Can master users retain private \Seen flags ?
by tuuialou 02 Mar '21

02 Mar '21

Hello, I am trying to setup a shared mailbox for a small team. Let's say Alice and Bob both need to read and answer sales(a)example.com. I would like Alice and Bob to retain private \Seen flags on sales(a)example.com. I know I can achieve that with INDEXPVT on shared or public mailboxes but I am not 100% happy with this solution because: - Thunderbird displays sales(a)example.com/Inbox and sales(a)example.com/Sent as "subscribed folders" within alice(a)example.com and bob(a)example.com. So Alice and Bob can't use the unified view of Thunderbird. - I need create a special identity in Alice and Bob Thunderbird's configuration so the sender is sales(a)example.com when Alice or Bob sends an email from sales(a)example.com (and not alice(a)example.com or bob(a)example.com) But I am not sure another email client is able to do that (on a mobile phone for example). - I need to add ACL rights if a new folder is created under sales(a)example.com. So I am now looking at the "master users" feature of Dovecot to replicate this MS Exchange setup https://www.en.its.aau.dk/instructions/Mail/shared-mailbox-thunderbird/ (alice(a)example.com and bob(a)example.com log is as sales(a)example.com) I achieved that but I don't know how to retain private \Seen flags so that Bob doesn't see an email as read even if Alice has marked it as read before. Is it possible to retain private \Seen flags with master users? If yes, how can I achieve that? Thank you for any help! PS: I posted the same question on https://forum.iredmail.org/post77816.html and https://forum.iredmail.org/topic13549-proposal-for-a-exchange-like-shared-m… but I couldn't get help and was advised to ask here.

Failed to map transaction log path - Stale file handle
by Gonzalo Palacios Goicolea 02 Mar '21

Hi All, We recently moved from RHEL6 to RHEL7 and updated dovecot from dovecot-2.2.10-1_14.el6.x86_64 to dovecot-2.2.36-8.el7.x86_64. We use NFS for storing the mail, and 5 servers running at the same time. Before updating dovecot we stopped the service and deleted all dovecot.index* files Now we're experiencing some problems. For example, when deleting an email it is note deleted and appears again duplicated. These are the logs: Feb 28 08:50:42 server5 dovecot: imap(user@domain): Error: Index path/Maildir/dovecot.index: Lost log for seq=5 offset=228: Missing middle file seq=5 (between 5..4294967295, we have seqs 4): Log is locked - newer log can't exist (initial_mapped=1, reason=Index mapped) Feb 28 08:50:42 server5 dovecot: imap(user@domain): Warning: fscking index file path/Maildir/dovecot.index Feb 28 08:50:42 server5 dovecot: imap(user@domain): Error: Failed to map transaction log path/Maildir/dovecot.index.log at sync_offset=10328 after locking: pread() failed: Stale file handle Feb 28 08:50:42 server5 dovecot: imap(user@domain): Error: Index path/Maildir/dovecot.index: Lost log for seq=5 offset=228: Missing middle file seq=5 (between 5..4294967295, we have seqs 4): Requested newer log than exists - still after NFS flush: Log inode is unchanged (initial_mapped=1, reason=Index mapped) Feb 28 08:50:45 server5 dovecot: imap(user@domain): Error: Failed to map transaction log path/Maildir/dovecot.index.log at sync_offset=10328 after locking: pread() failed: Stale file handle Feb 28 08:50:45 server5 dovecot: imap(user@domain): Error: Failed to map view for path/Maildir/dovecot.index: Missing middle file seq=5 (between 5..5, we have seqs 4): Requested newer log than exists - still after NFS flush: Log inode is unchanged Usually restarting the email client solves the problem for a while. We've tried deleting the indexes but it happens again some time later.

Issue with masterauth
by Samuel Mutel 02 Mar '21

02 Mar '21

Hello, I would like to setup masterauth account to be able to connect to imap to log in as other users without password. My users are currently setup in LDAP and it is working correctly. I follow the page https://doc.dovecot.org/configuration_manual/authentication/master_users/ to setup this but I think I forgot something. When I try to login with telnet: Master user logging in as toto => it seems that i can connect with master user ldap(toto,127.0.0.1,<quR66Hm8KgB/AAAB>): invalid credentials => however ldap is request for password check, why ? Normmally the goal of master user is to not specify the password of the final user... Thanks.

Search is uninterruptable
by van der Kamp, John 01 Mar '21

01 Mar '21

Hi, When a user is doing a search, and the data is not indexed, then a search can take a very long time. It seems that search process is uninterruptable. The IMAP connection gets a status message with an ETA every so often, but an administrator on the server cannot stop it. Any SIGTERM or doveadm kick is ignored. Also, when the client times out (it seems clients are not seeing the ETA as a reason to keep the connection open) and the client disconnects is this search process continuing, even though any write to the socket would return an error. I believe the server is stuck in this loop: https://github.com/dovecot/core/blob/master/src/lib-storage/index/index-sea… Somehow the server needs to check for disconnected clients and let the session be kicked from the server too. You probably know better what to do about this then me.

dsync and sieve again
by Edgaras Lukoševičius 01 Mar '21

01 Mar '21

Hi, I'm starting to wonder if dsync is supposed to sync sieve scripts at all? Or should it work only as a part of replicator? Because I was not able to get it working on multiple Dovecot and Pigeon versions, and I see lots of replication/dsync and sieve related questions in the mailing list. I'm trying to get it to work using latest versions on http://repo.dovecot.org/ce-2.3-latest repo. The versions I am testing at the moment are: - Dovecot 2.3.13 (89f716dc2) - Pigeonhole 0.5.13 (cdd19fe3) It's a straightforward setup, nothing fancy. So the question is - is it supposed to work at all without replicator?
