/usr/libexec/dovecot/anvil crashes immediately

Dear list, I built a dovecot package for openindiana (which is a Solaris derivative) from latest version 2.3.18. Everything compiles and builds fine without any issue. Even subsequent installation and startup of main dovecot process works as expected. But execution of /usr/libexec/dovecot/anvil immediately crashes. To get some more meaningful backtrace I compiled with -g. Below some facts of my environment and a backtrace. Maybe some of you are more familiar with this kind of issue as I, and can give some hint or share ideas how to nail down the problem. Or can it be a configuration issue? BTW it is running in a so-called zone. And former versions, I don't know exactly but I believe up to 2.3.17, did not show this crash. gcc --version gcc (OpenIndiana 7.5.0-il-0) 7.5.0 Configure parameters: gcc_OPT = -g CONFIGURE_OPTIONS+=

Index Corruption Problem with new VM Host - But Only With Replication Enabled
by Reuben Farrelly 21 Feb '22

21 Feb '22

Hi, I've recently migrated my two VMs across from Linode (who use KVM) onto a local VPS service (which also uses KVM). Since doing so I have started to see some strange problems with Dovecot relating to indexes and replication. I have copied the configuration files across from old host to new host. The kernel is the same - as this is Gentoo everything was rebuilt and installed from fresh, but with the same options (use flags). Even the Linux kernel is the same version with the exact same options (as is Dovecot). The filesystem is the same EXT4 with the same options too. Here is what is logged: Feb 18 15:20:41 tornado.reub.net dovecot: imap(reuben)<20031><d0yxIEPY3ROfxG3u>: Error: Mailbox INBOX: /home/reuben/Maildir/dovecot.index reset, view is now inconsistent Feb 18 15:20:41 tornado.reub.net dovecot: imap(reuben)<20031><d0yxIEPY3ROfxG3u>: Disconnected: IMAP session state is inconsistent, please relogin. in=146 out=1398 deleted=0 expunged=0 trashed=0 hdr_count=0 hdr_bytes=0 body_count=0 body_bytes=0 The trigger is the move/delete of an email. Just reading seems to be OK. But as soon as you move/delete an email this event occurs and is logged. The move fails on the first attempt (error is logged, client refreshes) but then if attempted again it succeeds. This error causes the clients to be thrown off and the client view refreshed which seems to require a redownload of everything. It is extremely disruptive to client access. The odd thing is that as soon as I disable replication by commenting out the mail_replica line, *all* of the index corruption messages and symptoms go away completely and I don't see this problem occur. As soon as I re-add it they come back. So it appears that replication at least is triggering the problem. Replication is imap1 -> imap2 and on the other host imap2 - imap1 The odd thing is that this never was a problem while the system was on Linode. I have removed all files on the remote and let dovecot re-replicate everything but this didn't help. I can go back to the VPS host and talk to them about it as I have an open ticket but from their perspective it looks like an application level problem, so there's not a lot for them to go on especially given everything else is working OK. Could the underlying host be playing a role in this? It seems unlikely given turning replication or or off causes the problem to appear or disappear. All clients are connecting to only the master of the two replication partners. Many have multiple concurrent sessions (eg my phone, and Thunderbird at the same time) but all are connecting to only one instance at a time. The second instance is only there for a failover scenario (update a DNS entry to failover). There is no NFS or any sort of sharing set up on the VMs. They are dedicated virtual disks. Can anyone give me any ideas how to troubleshoot this further or things to try?

initial replication or clone?
by Joachim Lindenberg 19 Feb '22

19 Feb '22

Hello, I want to improve availability of my dovecot installation by implementing replication as outlined in https://wiki.dovecot.org/Replication. I am wondering whether I have to install an empty copy or whether it is also an option to clone the entire existing system and then configure replication, just to avoid the initial overhead. Any input? Thanks, Joachim

Hello, With Dovecot 2.3.18 on AlmaLinux 8 I’m trying this: LIBEXTTEXTCAT_LIBS="-L/usr/lib64 -lexttextcat" ./configure --with-textcat … which gives me: checking for special_textcat_Init in -lexttextcat... no checking for special_textcat_Init in -ltextcat... no configure: error: Can't build with textcat support: libtextcat or libexttextcat not found I do have: > ls -la /usr/lib64 | grep textcat lrwxrwxrwx 1 root root 26 Oct 12 2019 libexttextcat-2.0.so.0 -> libexttextcat-2.0.so.0.0.0 -rwxr-xr-x 1 root root 22128 Oct 12 2019 libexttextcat-2.0.so.0.0.0 Is there some way of knowing what command it’s actually running that makes it say “libtextcat or libexttextcat not found”? Thank you! cheers, -Felipe Gasper

Debug shared namespace issues

Hi Team, I am still having troubles with the shared namespace. mail_shared_explicit_inbox = yes namespace { type = shared separator = "~" prefix = shared~%%u~ location = maildir:/srv/mail/vmail/example.com/%%n/store:LAYOUT=fs:FULLDIRNAME=0_Folde… hidden = no list = children subscriptions = no } To rule out ACL issues (for now), I have added: plugin { acl = vfile acl_shared_dict = file:/srv/mail/dovecot/lib/shared-mailboxes.db #acl_defaults_from_inbox = yes acl_user = %n acl_ignore_namespace = shared~ } The client imap communication looks like this: C[0x55ae80480750]: 1 login "test2" "" S[0x55ae8044a600]: 1 OK [CAPABILITY IMAP4rev1 SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS THREAD=ORDEREDSUBJECT MULTIAPPEND URL-PARTIAL CATENATE UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS BINARY MOVE SNIPPET=FUZZY PREVIEW=FUZZY STATUS=SIZE SAVEDATE LITERAL+ NOTIFY SPECIAL-USE ACL RIGHTS=texk] Logged in C[0x55ae80480750]: 2 capability S[0x55ae8044a600]: * CAPABILITY IMAP4rev1 SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS THREAD=ORDEREDSUBJECT MULTIAPPEND URL-PARTIAL CATENATE UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS BINARY MOVE SNIPPET=FUZZY PREVIEW=FUZZY STATUS=SIZE SAVEDATE LITERAL+ NOTIFY SPECIAL-USE ACL RIGHTS=texk S[0x55ae8044a600]: 2 OK Capability completed (0.001 + 0.000 secs).

I am using Sogo to test and sometimes Thunderbird to verify it is not a Sogo specific issue. I have currently set these debug options in Dovecot: auth_verbose = yes auth_debug = yes mail_debug = yes Unfortunately this is not enough to get a clue. What more can I do (other debug options?) to figure out what is going on? - Kees

Using dovecot-shared for an shared index not working
by Achim Gottinger 18 Feb '22

18 Feb '22

Hello I'm in the process to migrate our mail server from version 2.2.13 with maildirs to 2.3.13 with sdbox. On the old server if we wanted an common index for the seen flag on shared folders we created an file called dovecot-shared in the mail_location folder and the mailbox folders. This does not work on the new server for all shared mailboxes the seen flag is stored per user. The log file shows this if the seen flag is changed Feb 18 13:24:15 SERVER dovecot[18887]: imap(USER)<18978><51HhlUnYeOfAwAx3>: Debug: imapsieve: mailbox shared/info: FLAG event (changed flags: \Seen) The dovecot-acl file for the shared/info/INBOX folder has the s flag set. I hope i can get a few pointers here how to get the seen flag working for all users again. On the old server the location variable for the shared folders had the variable INDEX defined which can not be used with sdbox. location = maildir:/home/vmail/%%u/mail:INDEX=/home/vmail/%u/mail/shared/%%u:INBOX=/home/vmail/%%u/mail/.INBOX Does that imply that sharing the seen flag can not be used with sdbox?

Dovecot with Microsoft Azure OAUTH2 ?
by Max Kostikov 18 Feb '22

18 Feb '22

Does anyone have experience successfully setting up Dovecot OAUTH2 for authentication with Microsoft Azure? I'm not sure what to use as tokeninfo_url and introspection_url in the Dovecot configuration. I would appreciate any help and advice. -- Best regards, Max Kostikov
