Accessing Shared Mailbox not working
by Quiwy 15 Nov '22

15 Nov '22

Hi, I'm new on this mailing list and I'm struggling with the configuration of shared mailboxes. I've followed the following documentation page : https://doc.dovecot.org/configuration_manual/shared_mailboxes/shared_mailbo… and manage to had it working for something like 2 minutes, but then changed a parameter and can't get it back working (and of course I don't remember which one it was). I'm using dovecot 2.3.13 . user@hostname:~# dovecot -n # 2.3.13 (89f716dc2): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.13 (cdd19fe3) # OS: Linux 5.10.0-19-amd64 x86_64 Debian 11.5 # Hostname: hostname auth_mechanisms = plain login dict { acl = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } mail_debug = yes mail_home = /var/vmail/%d/%n mail_location = maildir:~/ mail_plugins = acl mail_privileged_group = mail 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 namespace { list = yes location = maildir:/var/mail/vmail/%%d/%%n/Maildir:INDEXPVT=/var/mail/vmail/%%d/%%n/Maildir/shared/%n prefix = shared/%%u/ separator = / subscriptions = no type = shared } 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 = separator = / type = private } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { acl = vfile acl_shared_dict = proxy::acl sieve = file:~/sieve;active=~/.dovecot.sieve } protocols = " imap sieve" service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { mode = 0600 user = vmail } user = dovecot } ssl_cert = </etc/letsencrypt/live/domain/fullchain.pem ssl_client_ca_dir = /etc/ssl/certs ssl_dh = # hidden, use -P to show it ssl_key = # hidden, use -P to show it userdb { args = uid=vmail gid=vmail home=/var/mail/vmail/%d/%n driver = static } protocol imap { mail_plugins = acl imap_acl imap_acl } protocol lda { mail_plugins = acl sieve } This is the content of dovecot-dict-sql.conf.ext : cat dovecot-dict-sql.conf.ext # This file is commonly accessed via dict {} section in dovecot.conf connect = host=localhost dbname=my_dbname user=my_admin_db_user password=my_password map { pattern = shared/shared-boxes/user/$to/$from table = user_shares value_field = dummy fields { from_user = $from to_user = $to } } map { pattern = shared/shared-boxes/anyone/$from table = anyone_shares value_field = dummy fields { from_user = $from } } Now, I have configured some rigth through SOGo interface as I need to use it.

insert lookup post read write write-deleted write-seen This this the output I have from journalctl -f command with debug enabled when trying to access to the shared folder within SOGo : Nov 15

R: Dovecot 2.3 shared namespace issues
by Stefano Cecconello 15 Nov '22

15 Nov '22

Hello, My bad, the OS was ubuntu 20.04 and not 22.04 . After further tinkering\testing, it seems that removing the " acl_ignore_namespace = shared/* " setting did the trick, now we're getting the correct ACL on client side . Without it we can see the folder with the right permissions : Logging as user01 : shared\Sharer01\INBOX : '[NONEXISTENT] Mailbox doesn't exist: shared/test.imapsharer01(a)td01.testdomain.it/INBOX'' shared\Sharer01\subfolder01 ( RW ) : 'shared/test.imapsharer01(a)td01.testdomain.it/subfolder01 test.imapuser01(a)td01.testdomain.it akxeilprwtscd '] shared\Sharer01\subfolder02ro ( RO ) : '[NOPERM] You lack administrator privileges on this mailbox' Logging on Thunderbird and other IMAP clients ( sylpheed\claws ) as user01 : - It list correctly the shared folders as subscribed folders ; - can't view the mail contents of the sharer INBOX, as desired ; - show the total elements of the sharer INBOX, even if the user01 didnt have access ; If the config is correct, this is somehow what we're trying to accomplish, i have some concerns regarding how it is possible to show the total messages of the remote INBOX without having any privileges . Maybe is something related to the index of that INBOX folder that is somewhat read by the accessing user even if IMAP-wise didnt have any ACL \ rights . I still dont understand why enabling the acl_ignore_namespace setting, results in a : - remote INBOX full control, even if it was not defined in any acl ; - subfolders ACL applied correctly Hope that someone can shed a light on it . Thanks Stefano

Re: bug: ARGON2 hash selection incompatible with LDAP
by Krisztián Szegi 15 Nov '22

15 Nov '22

Sorry, I wanted to post from this alias, but From-Address isn't saved with my drafts :) I failed to recognize during my patchwork that the verification function is the same for ARGON2I and -ID: both call `verify_argon2`, which in turn calls `libsodium's crypto_pwhash_str_verify`. In the new light this, there is no "harm" in my patch: - If backend gives back "{ARGON2}...", dovecot verifies with the same call anyway, regardless of what subtype it actually is, i.e.: {ARGON2I} will work too. - If dovecot generates the hash, the prefix will be the one set by the config's default hash, so for backwards comp., "{ARGON2ID}" could be used if someone wants that. Dovecot will succeed in verifying {ARGON2} generated by itself as well.

Dovecot 2.3 shared namespace issues
by Stefano Cecconello 15 Nov '22

15 Nov '22

Hello, We're trying to configure the shared mailbox feature\namespace on a dovecot 2.3 installation . OS : Ubuntu 22.04 x64 Dovecot : 2:2.3.19.1-2+ubuntu20.04 Our test enviroment is based on a dovecot frontend ( director + proxy ) and a dovecot backend ( auth and storage ), later we will think about increasing the number of backends and frontends ( if we got it right, as we plan to use multiple backends, we should use imapc in order to bind the sharer and the accessing user to the same backend ) . On dovecot backend we've configured the new shared namespace, as stated in the documentation ( https://doc.dovecot.org/configuration_manual/shared_mailboxes/shared_mailbox es/#user-shared-mailboxes ) : -- Dovecot conf -------------------- # Maildir's location is under home dir, which is returned by userdb. mail_location = maildir:~/Maildir:VOLATILEDIR=/tmp_lock/%2.256Nu/%u # Quota, mail_log plugins enabled everywhere mail_plugins = quota notify acl fts fts_lucene mail_log mailbox_alias virtual # Default namespace namespace { hidden = no inbox = yes location = prefix = separator = / type = private mailbox Sent { special_use = \Sent auto = create } mailbox Trash { special_use = \Trash auto = create } mailbox Drafts { special_use = \Drafts auto = create } mailbox SPAM { special_use = \Junk auto = create } } # namespace used by virtual search namespace { prefix = VrtSearch. separator = / location = virtual:/etc/dovecot-common-backend/virtual:INDEX=~/virtual hidden = yes subscriptions = no inbox = no list = no } # IMAP SHARING FEATURE service dict { unix_listener dict { mode = 0600 user = vpopmail group = vchkpw } } plugin { acl = vfile acl_ignore_namespace = shared/* acl_shared_dict = proxy::acl-mysql } dict { acl-mysql = mysql:/etc/dovecot-common-backend/dovecot-dict-sql.conf.ext } # namespace used for IMAP sharing feature namespace { type = shared separator = / prefix = shared/%%u/ location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u list = children subscriptions = no } -- Dovecot dict sql -------------------- # IMAP SHARING FEATURE connect = host=x.x.x.x dbname=xxxxxx user=xxxxxx password=xxxxxx map { pattern = shared/shared-boxes/user/$to/$from table = imap_user_shares value_field = dummy fields { from_user = $from to_user = $to } } map { pattern = shared/shared-boxes/anyone/$from table = imap_anyone_shares value_field = dummy fields { from_user = $from } } -- Dict DB contents -------------------- mysql> select * from imap_user_shares; +------------------------------------------+-------------------------------- --------+-------+ | from_user | to_user | dummy | +------------------------------------------+-------------------------------- --------+-------+ | test.imapsharer01(a)td01.testdomain.it | test.imapuser01(a)td01.testdomain.it | 1 | +------------------------------------------+-------------------------------- --------+-------+ For our tests, we've : - created two users test.imapsharer01(a)td01.testdomain.it test.imapuser01(a)td01.testdomain.it - Created two INBOX subfolders on the sharer01 user, giving user01 those permissions : subfolder01 giving to user01 Full control subfolder02ro giving to user01 list and read - logging as user01 with thunderbird, we see the shared namespace tree : shared test.imapsharer01(a)td01.testdomain.it subfolder01 subfolder02 we're able to see the contents of each folder, even the INBOX . Checking the folder properties, thunderbird reports that the user01 has full control on the INBOX of shared01 . If we try to check the ACL via python script ( imaplib.gestacl ) or via doveadm, we can see that the sharer01 INBOX has no rights for user01 . But via thunderbird ( or other email clients ) we can delete emails . ACL - sharer01 accessing its folder ('OK', [b'INBOX test.imapsharer01(a)td01.testdomain.it lrwstipekxacd']) ('OK', [b'subfolder01 test.imapuser01(a)td01.testdomain.it akxeilprwtscd test.imapsharer01(a)td01.testdomain.it lrwstipekxacd']) ('OK', [b'subfolder02ro test.imapuser01(a)td01.testdomain.it lr test.imapsharer01(a)td01.testdomain.it lrwstipekxacd']) ACL - user01 accessing sharer01 folders ('OK', [b'shared/test.imapsharer01(a)td01.testdomain.it/INBOX']) ('OK', [b'shared/test.imapsharer01(a)td01.testdomain.it/subfolder01 test.imapuser01(a)td01.testdomain.it akxeilprwtscd']) ('OK', [b'shared/test.imapsharer01(a)td01.testdomain.it/subfolder02ro test.imapuser01(a)td01.testdomain.it lr']) Testing with doveadm shows the correct ACL : #

Questions around mailcrypt and LDAP
by Andre Rodier 15 Nov '22

15 Nov '22

Hello, all. I read carefully the messages about mailcrypt on the mailing list, especially this response from Aki: > It's best suited for securing external storage such as NFS or object storage. > There are possibilities to encrypt the key using user's password, but this > takes careful planning. The keys can also come from userdb , e.g. LDAP. I am able to extend the LDAP schema of my OpenLDAP server to store a key into LDAP attribute for each user. In this case, would it be enough for Dovecot to encrypt the messages when they arrive ? Maybe I misunderstand the documentation. Even when using user keys protected by a password, the Dovecot LMTP process should be able to encrypt the emails with user’s public key, without a password, no ? Ideally, I would like to store user's emails encrypted, so each users cannot access other user's emails. I don't need folder sharing. Thanks for your advice. Kind regards, André Rodier

Dovecot not offering TLSv1.2 after a few minutes
by Markus Wienhöfer 14 Nov '22

14 Nov '22

I have a very strange problem with one of our Dovecot servers (2.2.33.2) on Ubuntu 18.04. The current configuration allows for TLSv1 to TLSv1.3 connections. I can verify those using testssl.sh, the tests will succeed (although correctly mentioning, that TLSv1 and TLSv1.1 should be disabled). Running the tests again after about 5 minutes, the results are different. TLSv1.2 now shows "not offered and downgraded to a weaker protocol". Has anybody experienced a similar problem before? Best regards Markus

Dovecot 2.3.19.1: BUG: Mailbox renaming algorithm got into a potentially infinite loop, aborting
by Ralf Becker 14 Nov '22

14 Nov '22

I found this from 2019 on the list: https://www.mail-archive.com/dovecot@dovecot.org/msg78898.html Timo mentioned it's tracked internally as DOP-1501, but I could find nothing about it being fixed on the (public) list. Any news about that and is the workaround of deleting dovecot.mailbox.log* and dovecot.list.index* still the recommendation, when running into this bug.

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>; Thu, 9 Nov 2022 08:27:41 +0000 So we've thought to use X-client, but reading the doc seems that's not the a good way : /https://doc.dovecot.org/settings/core// - submission_relay_trusted If enabled, the relay server is trusted. Determines whether we try to send (Postfix-specific) XCLIENT data to the relay server (only if enabled). But, XCLIENT for Submission seems to not transfer LOGIN : /https://doc.dovecot.org/settings/core/ / XCLIENT command can be used to override: Session ID Client IP and port (|%{rip}|,|%{rport}|) HELO - Overrides what the client sent earlier in the EHLO command LOGIN - Currently unused PROTO - Currently unused |forward_*| fields can be sent to auth process’s passdb lookup The trust is always checked against the connecting IP address. Except if HAProxy is used, then the original client IP address is used. Do you know another way to inform the relayhost of submission of the authenticated_user? Thanks Ismaël TANGUY

Help with configuration?

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 emails from the Debian mailing list to go into the 'Debian' folder. Can dovecot do this for me and what is the best approach? 2. When I delete an email using my user client, it is only 'marked' as deleted (Thunderbird places a scored line through it, and a 'T' is added to the filename in the Maildir). How can I get dovecot to automatically move mail marked 'deleted' to the Trash folder each time? I also want further delete operations on any mail in the 'Trash' folder to be permanently deleted. 3. I want to hide my client IP address from the headers when submitting mail to Dovecot's submissiond, but I can't seem to find any way to disable this. I would prefer that recipients only see the server IP address, but not the IP address of the mail client which submitted it. Regards, Ellie PS - When signing up for the mailing list, there was no selection ability on the question "Would you like to get replies to your mails only to the list, ie. add a Reply-To header?"
