When using dovecot container with sieve plugin there is no sendmail to use for sending email for sieve redirect action for example. We can use submission_host instead https://doc.dovecot.org/settings/core/#core_setting-submission_host but there is no way to specify credentials for auth in remote MTA. Submission_relay_* settings e.g. submission_relay_master_user relate to dovecot submission service. Using something like permit_mynetworks in remote MTA is not acceptable for security reasons. Is it possible to add authorization in the remote MTA using submission_host?

dovecot replication - new and cur folders on mx1 and mx2
by Tomaz Kavcic 18 Jan '23

18 Jan '23

Hello, I have a question in regards to specific dovecot replication behaviour and I'm just wondering if this is actually an expected/normal behaviour, or just a version issue. I'm using dovecot 2.3.16 which is packed by default with latest Ubuntu 22.04.1 LTS server release. I setup dovecot replication pair (mx1 - mx2) which is working ok. MX1 has priority 10, MX2 has priority 20. I use maildir (postfix + dovecot lmtp). The "strange" behaviour is this. When new mail arrives, it's by default delivered into "new" folder inside user directory. This email is then replicated to both servers (mx1 and mx2). When I login to mx1 via IMAP client (roundcube, outlook, etc.) that specific email is moved from "new" to "cur" folder on server mx1 and it's flagged also with "S", which probably means read flag. On server mx2, that email filename is also flagged with "S", but the email stays inside the "new" folder and it's not moved to "cur". If I want this email to be moved to "cur" on mx2 server, I have to login to that IMAP server as well, click on that email (which is already flagged as read), and after click, the email is also moved to "cur" on server mx2. Simply said, all new mails on mx1 server are moved to "cur" when accessed, but the stay in "new" folder on server mx2 until they're physically accessed there as well. Is this normal behaviour? I tried setup with TCP and SSH replication, and the situation is the same in all cases. Lastly, I tried TCPS (with SSL) as well, but that option has issues in 2.3.16, which is probably known already as I found multiple posts about these issues in this version. Thank you in advance for your answer and kind regards, Tomaz Kavcic. --- As suggested by mr. Timo Sarainen, this should be synced, so I'm posting doveconf -n as attachment for both servers as well.

Quota Clone Plugin
by MK 17 Jan '23

17 Jan '23

Hello Everybody, just a short question, maybe someone used this plugin and can give me a short answer. I have configured dovecot Quota Clone Plugin to copy quota information into a MySQL Database. Works finde, but dovecot writes the quota information only to the database if the quota is triggert by new email or something else like this. So I don't have all my user in the MySQL Database. Is there any command I can use that can trigger dovecot to write the quota information of all the users to the database one time, so that I have all my user quota information copied in the database? I have tried "doveadm quota recalc -A" but it took quite a long time and there is a very high I/O Load on the server, so I stopped it. I don't think this is what I want to do. Maybe there is another way. For all of you who don't know this plugin. https://doc.dovecot.org/configuration_manual/quota_clone_plugin/ Greetings, Oliver

hostname in director_mail_servers setting
by k v 16 Jan '23

16 Jan '23

director_mail_servers setting uses IP Adresses as values https://doc.dovecot.org/settings/core/#core_setting-director_mail_servers As described in the documentation, hostnames are converted to addresses when the configuration is read https://doc.dovecot.org/settings/types/#ip-addresses This is acceptable in host or virtual machine environment, but becomes a problem in a containerized environment. When any backend container is restarted, its address will change and users related to this backend can no longer connect, but backend (available with new IP address) can process request for example, director_mail_servers = dovecot-1 dovecot-2 dovecot-3 becomes in runtime (with one successfully connectetd user foo(a)example.com) doveadm director status mail server ip tag vhosts state state changed users 10.0.71.3 100 up - 0 10.0.71.4 100 up - 1 10.0.71.5 100 up - 0 where dovecot-1 10.0.71.3, dovecot-2 10.0.71.4, dovecot-3 10.0.71.5 When dovevecot-2 backend container restarts, and becomes new IP address, user can't connect to related backend: imap-login: Info: proxy(foo@example.com,10.0.71.4:143): Started proxying to <10.0.71.4> (<dovecot-2>) (0.009 secs) imap-login: Error: proxy(foo@example.com,10.0.71.4:143): connect(10.0.71.4, 143) failed: No route to host (after 28 secs, 3 reconnects, local=10.0.71.13:41066) My suggestion to developers: resolve backend hostnames to IP address on every request to director_mail_servers It's not about dovemon service with active health checks from dovecot pro, just dynamic hostname resolve

Error: Mailbox INBOX: file_dotlock_create in directory /var/mail failed: Permission denied
by manmatha 16 Jan '23

Hi All, We are running Round cube on top of dovecot and postfix as our email echo system. Main problem we are facing is that, roundcube loads really slow for big inboxes (~5000 emails). I found that, while it loads, imap process goes high in terms of CPU utilization(~90%). I asked it in some roundcube support group, They believe that it is related to dovecot not roundcube. Can you shed any light on this issue. Thanks in advance.

Up to date dovecot packages on Ubuntu 22.4LTS
by Gerben Wierda 12 Jan '23

12 Jan '23

I just found out that Ubuntu Linux 22.04 LTS has a dovecot apt package that is 2.3.16. Debian 11 (stable) is at dovecot 2.3.13 with apt. if I looked correctly. Dovecot itself is at 2.3.20. That surprised me (I am new to the Linux distro and package management world) as Ubuntu 22.04 is a Long-Time Support version, and I was expecting packages to be updated as well (as many users will want updated packages. How does that work in the dovecot world? How come macOS MacPorts (2.3.19) has more recent packages than any of the large Debian-based Linuxes?

director: pass different username to proxy than the one that is used for hashing
by alex 12 Jan '23

12 Jan '23

dovecot 2.3.13 Hi, I'm looking for a way to make director use a user@domain that is returned by the database for hashing but actually send the original user@domain in the proxied request. I cannot seem to find a way. I can change the name used for hashing by just returning a different user from the db. but that user is also the one that is send in the proxied request. this is what I have so far: director_username_hash = %L{user} # relevant sql: password_query = SELECT \ username as user, \ # -> this is used for hashing if destuser is not present. = OK NULL as password, \ 'y' as proxy, \ 'y' as nopassword, \ '%n@%d' as destuser \ # -> but as soon as I add this, this is used for hashing = !OK FROM dovecot_data('%n', '%d') Anyone know any clever tricks to accomplish this? Thanks! Alex (background: I've inherited a mail setup where mailboxes have multiple logins. (those all share the same 'home' for their maildirs). I need all of these to go to the same server. Most ideal would be hashing on home '%h' instead of %u :)).

Living without fdpass / SCM_RIGHTS
by Dengler, Gabriel 10 Jan '23

10 Jan '23

Hello everyone, I wanted to run Dovecot inside Gramine [1]. Gramine is a tool to let normal Linux binaries run with the help of the Intel Software Guard Extensions (SGX) technology [2] in a secure enclave to which the operating system doesn't have an access to. Most parts of Dovecot now run fine, however, Dovecot uses the SCM_RIGHTS flag for the sendmsg system call to exchange file descriptors over Unix sockets [3]. Normally, this feature is available in every Unix, but in Gramine, this is currently not supported [4]. So, according to the logs, the authentication works, but after that, the imap-login process cannot exchange the file descriptor with the imap process. Therefore I wanted to ask if there is a possibility to make Dovecot work without this feature or if this would need fundamental changes in the code structure. Thanks for your help in advance! Best regards, Gabriel References: [1] https://gramineproject.io/ [2] https://de.wikipedia.org/wiki/Software_Guard_Extensions [3] https://github.com/dovecot/core/blob/main/src/lib/fdpass.c#L128 [4] https://github.com/gramineproject/gramine/discussions/1013#discussioncommen…

Dovecot - mail_crypt - lmtp-server - no password to decrypt the key
by Baljeet Bhinder 09 Jan '23

09 Jan '23

I have been using postfix+dovecot successfully for a while now until I tried mail crypt plugin lately. I tried what is describe here https://doc.dovecot.org/configuration_manual/mail_crypt_plugin/ and I went for global-keys as described here: https://doc.dovecot.org/configuration_manual/mail_crypt_plugin/#global-keys /"A good solution for environments where no user folder sharing is needed is to generate per-user EC key pair and encrypt that with something derived from user’s password."/ I am setting mail_crypt_global_private_key, mail_crypt_global_public_key, mail_crypt_save_version from user_query and userdb_mail_crypt_global_private_key_password from password_query. mail_crypt seems to work fine in imap (I saved a message as draft and it is stored encrypted on the disk), but lmtp complains about "mail_crypt_global_private_key_password unset, no password to decrypt the key" As you can see below in logs that it was able to set all other mail_crypt_ configurations successfully from user_query. However, the password is provided via password_query and I assume lmtp does not read password_query. How else can I provide a password in lmtp? Is my approach correct to begin with? -- Dovecot Configurations -- # using doveconf -n # 2.3.19.1 (9b53102964): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.19 (4eae2f79) # OS: Linux
