JWT tokens, timestamps and doubles (microseconds)
by Aleš Krajník 14 Feb '22

14 Feb '22

Hi all, I am having troubles with OAuth2 setup with local introspection of JWT tokens. This happens, when the JWT tokens contain timestamps as doubles, with microseconds, for example with the following payload: { "aud": "caf65d650022e3eb7cce518e7526a39f", "jti": "8291efed41d2ce65ec5c59a4cbcaa285f2ca37d5b2785da56de66adbd1b8eef65495bc 599be5ac56", "iat": 1644833538.793359, "nbf": 1644833538.79336, "exp": 1644833838.773605, "sub": "ales(a)example.com", "scope": "email" } Such a … [View More]

wondering if I configured sieve vacation correctly
by Marc 14 Feb '22

14 Feb '22

I have a user who feels compelled to use the vacation as autoreply to confirm that a message has been received. The down side is of course, that if spam/abuse messages get through the spam filters, this can get 'messy'. Currently I am getting these ndr's as postmaster(?). But I was not actually expecting this. I would expect that the mailbox with the autoreply would get this report. The vacation is configured like this[1], my question is. What am I doing wrong that this ndr is not ending up … [View More]

Backup procedures
by Jorge Bastos 13 Feb '22

13 Feb '22

Howdy, I have a particular situation where I have about 5 users using a large account in IMAP, and I have the need to backup the account daily or weekly or so. I was thinking about to copy the whole directory, each email is a file, it could probably work, but the dovecot index files would be damaged/wrong. Is there a tool that could perform a backup (ex: yesterday), and when I inserted that backup, it just insert the emails and folders that were deleted today? Thanks in advanced, Jorge

Hanging doveadm-server processes with dsync replication
by Sebastian Marske 10 Feb '22

10 Feb '22

Dear Dovecot mailing list, after updating Dovecot from 2.3.16 to 2.3.18 on a dsync-replicated server there are hanging doveadm-server processes piling up over time, eventually resulting in some of the affected users being shown as out of sync. Our setup is based on FreeBSD 13, ZFS and Dovecot (we use custom packages built with poudriere) with master/master replication using dsync. However, we use a shared ip (Carp), so that only one server is actually active. Please see the output of "… [View More]doveconf -n" at the end for our config. Starting from an in-sync state, I updated Dovecot on the inactive server. Occasionally, Dovecot logs messages like: Feb 8 15:02:15 myhost dovecot[99800]: doveadm(someuser)<2090><ZLayIal3AmIqCAAADKIhQg>: Error: write(<local>) failed: Timed out after 60 seconds These occur for an increasing number of users (maybe 30 after two days), but not for every user (there are >4800 users on that server) and also only once for every affected user. Here's some more information about the process/user from the log entry: # doveadm replicator dsync-status username type status someuser incremental Waiting for dsync to finish (the type is "incremental for most users, but "normal" and "full" show up as well) # doveadm replicator status someuser username priority fast sync full sync success sync failed someuser low 00:01:51 21:56:06 69:56:10 y (again, not all are in failed state) # top -abp 2090 PID USERNAME THR PRI NICE SIZE RES STATE C TIME WCPU COMMAND 2090 sysdov 1 20 0 26M 15M kqread 12 0:01 0.00% doveadm-server: [<local>] (doveadm-server) (didn't change for >1d) # top -m io -abp 2090 PID USERNAME VCSW IVCSW READ WRITE FAULT TOTAL PERCENT COMMAND 2090 sysdov 363 58 0 271 2 273 0.00% doveadm-server: [<local>] (doveadm-server) (didn't change for >1d) # gdb -p 2090 ...

(gdb) So I guess it's waiting for something that * doesn't happen on my system * or it didn't wait for in 2.3.16 >From what I've seen, mails from the active server (still on 2.3.16) are replicated to this server. For non-affected users, mails are also replicated from this server to the active one. I can't tell about "outgoing" replication for affected users, yet. After downgrading back to 2.3.16, things are fine again. Most affected users jump back to being successfully synced within a couple of minutes. If not, starting replication via doveadm get's them there. Testing 2.3.18 again, it seems that the same users are affected again. I also tested 2.3.17 when it came out and had the same issue, paired with the ioloop issue [1], which was fixed in 2.3.18 and which I don't see anymore. The hanging doveadm processes remain, though. Do you have any suggestions on how to resolve this?

Different handling of upper and lower case while indexing/searching with Solr

Outlook 2019 and push notifications
by Laura Smith 10 Feb '22

10 Feb '22

Is there some secret config sauce I'm unaware of to get IMAP push notifications working with Outlook ? My present situation is that non-Outlook users (e.g. Apple iOS, Apple Mail etc.) work perfectly with the config below. New emails get pushed, deletes get reflected, all is happy in the world. But with Outlook nothing. You send a user an email, nothing happens in their inbox until you manually refresh by checking for new mails or waiting for the auto-check to kick in (sometimes switching … [View More]between IMAP folders also does the trick). I know Outlook has a long history of being a mess when it comes to standards compliance, but surely it can't be this bad ? doveconf -n : # 2.3.18 (9dd8408c18): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.18 (0bc28b32) # OS: Linux 5.10.0-11-amd64 x86_64 Debian 11.2 xfs # Hostname: foobar.example.com auth_verbose = yes auth_verbose_passwords = sha1:7 doveadm_password = # hidden, use -P to show it imap_capability = +SPECIAL-USE imapc_features = rfc822.size fetch-headers fetch-bodystructure imapc_port = 993 imapc_ssl = imaps mail_location = maildir:/foo_data/mail/%d/%n/Maildir mail_plugins = notify replication push_notification managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date index ihave duplicate mime foreverypart extracttext imapsieve vnd.dovecot.imapsieve namespace inbox { inbox = yes location = mailbox "Deleted Messages" { auto = no special_use = \Trash } mailbox Drafts { special_use = \Drafts } mailbox Junk { auto = subscribe special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { args = /etc/dovecot/local_sql_users.conf driver = sql } plugin { imapsieve_mailbox1_before = file:/etc/dovecot/imap_sieve/spam.sieve imapsieve_mailbox1_causes = COPY imapsieve_mailbox1_name = Junk imapsieve_mailbox2_before = file:/etc/dovecot/imap_sieve/ham.sieve imapsieve_mailbox2_causes = COPY imapsieve_mailbox2_from = Junk imapsieve_mailbox2_name = * sieve = file:~/sieve;active=~/.dovecot.sieve sieve_global_extensions = +vnd.dovecot.pipe +vnd.dovecot.environment sieve_pipe_bin_dir = /etc/dovecot/imap_sieve sieve_plugins = sieve_imapsieve sieve_extprograms } protocols = imap lmtp sieve service auth { unix_listener /var/spool/postfix/private/dovecot-auth { group = postfix mode = 0660 user = postfix } vsz_limit = 2 G } service doveadm { inet_listener { port = 11867 ssl = yes } } service imap-login { process_min_avail = 5 service_count = 1 } service lmtp { process_min_avail = 5 unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0660 user = postfix } user = foo_virtmail } service managesieve-login { inet_listener sieve { port = 4190 } inet_listener sieves { address = port = 5190 ssl = yes } } ssl = required ssl_ca = </etc/foobar/ssl/certificates/_.example.com.issuer.crt ssl_cert = </etc/foobar/ssl/certificates/_.example.com.crt ssl_cipher_list = ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:DHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384 ssl_dh = # hidden, use -P to show it ssl_key = # hidden, use -P to show it ssl_prefer_server_ciphers = yes userdb { args = /etc/dovecot/local_sql_users.conf default_fields = uid=foo_virtmail gid=foo_virtmail home=/foo_data/mail/%d/%n driver = sql } protocol lmtp { mail_plugins = notify replication push_notification sieve postmaster_address = foo(a)foobar.com } protocol lda { deliver_log_format = msgid=%m: %$ mail_plugins = notify replication push_notification sieve postmaster_address = postmaster quota_full_tempfail = yes rejection_reason = Your message to <%t> was automatically rejected:%n%r } protocol imap { mail_max_userip_connections = 20 mail_plugins = notify replication push_notification imap_sieve } [View Less]

Certificate and showing a sign-cert not there

Hi - I am running Postfix 3.6.4 with Dovecot 2.3.17.1 (476cd46418). I have a multi-signed cert from Entrust. The cert works fine on port 25.

Config for filtering (ignoring) specific mbox mail folders?
by John Hardin 08 Feb '22

08 Feb '22

Folks: I'm migrating to Dovecot to provide IMAP services for my personal network. I have more than a couple of decades of mail in multiple (1000+) mbox mail files, but I don't care to expose all of those to IMAP. Is there any way to filter out what mail folders Dovecot will LIST and provide access to using globs or regular expressions? I'd prefer to avoid rearranging the mbox files (e.g. to subdirectories) if possible. I looked through the Dovecot documentation and didn't see anything … [View More]

sieve: destination folder lookup in database?

Hi, is there a way to lookup the action for an incoming mail, especially which folder to move the mail in, in a database? Given Problem: I want to replace the mda mailfilter/maildrop with dovecot/sieve.

Hello, as I need a mailbox locally only just for filtering, I've tried to manually create it (using Maildir as backend): 1. Created a folder in the appropriate location under /home/vmail with subfolders cur, new, tmp. 2. Set the same user:group as for the other folders (i.e. vmail:vmail). 3. Restarted Dovecot and Email-Client (Thunderbird). However, I cannot subscribe to the new folder. What am I missing here? Kind regards, Peter

Dovecot v2.3.18 released
by Aki Tuomi 03 Feb '22

03 Feb '22

Hi all! We are pleased to release v2.3.18 of Dovecot. Debian/Stretch support has now been dropped. CentOS 8 packages have been replaced with RedHat Enterprise Linux 8 packages. These should be compatible with all the various variants. https://dovecot.org/releases/2.3/dovecot-2.3.18.tar.gz https://dovecot.org/releases/2.3/dovecot-2.3.18.tar.gz.sig Binary packages in https://repo.dovecot.org/ Docker images in https://hub.docker.com/r/dovecot/dovecot Regards, Aki Tuomi Open-Xchange oy -- … [View More]* Removed mail_cache_lookup_finished event. This event wasn't especially useful, but it increased CPU usage significantly. * fts: Don't index inline base64 encoded content in FTS indexes using the generic tokenizer. This reduces the FTS index sizes by removing input that is very unlikely to be searched for. See https://doc.dovecot.org/configuration_manual/fts/tokenization for details on how base64 is detected. Only applies when using libfts. * lmtp: Session IDs are now preserved through proxied connections, so LMTP sessions can be tracked. This slightly changes the LMTP session ID format by appending ":Tn" (transaction), ":Pn" (proxy connection) and ":Rn" (recipient) counters after the session ID prefix. + Events now have "reason_code" field, which can provide a list of reasons why the event is happening. See https://doc.dovecot.org/admin_manual/event_reasons/ + New events are added. See https://doc.dovecot.org/admin_manual/list_of_events/ + fts: Added fts_header_excludes and fts_header_includes settings to specify which headers to index. See https://doc.dovecot.org/settings/plugin/fts-plugin#plugin-fts-setting-fts-h… for configuration details. + fts: Initialize the textcat language detection library only once per process. This can reduce CPU usage if fts_languages setting has multiple languages listed and service indexer-worker { service_count } isn't 1. Only applies when using libfts. + lib-storage: Reduced CPU usage significantly for some operations that accessed lots of emails (e.g. fetching all flags in a folder, SORT, ...) + lib: DOVECOT_PREREQ() - Add micro version which enables compiling external plugins against different versions of Dovecot. + lmtp: Added new lmtp_verbose_replies setting that makes errors sent to the LMTP client much more verbose with details about why exactly backend proxy connections or commands are failing. + submission: Support implicit SASL EXTERNAL with submission_client_workarounds=implicit-auth-external. This allows automatically logging in when SSL client certificate is present. - *-login: Statistics were disabled if stats process connection was lost. - auth: Authentication master user login fails with SCRAM-* SASL mechanisms. - auth: With auth_cache_verify_password_with_worker=yes, passdb extra fields in the auth cache got lost. - doveadm: Fixed crash if zlib_save_level setting was specified, but zlib_save was unset. v2.3.15 regression. - doveadm: Proxying can panic when flushing print output. v2.3.17 regression. Fixes: Panic: file ioloop.c: line 865 (io_loop_destroy): assertion failed: (ioloop == current_ioloop) - doveadm: stats add --group-by parameter didn't work. - fts: Using email-address fts tokenizer could result in excessive memory usage with garbage email input. This could cause the indexer-worker processes to fail due to reaching the VSZ memory size limit. Only applies when using libfts. - imap: A SEARCH command timing out while fts returns indexes may timeout returning "NO [SERVERBUG]", while it should return "NO [INUSE]" instead. - imap: LIST-EXTENDED doesn't return STATUS for all folders. Sending LIST .. RETURN (SUBSCRIBED STATUS (...)) did not return STATUS for folders that are not subscribed when they have a child folder that is subscribed as mandated by IMAP RFCs. - imapc: Mailbox vsize calculation crashed with Panic: file index-mailbox-size.c: line 344 (index_mailbox_vsize_hdr_add_missing): assertion failed: (mails_left > 0) - indexer: If indexer-worker crashes, the request it was processing gets stuck in the indexer process. This stops indexing for the folder until indexer process is restarted. v2.3.14 regression. - indexer: Process was slowly leaking memory for each indexing request. - lib-event: Unnamed events were wrongly filtered out for event/metric filters like "event=abc OR something_independent_of_event_name". - lib-index: 64-bit big endian CPUs handle last_used field in dovecot.index.cache wrong. - lib-ssl-iostream: Fix buggy OpenSSL error handling without assert-crashing. If there is no error available, log it as an error instead of crashing. The previous fix for this in v2.3.11 was incomplete. Fixes Panic: file istream-openssl.c: line 51 (i_stream_ssl_read_real): assertion failed: (errno != 0) - lmtp: Out-of-memory issues can happen when proxying large messages to LMTP backend servers that accept the message data too slow. - master: HAProxy header parsing has read buffer overflow if provided header size is invalid. This happens only if inet_listener { haproxy=yes } is configured and only if the remote IP address is in haproxy_trusted_networks. - old_stats: Plugin kept increasing memory usage, which became noticeable with long-running imap sessions. - stats: Dynamically adding same metric multiple times causes multiple stats. - submission-login: Authentication does not accept OAUTH2 token (or other very long credentials) because it considers the line to be too long. - submission-login: Process can crash if HELO is pipelined with an invalid domain. - submission-proxy: Don't use SASL-IR if it would make the AUTH command line longer than 512 bytes. - submission: Service would crash if relay server authentication failed. - virtual: FTS search in a virtual folder could crash if there are duplicate mailbox GUIDs. This mainly happened when user had both INBOX and INBOX/INBOX folders and the namespace prefix was INBOX/. Fixes Panic: file hash.c: line 252 (hash_table_insert_node): assertion failed: (opcode == HASH_TABLE_OP_UPDATE) - virtual: If mailbox opening fails, the backend mailbox is leaked and process crashes when client disconnects. Fixes Panic: file mail-user.c: line 232 (mail_user_deinit): assertion failed: ((*user)->refcount == 1) - virtual: Searching headers in virtual folders didn't always use full-text search indexes, if fts_enforced=no or body.

How to use virtual "All" and "Flagged" mailbox?
by A B 01 Feb '22

01 Feb '22

Hello, I'm trying to use the virtual "All" and "Flagged" mailboxes as described in 15-mailboxes.conf. The information here ( https://doc.dovecot.org/configuration_manual/virtual_plugin/) doesn't really touch on how to actually interact with the virtual mailboxes. My presumption is that when I mark an email message in the Inbox as FLAGGED (and I can confirm the \Flagged flag has been set) then I should then be able to either (1) see a copy of that message in the virtual.Flagged folder, or (2) … [View More]when I use an imap command to get the message nums or whatever from the virtual.Flagged folder/mailbox, it should return the message that is flagged in the inbox as a result. Additionally, I'm presuming that for each new user that automatically gets added, I would have to create my own script that would add the dovecot-virtual file, dovecot doesn't do that on its own.

Quota: read how much diskspace is available?
by Hans van Zijst 01 Feb '22

01 Feb '22

Hi, I've been trying to get domain quotas to work for a while, but to no avail so far. Is there a way to let Dovecot simply check how much space is still available in a directory? I'm using GlusterFS as my mailstore, so I can configure quotas per directory. All I need is a way to let Dovecot check quota in a way like "df /var/vmail/<domain>". Kind regards, Hans

Set mail crypt private password with OAUTH?
by Max Kostikov 31 Jan '22

31 Jan '22

We currently use Dovecot and mailbox encryption via the mail-crypt-plugin. With standard password authentication, we set the value of the individual password to encrypt the contents of the userdb_mail_crypt_private_password mailbox in the SQL query. Is it possible to set the userdb_mail_crypt_private_password value when authenticating via OAUTH2 ? -- Best regards, Max Kostikov

PLAIN password scheme issue with {}
by Kris von Mach 31 Jan '22

31 Jan '22

Hello, Using PLAIN password scheme and a user having a password with {} for example {RnDR8DaD} causes the authentication to fail: auth-worker(85632): Error: conn unix:auth-worker (uid=143): auth-worker<3333>: sql(user(a)domain.com,123.45.68.78,<EBh0ouPWULvTF5AQ>): Unknown scheme RnDR8DaD Is there some sort of a workaround for this other than requesting user not to use {} at beginning and end of their password?

Dsync replication - delayed replication (Sync lock)
by Daniel Botting 31 Jan '22

Hi, *Our setup:* Two Debian 10 machines that are setup to replicate mail between them, we have round robin DNS setup so a user can connect to either server. *What should happen:* Mail is delivered to either server and replicated across straight away to their mailbox on the other server so it does not matter which one they are connected to they will receive it fairly soon after delivery. *What actually happens:* In some instances the user will experience a delayed receipt of messages … [View More]if they are not connected to the server that the message is initially delivered to, sometimes the delay is 5/10 minutes, we had a recent support ticket submitted where it was over an hour.

Non-unique Message ID in mail messages
by Daniel Ryšlink 28 Jan '22

28 Jan '22

Hello! I apologize for bringing perhaps trivial/well-known matter, but I am interested in your opinion. RFC 5322 clearly states that mail messages SHOULD contain a Message ID identifier, but if the do contain it, it MUST be globally unique. Despite this requirement, I have encountered senders (namely Spamcop) that sends obviously different (albeit related) messages called "Alert" and "Summary" (they are always related to the same incident and have the same Message ID). This creates all … [View More]

hi Christian >Did the password hash algorithm change between devuan 3 and 4? >You can check that in your /etc/shadow file. As I understand, devuan is pretty much debian without systemd? And that if you were prepared to do a fair bit of work you could start with debian installed, hack it about and end up with something like devuan? I doubt devuan has done anything to deviate from debian at this level and both machines were recently dist-upgraded. Dovecot needed no tinkering with at all … [View More]

doveadm backup : Warning: Deleting mailbox GUID= is missing locally

Hi, As per the docs (https://wiki.dovecot.org/Tools/Doveadm/Sync) I'm presently running doveadm backup multiple times with a view to eventual server migration. I am seeing messages such as this: Warning: Deleting mailbox 'Junk': UID=1826 GUID= is missing locally Is it anything to worry about ? If so, how should I be dealing with it. I also have a further question. It is not clear from the docs what the role of the "-R" flag is in relation to "doveadm backup" ? Surely by definition backup = … [View More]

I've created a user on both server A and server B, test(a)domain.tld On server A, host parameter in password_query for test(a)domain.tld is set to server B's address, and proxy_maybe is enabled. … [View More]

hi Christian Same user and password on both machines, users with shell accounts; exactly the same; in fact I'm struggling to see anything different that might be relevant. On one machine dovecot just works on the other, it stopped working after a dist-upgrade. One machine (where it works) is a debian 11 VPS, the other is real PC hardware running devuan 4, but their dovecot is a debian package. I can't see why either of that should matter and dovecot also just worked on the PC with devuan 3. … [View More]I've tried purging dovecot-core and dovecot-imapd and reinstalling to no effect. > > 1.
