Submission: track authenticated_user
by itanguy＠univ-brest.fr 10 Nov '22

10 Nov '22

Hello, We would like to use Dovecot Submission to have less queues to maintain. The relayhost (Postfix) after Dovecot routes mail by sender_map, so authenticated user, not the "mail from" because . For what we've seen, we can't use receive header to retrieve this authenticated_user. Example of header : Received: from mailhost ([0.0.0.0]) by submission.host with ESMTPSA id submission-id (envelope-from<myadress(a)example.com>) for<myadress(a)example.com>;… [View More]

Help with configuration?
by Ellie McNeill 10 Nov '22

10 Nov '22

Hi, I'm running my own mail server on Debian 11 with exim and Dovecot 2.3.13. I have it working, but I'm seeking advice on further customising my setup. I'm using the Maildir++ format with some personal folders. I use IMAP to retrieve mail and Dovecot's submission server to send mail. 1. I want to have incoming emails automatically placed in certain folders instead of 'Inbox' based on certain criteria. For example, I want all emails from PayPal to go into the 'PayPal' folder and all … [View More]

Someone has probably already replied to this, but it's a typo: the OP wanted to say "store". The certificate you created was used to sign itself ("self signed") and thus, asserts its own validity. If you need *other* people to trust your SSL service, you should sign your certificate … [View More]

doveadm backup|sync works for every folder but INBOX
by Ralf Becker 09 Nov '22

09 Nov '22

I'm trying to migrate an old Cyrus 2.5 server to Dovecot 2.3.19 using doveadm backup -R, which works for all folders but the INBOX itself, which always stays empty. The Cyrus side uses altnamespace:no and unixhierarchysep:no, it's used as imapc: remote in doveadm backup -R with imapc_list_prefix=INBOX Dovecot uses the following namespace to migrate into: namespace inboxes { inbox = yes location = mailbox Sent { auto = subscribe &… [View More]nbsp; special_use = \Sent } ### some more folders omitted ### prefix = INBOX/ separator = / subscriptions = no } I use the following command line for the migration: doveadm -o imapc_features='rfc822.size fetch-headers' -o mail_prefetch_count=20 -o namespace/subs/location=mbox:/var/dovecot/subs -o imapc_user='someuser' -o imapc_password='secret' -o imapc_host=<cyrus-ip> -o imapc_list_prefix=INBOX -D backup -f -n INBOX/ -R -u someuser@somedomain imapc: The debug output contains the following lines: Nov 02 10:16:01 dsync(someuser@somedomain): Debug: brain S: Namespace INBOX/ has location imapc: Nov 02 10:16:01 dsync(someuser@somedomain): Debug: brain M: Local mailbox tree: INBOX guid=d8d5a3122bce5f63ef9101001ebfc848 uid_validity=1667223083 uid_next=1 subs=no last_change=0 last_subs=0 Nov 02 10:16:01 dsync(someuser@somedomain): Debug: brain S: Local mailbox tree: INBOX guid=c92f64f79f0d1ed01e6d5b314f04886c uid_validity=1577952633 uid_next=32691 subs=no last_change=0 last_subs=0 Nov 02 10:16:28 dsync(someuser@somedomain): Warning: Mailbox changes caused a desync.

In a tcpdump of the IMAP trafic I can see a STATUS "INBOX" (UIDNEXT UIDVALIDITY) but no EXAMINE "INBOX" or something else I would expect from the sync. I can provide the full output of doveadm backup/sync and a pcap of the IMAP trafic, but not to the public list. Any idea what's wrong with the sync of the INBOX or other suggestions / imapc parameters to use?

"Mailbox isn't a valid MBOX file" Error
by Elise 06 Nov '22

06 Nov '22

Running currently two local mailclients: Outlook 2021 and Thunderbird 102.4.2 When using TB and remove a message on my main account, I get this error: [CANNOT] Mailbox isn't a valid mailbox On any other TB configured email accounts I can remove messages without any problems. First I thought that Outlook might block removal on messages, but the issue appears as well if I close that mail client. Can you tell what is causing this problem? Best regards, Jos Chrispijn

Any update on lazy load SNI?
by Pierre Allétru 03 Nov '22

03 Nov '22

Hi folks, We need to use SNI with Dovecot at a relatively large scale and I was wondering if there's any update on the ability to: 1 - Lazy load SNI certificates when they are needed instead of loading them all at once during startup/reload, thus taking a lot of memory and being very slow. 2 - Not having to reload Dovecot every time a new domain cert is added in conf. 3 - Or at least have Dovecot keep processing clients while the slow reload happens. This has been asked already in a 2016 … [View More]

Dovecot does not start on MacOS Monterey

Hi, this is a duplicate of the "Dovecot does not start on MacOS Monterey 12.01" thread. I’m still seeing this on dovecot 2.3.19.1. Is there a recommended workaround? The last post in that thread indicated that some modifications in `./src/lib/restrict-process-size.c` might be necessary. Best regards Doro

Change password schema and post-login script

Hello, Question #1: For version 2.3.19.1 these commands use BLF-CRYPT, right? doveadm pw doveadm pw -s CRYPT Question #2: I want to change password schema for current users.

dovecot mailing list (this mailing list), DKIM, SPF and DMARC
by Lev Serebryakov 22 Oct '22

22 Oct '22

My domain (serebrtyajov.spb.ru) has all these "new" e-mail technologies configured. It works fine till I write to this mailing list. After that I've got several DMARC reports about "spam" from my domain. All these reports are about my mailing list post. I don't have such problems with other mailing lists (FreeBSD ones, OpenJDK ones, and others). Looks like mailing list software for this mailing list is misconfigured. I'm sure, I'll get new after this message. -- // Black Lion AKA Lev Serebryakov

mdbox vs. maildir format
by Michael 19 Oct '22

19 Oct '22

hey, i am considering changing my mailbox format from maildir to mdbox. the reason for this is mainly, b/c i have (a) multiple large mailboxes with tens of thousands of mail files, and (b) most of these mails files have a size significantly smaller than the sector size of the disk. so, since the emails themselves are only about nGB large, the disk space used is at least twice as much, if not even three times. i know, hard disk space is 'cheap', but still... but then i read at https://… [View More]

Unseen field reported by imap status command returns wrong count for shared mailboxes on dovecot cluster
by Nikolaos Pyrgiotis 19 Oct '22

19 Oct '22

Hello, We recently migrated our mail server to a dovecot cluster of 5nodes, a dovecot proxy, 2directors and 2dovecot backends. All dovecot nodes run version 2.19.1. We use a glusterfs mounted volume on the backends forthe mail storage. We noticed that when issuing the IMAP command to check forUNSEEN messages formails on the shared namespace instead of seeing the value of the unseen messages of the user that the mailbox has been shared to, the value of the unseen messages of the owner of the … [View More]mailbox is returned. This behavior causes thunderbird when getting new messages forshared mailboxes, to show briefly all messages of the mailbox as unseen forthe user before showing the correct unseen count forthe shared mailbox. The mail location of the shared mailboxes is defined with imapc storage type as described inthe documentation. Is this a dovecot bug? Can we configure a different dovecot configuration setting so that imap status command reports the correct unseen field count when mail location is an imapc storage location? An examples is given below when running doveadm command from one the 2 dovecot directors: When issuing the status command we see that the unseen count is 2: root@doved0-rmt0-cn1:/etc/cron.d# doveadm mailbox status -u npyrgiotis all shared.sysadmins doveadm(npyrgiotis): Info: remote(10.101.0.71:8080): doveadm(npyrgiotis(a)domie02.com)<19078><9l8IJTb+GWOGSgAAEU9A+w>: imapc(10.101.0.75:143): Connected to 10.101.0.75:143 (local 10.101.0.71:33476) shared.sysadmins messages=2 recent=0 uidnext=3 uidvalidity=1662640492 unseen=2 highestmodseq=3 vsize=3950 guid=c92f64f79f0d1ed01e6d5b314f04886c firstsaved=1662643853 shared.sysadmins messages=2recent=0uidnext=3uidvalidity=1662640492unseen=2highestmodseq=3vsize=3950guid=c92f64f79f0d1ed01e6d5b314f04886c firstsaved=1662643853 But when fetching the emails of the mailboxes we can see that the \Seen flag is set for both emails root@doved0-rmt0-cn1:/etc/cron.d# doveadm fetch -u npyrgiotis flags mailbox shared.sysadmins ALL doveadm(npyrgiotis): Info: remote(10.101.0.71:8080): doveadm(npyrgiotis(a)domie02.com)<19074><e7rWDgj+GWOCSgAAEU9A+w>: imapc(10.101.0.75:143): Connected to 10.101.0.75:143 (local 10.101.0.71:38750) flags: \Seen flags: \Seen Below i post the dovecot configuration of one of the two dovecot backends: #

Again, a bit more reading got me to adding this to my passdb config: username_filter = *(a)domain-a.com This way, I can control which domains get to authenticate via my ldap backend, which gives me time to design a good way of saving other attributes there.

what are the options to 'interact' with a dovecot imap user
by Marc 14 Oct '22

14 Oct '22

I am looking for a user friendly way to have a user to tell the 'server' to either store or remove an email address. a. My first thought was to use imapsieve for this and have an imap sieve plugin store/remove the email address of the message that is being dragged into a predefined monitored folder. This would work with any imap client b. I was thinking about the message Flagged[1]. I am curious how would I be able to detect this (in sieve)? This does not seem to be stored in the source of … [View More]

One-off backup
by Ian Evans 11 Oct '22

11 Oct '22

I run a small email server for me and the missus. Six dovecot users. Our host is migrating our server instance. They usually (99.9999% lol) go off without a hitch. As we don't have dovecot running elsewhere, I'm assuming doveadm is the wrong tool. If we want to make a one-off backup prior to the migration, is shutting down postfix and running tar czf mailstorage.tgz /path/to/mail okay? Thanks.

Static build problems
by Jacob Welsh 09 Oct '22

09 Oct '22

I'm attempting to build the latest Dovecot, version 2.3.19.1, on Gales Linux, a distribution based on musl libc with all static linking. After working around some expected troubles to generate configure, such as the libtool and iconv.m4 dependencies, the build appeared to complete successfully. But on closer inspection, the plugins were installed as a bunch of .a and .la files rather than getting linked into any of the binaries, as would be necessary to actually use them. I determined … [View More]that the probe for dynamic module support (DOVECOT_MODULES defined in 'm4/modules.m4') had returned a false positive: in the static configuration musl includes a stub dlopen() that always returns failure at runtime, so a compile-and-link-only test is not predictive. Libtool itself is affected in the same way, but it comes with the --disable-shared option which usually makes things works fine. Short of a proper solution (perhaps removing modules.m4 and going instead by what libtool already determined, since you've decided to depend on it anyway), I stubbed out modules.m4 to simply return the correct result for this platform, thus: AC_DEFUN([DOVECOT_MODULES], [ have_modules=no AC_SUBST(MODULE_LIBS) AC_SUBST(DLLIB) ]) Now the build is failing due to the absence of a function that's defined only when HAVE_MODULES is true: libtool: link: gcc -I../../src/lib -I../../src/lib-test -I../../src/lib-ssl-iostream -DDCRYPT_MODULE_DIR=\"/gales/pkg/dovecot-0.0-2.3.19.1/lib/dovecot\" -DDCRYPT_SRC_DIR=\"../../src/lib-dcrypt\" -std=gnu99 -g -O1 -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=2 -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -fno-builtin-strftime -Wstrict-aliasing=2 -Wl,--whole-archive -Wl,../lib-ssl-iostream/.libs/libssl_iostream.a -Wl,--no-whole-archive -o test-stream test_stream-dcrypt.o test_stream-istream-decrypt.o test_stream-ostream-encrypt.o test_stream-test-stream.o ../lib-ssl-iostream/.libs/libssl_iostream.a ../lib-test/.libs/libtest.a ../lib/.libs/liblib.a test_crypto-dcrypt.o: In function `dcrypt_initialize': /home/user/gales-linux/gports/dovecot/build/dovecot-2.3.19.1/src/lib-dcrypt/dcrypt.c:34: undefined reference to `module_dir_try_load_missing' collect2: error: ld returned 1 exit status make[3]: *** [Makefile:664: test-crypto] Error 1 I noticed commit d21897832a443d139d56b1fb1c86d8f76e5f77f3 from 2009, "Fixed compiling without module support", and clearly it's supposed to work since the #ifdefs are there, but I begin to suspect that nobody's actually tested this branch of the configuration tree recently. Further, looking through the automakefiles I'm not finding how the plugin libraries are supposed to work at all in this case and I begin to fear that they simply... aren't. Say it ain't so?

Using sqlite as dict for last_auth plugin
by Oleg petol 04 Oct '22

04 Oct '22

Hi! It is required to collect statistics about the time of the last IMAP and POP3 login of the user and the delivery of letters to him via lmtp. The last-login plugin is perfect. But I don't want to use heavy databases as the mail system service is served by the Oracle DB. The most suitable option, as I see, is to store statistics in the sqlite DB, but after going through all the options in the configuration file, I could not use sqlite. When writing in configuration: plugin { driver=… [View More]sqlite last_login_dict = sqlite:statsdb last_login_key = last-login/%s/%u/%r last_login_precision = ms } I am getting an error: Oct 4 17:01:41 nms4 dovecot: imap(new_ver_test(a)test2.aroma.ru)<154597><q0VJ5jXq9o4KAQDI>: Error: last_login_dict: dict_init(sqlite:statsdb) failed: Unknown dict module: sqlite I did the last-login plugin setup exactly according to the instructions: https://doc.dovecot.org/configuration_manual/mail_location/obox/last_login_… I am using standard debian packages. Desperate, I built latest dovecot version from source, but got exactly the same error. Tell me, please, is it possible to use a dictionary in sqlite format to collect last-login plugin statistics?

Good Morning Michael, No problem. Although, to be clear I didnt point out anything, but its Sébastien and the credit shall go for him. Also, by the way in EXIM MTA, there is verify syntax condition in data acl, which checks all email headers and validate that they are standards compliant and reject sending any email beforehand to your issue which has non-compliant header and offers the ability to remove such headers with condition handling e.g. if contained any Sieve header, to request removing message id headers with headers_remove and add compliant one with add_header, and I guess this will mitigate any mail service provider rejection issue. If you are postfix user and considering switching, let me know, I might be able to help. Zakaria. [View Less]

Since there are changing sections that are different for each email, I can't use that. I wanted to match the stuff … [View More]

new feature: sieve forward plugin
by Marc 26 Sep '22

26 Sep '22

As this page[1] describes a more often occurring problem of forwarding messages from servers that are not included in the spf records. Maybe there should be a plugin that offers this forward functionality. Something like get the spf records of the sender check if there is a -all then apply the sender substitution. https://doc.dovecot.org/configuration_manual/sieve/configuring_auto_forward…
