I am getting errors addressing environment variables. Are they supposed to work in such sections. Not really clear from this[1] page. service health-check { # example health-check. executable = script -p /bin/health-check.sh inet_listener health-check { port = env:PORT0 } } [1] https://doc.dovecot.org/configuration_manual/config_file/config_variables/

Strange index error on NFS after upgrade to CentOS 7 from 6
by Alessio Cecchi 25 Aug '20

25 Aug '20

Hi, I'm running 3 Dovecot director and 6 Dovecot backend on CentOS 6 and Dovecot 2.3.10, with Maildir shared on NFSv3 (on NetApp). Since CentOS 6 will be EOL on November I started to upgrade to CentOS 7 the first Dovecot backend. But after Director start to direct users on new CentOS 7 server some errors, for any users, come up, an example: Aug 21 14:56:41 Error: imap(alessio(a)cecchi.it) session=<11sBlmKtj1qelGW/>: Mailbox INBOX: Broken or unexpectedly changed file /home/vmail/domains/cecchi.it/alessio/Maildir/dovecot-uidlist line 18664: Invalid data: - re-reading from beginning Aug 21 14:56:41 Error: imap(alessio(a)cecchi.it) session=<11sBlmKtj1qelGW/>: Mailbox INBOX: Broken file /home/vmail/domains/cecchi.it/alessio/Maildir/dovecot-uidlist line 18664: Invalid data: Consequently to the error the user see the synchronization of his mailbox again. The Dovecot version and configuration is the same that in CentOS 6, also the mount parameters are the same, so I suspect that could be some difference in the NFS client implementation on CentOS 7. This the entry on fstab: 192.168.1.2:/vmail0 /mnt/vmail0 nfs rw,nfsvers=3,noatime,nodiratime,_netdev,nordirplus 0 0 # Bind for vmail0 /mnt/vmail0/domains /home/vmail/domains none x-systemd.requires=/mnt/vmail0,x-systemd.automount,bind 0 0 In the archive of this list I found a similar issue but without a solutions: https://dovecot.org/pipermail/dovecot/2018-October/113207.html Do you have any suggestions?

doveadm/doveconf as user tries and fails to read host key
by jimc 25 Aug '20

25 Aug '20

Distro: OpenSuSE Tumbleweed for x86_64 Failing version: dovecot23-2.3.11.3-1.1.x86_64 Install Date: 2020-08-18 Reverting to previous version works: dovecot23-2.3.10.1-2.3.x86_64 (Packages downgraded coordinately: dovecot23 dovecot23-backend-sqlite) How to make it fail: As the user, execute doveadm expunge mailbox Spam37 savedbefore 3day #User's actual cmd doveadm who #The simplest possible command, for testing It says: doveconf: Fatal: Error in configuration file /etc/dovecot/conf.d/10-ssl.conf line 12: ssl_cert: Can't open file /etc/ssl/hostcerts/hostw.cia: Permission denied The actual EPERM occurs trying to traverse a directory in /etc/letsencrypt, but the next configuration item to be read (in the SSL section) is the host's private key, and the user is surely not ever going to get permission to read that. (I did test giving the user permission to the 750 directory and it did attempt to read the private key, failing.) If you run it as root, of course it works because root has read permission. The initial failure was seen running as the user from cron. Behavior seen in strace: doveadm execs doveconf; doveconf reads the configuration and saves it somewhere (shared memory?); doveconf execs the next program which in this case is doveadm with its original command line; and doveadm now knows its configuration. I can re-do and post the strace if needed. I don't know why doveconf is reading the SSL keys in 2.3.11.3 when it didn't in 2.3.10.1, but if the idea is to read the complete configuration in case it might be needed in obscure situations, a possible workaround is to not die on unreadable secrets and to report those either as unset or as a new "error" symbol, letting the consumer (doveadm) deal with the fallout, or in this case ignore it.

RHEL7/CentOS7 RPM of dovecot 2.3.11.3-3 seems to have dropped tcpwrap support
by Thomas Scheunemann 22 Aug '20

22 Aug '20

Using the Repo http://repo.dovecot.org/ce-2.3-latest after upgrading from 2.3.10.1-3 to 2.3.11.3-3 we get numerous error messages like: dovecot: imap-login: Error: connect(tcpwrap) failed: No such file or directory We use tcpwrap support in dovecot, which worked flawlessly in the older version. I can see that the socket /var/run/dovecot/login/tcpwrap is not created anymore. And comparing with RPMs, the new one seems to be missing the file: /usr/libexec/dovecot/tcpwrap which leads me to conclusion that the new version is just not compiled with tcpwrap support.

dovecot-SASL for Postfix: EXTERNAL does not work.
by Steffen Nurpmeso 21 Aug '20

21 Aug '20

Hello. I am not subscribed and new here, so first of all i want to thank you for dovecot. I personally do not use it in "production" (yet), but it is my sole point of interaction for testing the little MUA i maintain for quite some years. I also have used its code for affirmation purposes. (Interesting that OAUTHBEARER treats hostname and port as optional. I currently do OAUTHBEARER.) So then i stumbled over GSSAPI not being usable anymore with the latest release, but it seems there is an ML thread with a fix. I have not tried it, i reverted to the last release here, though. When i implemented EXTERNAL authentication last year i could not figure out how to make postfix+dovecot-SASL work with it. First of all i had to switch configs back and forth, but in the meantime i learned a very nice trick: if i use two password databases passdb { driver = passwd-file mechanisms = external args = /etc/dovecot/pass-external.db override_fields = nopassword } passdb { driver = passwd-file args = /etc/dovecot/pass.db } userdb { driver = passwd } which are effectively the same except that one does not have passwords while the other has, i can use EXTERNAL (with and without additional user-via-protocol in combination with auth_ssl_username_from_cert=yes and it just works! Whereas EXTERNAL works just fine for IMAP and POP3 it does not for SMTP. Last year when i did it i saw a postfix ML thread in action, so i have not looked further into that. Looking again with things unchanged in the postfix 3.5 that they mentioned by then i think, i now posted to the postfix list myself yesterday [1], and it turned out that postfix seems incapable to do something about it, because the dovecot auth protocol does not offer the possibility to specify a valid-user-certificate-seen flag as well as pass the username from the certificate. (Or even pass the entire certificate as a base64 string, less postfix CA, .. or whatever.) [1] https://marc.info/?l=postfix-users&m=159785887710910&w=2 What is really terrible with the current situation is that postfix announces the EXTERNAL, with Wietse Venema saying Short summary: Postfix does not implement a single iota of SASL AUTH support. Postfix simply propagates the names of mechanisms that the backend (Cyrus or Dovecot) claims to support, and Postfix proxies requests and responses between the remote SMTP client and the SASL backend. Postfix has no idea what SASL mechanisms are, including EXTERNAL. It just proxies stuff. If Dovecot claims to support SASL EXTERNAL but does not handle it, that that is a bit of a WTF. It would be tremendous to have true EXTERNAL support all through, i personally really like EXTERNAL, i would rather have some password-protected crytographically secured certificates in my local store, and have client certificates in all the IoT devices, than have to mess around with the OAUTH that the major players press forward, for example.

Adjusting logging with the "remote" syntax
by Jason Young 21 Aug '20

21 Aug '20

According to the docs, we can use ‘local’ and ‘remote’ blocks to change configuration directives. In my current setup (Mail-in-a-box using Nextcloud, which is configured for IMAP authentication), my mail logs are spammed with local logins. I really don't need these reports, but still want to retain login logs for remote IPs. So I set the following in my configuration: remote 127.0.0.1 { info_log_path = /dev/null } When I run "doveadm -n -f remote=127.0.0.1”, it does seem to understand it: --- # 2.2.33.2 (d6601f4ec): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.21 (92477967) ... info_log_path = /dev/null ... remote 127.0.0.1 { info_log_path = /dev/null } --- However, I’m still getting spammed with local login reports: Aug 12 12:17:13 imap-login: Info: Login: user=<user(a)domain.tld>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=29798, TLS, session=<FGVJhbCsstt/AAAB> Aug 12 12:17:13 imap(user(a)domain.tld): Info: Logged out in=305 out=2277 I've also tried logging to a specific file, instead of /dev/null, but no file was created. So there must be an issue with my understanding. How can I prevent logins from localhost from being logged without sacrificing logs for all logins? -Jason Young

OT: SASL questions
by Richard Hector 21 Aug '20

21 Aug '20

Hi all, Apologies for the somewhat off-topic questions - I'm trying to get my head around SASL, and what it is/does. I can see that a (SMTP, IMAP etc) server can offer various authentication methods, which are pre-defined and which the client can choose from. SASL then seems to define how those work. But dovecot and cyrus-sasl both seem to offer a client-server interface, usable by eg postfix, which I don't see any reference to in SASL summaries online. Is that a standard interface? ie can a client like postfix talk to either dovecot or cyrus without knowing the difference? Are there others? Is there a good reference to this somewhere, short of reading the RFCs? And is there any option (current or proposed) to let dovecot act as a client, rather than a server? Thanks, Richard

Rootless wiki page is not up to date?

If I run a docker image with the mesos containerizer and altering the dovecot config mentioned here[1] I think the root detection is incorrect because it looks like dovecot is still thinking it is root. I still get errors like: >> log(829825): Fatal: We couldn't drop root group privileges (wanted=10053(dovecot), gid=0(root), egid=0(root)) Why does it want to drop to root, if we are not even running as root? >> Error: service(ipc): chown(/var/dovecot/login/ipc-proxy, 91, 4294967295) failed: Operation not permitted Why does it want to chown, when it is not root? pop3-login: Fatal: setgid(101(dovenull)) failed with euid=10053(dovecot), gid=10053(dovecot), egid=10053(dovecot): Operation not permitted (This binary should probably be called with process group set to 101(dovenull) instead of 10053(dovecot)) [1] https://wiki.dovecot.org/HowTo/Rootless?action=edit&editor=text

User bar(a)example.de has shared a few mailboxes: # doveadm acl get -u bar(a)example.de INBOX ID Global Rights user=foo(a)example.de lookup read write-seen # doveadm acl get -u bar(a)example.de Sent ID Global Rights user=foo(a)example.de lookup read write-seen # doveadm acl get -u bar(a)example.de Drafts ID Global Rights user=foo(a)example.de lookup read write-seen But user foo(a)example.de can't see the shared INBOX: # doveadm mailbox list -u foo(a)example.de Trash Sent Drafts Junk shared shared/bar(a)example.de shared/bar(a)example.de/Sent shared/bar(a)example.de/Drafts INBOX A review of the ACL does not explain the behaviour: # doveadm acl debug -u foo(a)example.de shared/bar(a)example.de/INBOX doveadm(foo(a)example.de): Info: Mailbox 'INBOX' is in namespace 'shared/bar(a)example.de/' doveadm(foo(a)example.de): Info: Mailbox path: /srv/mail-storage/mailhome/example.de/bar/Maildir doveadm(foo(a)example.de): Info: Per-user private flags in mailbox: \Seen doveadm(foo(a)example.de): Info: User foo(a)example.de has rights: lookup read write-seen doveadm(foo(a)example.de): Info: Mailbox found from dovecot-acl-list doveadm(foo(a)example.de): Info: User bar(a)example.de found from ACL shared dict doveadm(foo(a)example.de): Info: Mailbox shared/bar(a)example.de/INBOX is visible in LIST ---------- doveconf -n ---------- # 2.3.4.1 (f79e8e7e4): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.4 () # OS: Linux 4.19.0-10-amd64 x86_64 Debian 10.5 # Hostname: XXX.YYYY.de auth_master_user_separator = * auth_verbose = yes first_valid_gid = 401 first_valid_uid = 401 last_valid_gid = 401 last_valid_uid = 401 mail_gid = vmail mail_home = /srv/mail-storage/mailhome/%d/%n mail_location = maildir:~/Maildir mail_plugins = " acl listescape zlib" mail_uid = vmail 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 inbox { inbox = yes location = mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Junk { auto = create special_use = \Junk } mailbox Sent { auto = subscribe special_use = \Sent } mailbox "Sent Messages" { auto = no special_use = \Sent } mailbox Trash { auto = subscribe special_use = \Trash } prefix = separator = / type = private } namespace shared { list = children location = maildir:/srv/mail-storage/mailhome/%%d/%%n/Maildir:INDEXPVT=~/Maildir/shared/%%d/%%n prefix = shared/%%u/ separator = / subscriptions = yes type = shared } passdb { args = /etc/dovecot/master-users driver = passwd-file master = yes pass = yes } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { acl = vfile acl_shared_dict = file:/srv/mail-storage/mailhome/shared-mailboxes.db sieve = file:~/sieve;active=~/.dovecot.sieve zlib_save = gz zlib_save_level = 6 } protocols = " imap lmtp sieve" service auth { unix_listener auth-userdb { mode = 0777 } } ssl = required ssl_cert = </var/lib/dehydrated/certs/XXX.YYYY.de/fullchain.pem ssl_dh = # hidden, use -P to show it ssl_key = # hidden, use -P to show it userdb { driver = static } userdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } protocol lmtp { mail_plugins = " acl listescape zlib sieve" } protocol imap { mail_max_userip_connections = 20 mail_plugins = " acl listescape zlib imap_acl" } ------------------------------ I don't think it is relevant, but I don't want to forget to mention that /srv/mail-storage/ is an NFS share. It would bee nice if someone has a hint. I hope it isn't a bug. Regards Torsten

pop3_migration plugin
by Andrea Gabellini 19 Aug '20

19 Aug '20

Hello, I'm trying to migrate from an old courier-IMAP server on which I made a plugin to access the individual mailboxes with a master password Emails are used in both POP3 and IMAP. I followed this guide https://wiki.dovecot.org/Migration/Dsync In the log I find these messages, which are generated by the server independently without issuing the command "doveadm backup ..." dsync-local (xxxxxxx) <yIAgHZtVPF85HwAA9osHUQ>: Error: pop3_migration: 8044 POP3 messages have no matching IMAP messages (first POP3 msg 1 UIDL UID33550-1353000352) - all IMAP messages were found (POP3 may contain more than IMAP to INBOX - you may want set pop3_migration_all_mailboxes = yes) - set pop3_migration_ignore_missing_uidls = yes or pop3_migration_ignore_extra_uidls = yes to continue anyway The mailboxes obviously have at least the "Sent", "Trash" and "Drafts" mailboxes. What should I do? Where can I find documentation of the pop3_migration plugin?

Sieve scripts replication not working

Hi all! I am a long-time dovecot user/admin on my home server, but only recently tried to configure replication. Everything seems to work except sieve scripts replication. When I upload new one on the server A, it does not replicate to server B, even if it seemingly tries to, according to debug logs. The log antry says: Replication requested by 'sieve_storage_sync_transaction_begin', priority=1 on server A, but nothing like that on server B. Server B logs show that server A is connecting to doveadm service but little else. Any ideas what could be wrong? Please see the logs below.

For now I'm going ot have to bypass the make check stage of the build for CentOS 6, but I worry that the failed check could be indicative of something critical. Peter

|Dear all,| |a couple of days ago I upgraded our server from Ubuntu 18.04 to 20.04, thereby upgrading dovecot from 2.2.x to 2.3.x. | |Since then, some older versions of apple's mail.app (bundled with el Capitano, released in 2016) no longer connect. When I turn on SSL debugging, I see:| |Debug: SSL error: SSL_accept() failed: error:14209102:SSL routines:tls_early_post_process_client_hello:unsupported protocol imap-login: Debug: SSL error: SSL_accept() syscall failed: Invalid argument| || |Unfortunately, it doesn't reveal the name of the unsupported protocol. Also, what about the failed syscall? Does dovecot try and fail to open some file?| |Here are the contents of /etc/dovecot/conf.d/10-ssl.conf:| | ssl = yes ssl_cert = </etc/ssl/letsencrypt/idaweb-mail.rooot.de/fullchain.pem ssl_key = </etc/ssl/letsencrypt/idaweb-mail.rooot.de/key.pem ssl_ca = </etc/ssl/letsencrypt/idaweb-mail.rooot.de/ca.pem ssl_client_ca_dir = /etc/ssl/certs ssl_dh = </etc/dovecot/dh.pem | |I would greatly appreciate any hints! | |Cheers,| |Johannes | | | ||
