_CONTEXT_SIZE). - event filters: NOT keyword did not have the correct associativity. NOT a AND b were getting parsed as NOT (a AND b) instead of (NOT a) AND b. - Ignore ECONNRESET when closing socket. This avoids logging useless errors on systems like FreeBSD. - event filters: event filter syntax error may lead to Panic: file event-filter.c: line 137 (event_filter_parse): assertion failed: (state.output == NULL) - lib: timeval_cmp_margin() was broken on 32-bit systems. This could potentially have caused HTTP timeouts to be handled incorrectly. - log: instance_name wasn't used as syslog ident by the log process. - master: After a service reached process_limit and client_limit, it could have taken up to 1 second to realize that more client connections became available. During this time client connections could have been unnecessarily rejected and a warning logged: Warning: service(...): process_limit (...) reached, client connections are being dropped - stats: Crash would occur when generating openmetrics data for metrics using aggregating functions. - stats: Event filters comparing against empty strings crash the stats process.

doveadm import uninterruptable?
by Ralf Hildebrandt 17 Feb '21

17 Feb '21

I'm using % doveadm import -u restore(a)backup.invalid mdbox:/home/archive/mdbox "" mailbox INBOX header From $PATTERN sometimes, I mistype the pattern and immediately try to stop the doveadm command with CTRL-C - and this never succeeds. Is it inentional that I cannot interrupt the "doveadm import" command? Using 2.3.13 here. -- Ralf Hildebrandt Geschäftsbereich IT | Abteilung Netzwerk Charité - Universitätsmedizin Berlin Campus Benjamin Franklin Hindenburgdamm 30 | D-12203 Berlin Tel. +49 30 450 570 155 | Fax: +49 30 450 570 962 ralf.hildebrandt(a)charite.de | https://www.charite.de

imapc settings for specific mailbox / namespaces
by Tobia Grosselle [ Terralink ] 17 Feb '21

17 Feb '21

Hello, Is it possible to use imapc for specific mailbox or namespace? Something like this: namespace Test { list = no type = private inbox = no hidden=no prefix = TEST/ separator = / location = imapc: imapc_host = imap.example.com imapc_password = secret imapc_port = 143 imapc_user = user(a)example.com } or is only intended for general use as general proxy in the global configuration?

Logfile flooding with lookup failure for root user using pam
by Michael Ruiz 16 Feb '21

16 Feb '21

Hi all, I am getting the error where root is constantly being lookedup over imap I am guessing. I am pretty sure services like fail2ban and logwatch are setup to send from another user instead of root @ localhost so I think this may be an imap issue. I tried adding root to /etc/dovecot/deny-users , but this error still persists. I know imap as root is a big security issue and is disabled, but I cannot pinpoint how or why this is happening so often. I am using PAM and passwd for authentication and authorization. How can I prevent root user from being looked up in the first place ? Regards, Michael dovecot[606167]: lmtp(606199): Error: lmtp-server: conn unix:pid=606196,uid=73 [2]: rcpt root@<domain>: Failed to lookup user root@<domain>: Invalid settings in userdb: userdb returned 0 as uid replaced my domain name with <domain> in this example.
