Ubuntu Version: Linux 6.2.0-1017-aws x86_64 Ubuntu 22.04.4 LTS nfs4 Postfix: Version: 3.6.4 Dovecot Version: 2.3.16 (7e2e900c1a) Pigeonhole Version: 0.5.16 (09c29328) Rspamd Version: 3.8.4 Protocols: IMAP, LMTP, SMTP Setup: I have an email server running with virtual domains and virtual mailboxes that is currently hosting about 10GB of email across 15 domains and 8 mailboxes which will expand drastically once I get this to work. The server is an AWS EC2 instance with an AWS RDS instance for the database and using AWS EFS for storage. Everything works quite well except quotas! Problem: I am having an issue with getting quotas to work. When using “doveadm”, I can list the mailboxes however the “Limit” column is just a hyphen “-“ like there is no limit even though every account is set to 10GB for their limit in the database. At the same time, the actual used storage and messages is not getting updated in the database either yet there are no errors from what I can see in the logging.

What I am expecting us when emails are delivered for the “quota” and “messages” columns in the “mailbox” table to be updated and when I run “doveadm quota get -A” to show me the current usages and limits for each mailbox. Once I have that working, I will move on to actually rejecting emails via Postfix + Dovecot LMTP when a users mailbox is full but right now, I am just trying to get this to work. Any help is greatly appreciated. Also, I tried creating an account for the mailing list but never received the email. Thank you!

Gather statistics to check effectivity of spam filter?
by Camilo Sperberg 30 May '24

30 May '24

Hi list :) We want to make some changes to our spam filter, but we first want to be able to check if what we do does have any effect. So I was thinking of storing in our statistics if somebody moves an email to their Junk folder (or even better: vice versa). I have created the following metric for this: metric imap_command_move { filter = event=imap_command_finished AND cmd_name="UID MOVE" AND (cmd_args = "* Junk" OR cmd_args = "* INBOX") group_by = cmd_args } And when I move something to the Junk folder I get the following after a doveadm stats dump: (...) imap_command_move duration 5 252529 27061 124989 50505.80 34476 37503.81 124989 imap_command_move_15_Junk duration 1 124989 124989 124989 124989.00 124989 0.00 124989 imap_command_move_14_Junk duration 1 38725 38725 38725 38725.00 38725 0.00 38725 imap_command_move_12_INBOX duration 1 27061 27061 27061 27061.00 27061 0.00 27061 imap_command_move_13_INBOX duration 1 27278 27278 27278 27278.00 27278 0.00 27278 imap_command_move_3_INBOX duration 1 34476 34476 34476 34476.00 34476 0.00 34476 In my example, I moved 6 messages: 2 from INBOX to Junk, 1 from INBOX to a separate folder, 2 from Junk back to INBOX and 1 from the separate folder back to INBOX. However, because I'm grouping by cmd_args, it includes the full parameters: IMAP command’s full parameters (e.g. 1:* FLAGS) https://doc.dovecot.org/admin_manual/list_of_events/#imap-command Is there a way to filter out the first part so that I ideally get a stat named imap_command_move_Junk & imap_command_move_INBOX? Is there perhaps a way to get to know specifically the from and to folders the user is moving the mail from and to? Thanks!

Oauth2 MFA config
by Scott Q. 24 May '24

24 May '24

Anyone managed to get Dovecot working as smoothly with OAUTH2 as Gmail has with Outlook ? So that for example when you add the account up in Outlook it performs all the required steps for saving the device, getting tokens, etc. Ideally with a custom ID provider, not Google as described here: https://doc.dovecot.org/configuration_manual/authentication/oauth2/

I can't configure shared mailbox ACLs using LDAP information
by moso.mosoleu＠gmail.com 24 May '24

24 May '24

It shouldn't be impossible, but I've tried countless ways and not even ChatGPT 4o was able to help me! :D I use three LDIF files to get OpenLDAP ready for testing. In the first LDIF I just modify the schema to add the associatedDomain attributes (then I could configure the server to serve more than one domain). The second LDIF is to add 4 objects to the schema that I use to differentiate accounts that actually receive/send emails and have a password; another thing done in it is to add a "groupOfUniqueNamesWithMail" object that allows the "mail" and "mailEnabled" attributes that are then necessary to use in the entries created in the "shared-mailboxes" OU. Finally, the third LDIF populates the LDAP by creating OUs, user accounts and creating entries in "shared-mailboxes" that serve to say which user accounts have access to which other user accounts. When I start the email server, sending and receiving emails works perfectly. And mailbox shares work as expected if I manually use, for each share, the command: doveadm acl set -u admin(a)mydomain.com.br INBOX user=user.1(a)mydomain.com.br lookup read write write-seen write-deleted insert post expunge create delete But just as authentication works perfectly via LDAP, I believe there must be a way to configure Dovecot to dynamically adjust ACLs via LDAP. The configuration in principle would be this: acl_search_base = ou=shared-mailboxes,dc=mydomain,dc=com,dc=br acl_search_filter = (&(objectClass=groupOfUniqueNamesWithMail)(|(uniqueMember=mail=%u,ou=system-accounts,dc=mydomain,dc=com,dc=br)(uniqueMember=mail=%u,ou=department-accounts ,dc=mydomain,dc=com,dc=br)(uniqueMember=mail=%u,ou=mailing-accounts,dc=mydomain,dc=com,dc=br)(uniqueMember=mail=%u,ou=person -accounts,dc=mydomain,dc=com,dc=br))) acl_user = %u Testing this filter on the command line with "ldapsearch" the expected results are returned. I mean, I enter an email address from a user account and the result is all the other user account email addresses that the first one would have access to. Any charitable soul who is willing to help and needs more information, just say what you need and I will try to respond as quickly as possible. I will place the content of the three LDIFs below.

Command "doveadm director kick ...." doesn't work
by g.carabella＠panservice.it 23 May '24

23 May '24

Hi, I have a Dovecot installation (version 2.3.16) with 3 directors and 4 backend servers. Three backend servers have the director_tag 'new', one has the director_tag 'old'. The users are on the DB, the director_tag is a table field. I want to migrate mailboxes from the old backend (Maildir format) to the new (mdbox format). For the migration I use the "doveadm backup" command and everything works fine. The problem I'm having is that I can't kick the user (if logged in). Once the migration is done (as indicated https://doc.dovecot.org/3.0/man/doveadm-sync.1/) I modify the user's home, mail_location and director_tag and then execute the command "doveadm director kick ..." but the connection on the directors is not killed. Why does this problem occur? Could it be due to the use of the director_tag and the fact that for the command "doveadm director kick ..." it is not possible to specify it? Even if I run the command "doveadm director move mailbox_account new_backend_server", the director adds a new connection but does not kill the previous one, with the result that there are two connections for the same user, one on the new backend and one on the old one. I also tried to configure the director_tag only for the 3 new servers, but the "director kick" still doesn't work.

Problems using non-libc memory allocators
by bl0v3 22 May '24

22 May '24

Hey I was trying to use dovecot2 with a not libc based memory allocation such as scudo or graphene-hardened or graphene-hardened-light but ran into the issues I described in https://github.com/NixOS/nixpkgs/issues/313721 I just wanted to mention this here as well as this behavior may suggest a flaw in the memory allocation mechanism of dovecot2/anvil. I haven't yet found the time to check the underlaying issue as I'm quite busy rn. So I thought id just mention what I came across in case this is actually unexpected or potentially even security relevant mis/behavior.

Dovecot calculating quota wrong or am I stupid?
by jarland＠mxroute.com 21 May '24

21 May '24

I'm currently running 2.3.21 on this system and here's what I'm seeing (a bit cut down for excess): # doveadm quota get -u emailuser(a)domain.net STORAGE 1052385 MESSAGE 2741 So the storage is roughly more than 1GB according to Dovecot. No change after quota recalc. But: root@arrow:/home/username/imap/domain.net# du -sh emailuser 692M emailuser There are no symlinks or anything like that. Quota config is pretty basic: root@arrow:/etc/dovecot# cat conf.d/90-quota.conf #add quota to end of line in: #/etc/dovecot/conf/mail_plugins.conf, eg: #mail_plugins = $mail_plugins quota #add imap_quota to end of line in: #/etc/dovecot/conf/imap_mail_plugins.conf, eg: #mail_plugins = $mail_plugins imap_quota plugin { quota = maildir } If anyone has advice I would greatly appreciate it.

See https://doc.dovecot.org/admin_manual/list_of_events/#mail-user-session-fini… You will need to build a event listener for this event, and then do your scripting in there. michael

After user disconnect run the custom script
by Alexey Krylov 20 May '24

Sirs, good day. Please, send me the link, where I can find the info about configuring firing script after dovecot client is disconnected. I found post-login scripting. Than's cool, but... I need to fire script a little bit later. May be I try to build crutches... But I wish with all my heart to do this.
