sender rewriting scheme
by Mathieu Gosset 01 May '20

01 May '20

Hello, I would like to know if dovecot/pigeonhole provide a way to do sieve redirection with sender rewriting scheme (srs)? I apologize in advance if that e-mail address isn't meant for assistance, but I've asked on the official irc channel on freenode and was told to direct my query to dovecot(a)dovecot.org, I hope you won't mind. Thanking you in advance Best Regards Mathieu Gosset

Shared folder replication - query - can it be replicated?
by Daniel Botting 01 May '20

01 May '20

Hi, Further to my earlier posting to the mailing list this morning regarding replicating of public namespaces is it possible that a shared name space can be replicated: https://wiki.dovecot.org/SharedMailboxes/Shared We use LDAP, the thought being that an LDAP service account is created and the corresponding mailbox is shared to other mail users on the server. Kind regards Daniel

Public folder replication ( not replicating) - roadmap query
by Daniel Botting 01 May '20

01 May '20

Hi, We have a server pair running Dovecot 2.3.10 (latest stable) version directly from repo.dovecot.org and have mailbox and sieve replication working as required in production. I have setup a test pair with the exact same configuration and on each server setup public name space for a mailbox address such as jobs@ where multiple users would need to subscribe to this to view recruitment emails. This is not replicating as per the advice on the below url: - https://wiki.dovecot.org/Replication Is there an easily maintainable workaround at this time and is this on the roadmap for the developers, if so what time scale is being envisaged? Kind regards Daniel

Sorry for all the notes; I'm trying to have postfix 3.4.8, trying to authenticate postfix against Dovecot 2.3.4.1 passwd-file, using lmtp.

Header search on Dovecot with SOLR
by Ricardo Machini Barbosa 28 Apr '20

28 Apr '20

Hello, I am using dovecot 2.3.0 with FTS Solr 7.7.2. I started having problems where the solr stopped working, I came to the conclusion that when a specific user is accessing his email, the queries made on SOLR are dropping this service. Apr 28 11:03:59 Error: imap(tullio(a)dominio.com.br)<125772><fdHRQlqkupe6zZkj>: fts_solr: Lookup failed: Request timed out (Request queued 180.186 secs ago, 2 times retried, 3 send attempts in 180.185 secs, 60.062 in last attempt, 60.063 in http ioloop, 0.000 in other ioloops, connected 60.062 secs ago) Analyzing the solr logs, we got an example query: http://127.0.0.1:8983/solr/dovecot/select?wt=xml&fl=uid,score&rows=15824&sor t=uid+asc&q=%7b!lucene+q.op%3dAND%7dhdr:%3ceyJlX21faWQiOjE1ODUxMiwidF9pZCI6O DUxMCwiZV9jX2lkIjoxLCJjX3BfdF9pZCI6MywiY19pZCI6MzQ4MzIzMDUsImVfaWQiOjg3NjYwL CJlX3RfaWQiOjYsInRzIjoiMjAyMC0wNC0yNCAxOTozMjoxMS4wIn0%3d(a)edrone.me%3e&fq=%2 Bbox:8ba9c7227a37835cbaf20100b047fe86+%2Buser:tullio@dominio.com.br What I could see is that this query in question was a search in the headers and not in the body. Should this query type go through FTS Solr? Reading the documentation I understand that the standard behavior is that header searches are made by dovecot and only bodies searches are made by Solr. I saw about a recent option called fts_enforced, where it is possible to forward header searches to FTS, but I am not using this option. I would like to know if my understanding is incorrect or if there is some kind of problem with dovecot? Regards, Ricardo

Dovecot LDAP/AD with exim as mta
by Benoît PELISSIER 28 Apr '20

28 Apr '20

Hi, I have done configuration dovecot/exim/samba4ad. I use dovecot-lda not exim to deliver mail. And dovecot to authentify users. I have users with mail address on AD. When i sent mail to user mail address, its working. I have distribution group or group with mail address on AD and users as member of this groups. But when i send mail to group mail address, its not working Dovecot-lda can do it ? Or i need do it with exim (or postfix) ? Thanks Benoît

Quota calculation with MySQL backend and replication.
by Reio Remma 27 Apr '20

27 Apr '20

Hello! Over the weekend I converted our Dovecot server from Maildir quota to MySQL backed quota and then provisioned a fresh replica server and seeded it via Dovecot replication. This morning most mailboxes were over quota, reporting twice the actual usage. I'm fairly certain it's the effect of having sql backed quota with both Dovecot servers using the same database. Can anyone tell me if this is a one-off problem stemming from replicating the 2nd server from scratch or should I be aware of other quirks concerning sql backed quota and replication? Thanks a bunch! Reio

Hierarchy separator recommendation?
by Admin Beckspaced 27 Apr '20

27 Apr '20

Dear dovecot list, I'm using Maildir as mailbox format. Is there any recommendation for the namespace hierarchy separator? Currently I didn't set any. So it is the default of dot '.' I'm switiching from a rather unknown IMAP Server called DBMail (http://www.dbmail.org/) Planning to synchronize the mailboxes via imapsync (https://github.com/imapsync/imapsync) Is there anything I should be thinking / planning about? Or can i always change this namespace hierarchy separator later on? Any hints or insights are more than welcome ;) thanks & greetings Becki

User's mail encryption with mail-crypt-plugin
by André Rodier 26 Apr '20

26 Apr '20

Hello, I have a question about the "mail-crypt-plugin". If each user is having its own mail encryption key, is there a way to encrypt the key with the user password, and to decrypt it when the user logs in? I want to, if this is possible, to prevent any user, even root, to access another user's emails. Thanks, André
