v2.3.17 quota-dict related sql errors
by Pascal Volk 06 Feb '22

06 Feb '22

Hi there, I've updated Dovecot from v2.3.14 (cee3cbc0d) to v2.3.17 (e2aa53df5b). Right after the update, dovecot begun flooding the mail.log and PostgreSQL's log. My dict sql configuration: ,--[ .../dovecot/dovecot-dict-sql.conf.ext ]-- | map { | pattern = priv/quota/storage | table = userquota | username_field = uid | value_field = bytes | } | map { | pattern = priv/quota/messages | table = userquota | username_field = uid | value_field = messages | } `-- This worked for decades. Since the update dovecot is passing the user's email address, instead the user's UID to the query. And therefor I have lots of errors in the log files: see attached `mail.log' and `postgresql-14-main.log' excerpts. The `userquota' table looks like this: Table "public.userquota" Column | Type | Collation | Nullable | Default ----------+---------+-----------+----------+--------- uid | bigint | | not null | bytes | bigint | | not null | 0 messages | integer | | not null | 0 ... Foreign-key constraints: "fkey_userquota_uid_users" FOREIGN KEY (uid) REFERENCES users(uid) ON DELETE CASCADE (full database structure: https://bitbucket.org/pvo/vmm/src/vmm-0.7.0/pgsql/create_tables.pgsql) Regards, Pascal -- Ubuntu is an ancient African word meaning “I can’t install Debian.” -- unknown

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) 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. When I view the user's directory I see these folders were created: --- [snippet] drwxrwx---. 5 vmail vmail 135 Jan 25 17:01 .virtual.All/ drwxrwx---. 5 vmail vmail 158 Jan 25 17:14 .virtual.Flagged/ [.virtual.Flagged]# ll total 20 drwxrwx---. 5 vmail vmail 158 Jan 25 17:14 ./ drwxrwx---. 20 vmail vmail 4096 Jan 25 17:33 ../ drwxrwx---. 2 vmail vmail 6 Jan 25 16:58 cur/ -rw-rw----. 1 vmail vmail 868 Jan 25 16:58 dovecot.index.cache -rw-rw----. 1 vmail vmail 384 Jan 25 17:01 dovecot.index.log -rw-rw----. 1 vmail vmail 51 Jan 25 17:01 dovecot-uidlist -rw-r--r--. 1 vmail vmail 8 Jan 25 17:14 dovecot-virtual -rw-rw----. 1 vmail vmail 0 Jan 25 16:58 maildirfolder drwxrwx---. 2 vmail vmail 6 Jan 25 16:58 new/ drwxrwx---. 2 vmail vmail 6 Jan 25 16:58 tmp [.virtual.Flagged]# cat dovecot-virtual * flagged --- Side note: This set-up uses the php-imap library to interact with Dovecot.

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?

silly quesiton
by steph.mag220＠netcourrier.com 31 Jan '22

31 Jan '22

Hi, Up to now, I used PAM of each user in order to send and receive email. ( BTW, sending email, a use authentication was required and we used the login and passwd of the user on the system Now, for dovecot, I start to use MD5 passwrd.. and that sounds to be OK auth_mechanisms = plain login cram-md5 passdb { driver = passwd-file # Path for passwd-file. Also set the default password scheme. args = scheme=cram-md5 /etc/cram-md5.pwd } But changing the passwrd for the user1.. he can retrieve emails from dovecot, but cannot send anymore, because sending emails kept the old passwrd. ( using the PAM) 1) How can I says sendmail to use the same passwd file ( with MD5) than dovecot ? 2) Ideally, I would like to create virtual users for the same mailbox Is that possible ? like 2 files Users and PAsswrds pointing out the mailbox : maildir :/home/mailbox/user1 ex : user1(a)foo.com passwrd1 /home/mailbox/generic_mails and user2 passwrd2 home/mailbox/generic_mails How can I do that ? Thanks for your help

> 5. Re: can't authenticate (Christian Mack) hi Christian log with debugging resulting from a login attempt pasted at end - to try and make it more readable I removed everything in each line up to "dovecot:" At no point is a password revealed, even in hashed form. Should also say that the problem is identical on a backup laptop also running devuan 4; I'm not sure if I ever used that machine with dovecot before it was upgraded from devuan 3.

My openssl have shared libraries (libcrypto.so libssl.so ...) and the explicit use of CPPFLAGS and LDFLAGS to my openssl hasn't changed anything I use Openssl 3.0 but i've tested also 1.1.1m and 1.1.1g for example, same error! Dovecot is the latest 2.3.17.1 My OS is Ubuntu 21.04 Can anyone help me with this please? Thanks!
