solr vs fts
by Maciej Milaszewski IQ PL 06 Jul '19

06 Jul '19

Hi I have a question about tunning dovecot-2.2.36.x Mail was stared in storage via nfs in MAILDIR via /home/us/username(a)domain.ltd/MAILDIR/ I use additionally local dovecot_indexes via SSD disk (/var/dovecot_indexes%h) A few clients have 25K and more e-mail I thinking about use solr like: fts = solr fts_solr = debug url=http://IP:8983/solr/ (solr in external machine) Does it make sense ? use dovecot_indexes and fts ? What is the difference in performance?

Email encryption and key protection
by Chris Narkiewicz 05 Jul '19

05 Jul '19

I was reading through Dovecot mail-crypt plugin documentation and I'm wondering what is the benefit of turning the encryption on if private and public keys are both stored on the server? What are the benefits and how the key can be protected (apart from file permissions). Cheers, Chris

Percent character in mail_crypt_private_password not possible
by mabi 04 Jul '19

04 Jul '19

Hello, I am using the mail_crypt plugin with Dovecot 2.3 and have issues trying to use a mail crypt private password which contains a percent "%" character as you can see below: $ doveadm -o plugin/mail_crypt_private_password=SomethingWith\%Percent mailbox cryptokey generate -u email(a)domain.tld -URf doveadm(email(a)domain.tld): Error: Failed to expand plugin setting mail_crypt_private_password = 'SomethingWith%Percent': Unknown variable '%P' Note here that the percent is escaped with a backslash "\%" in order for the shell not to process it.

mail_crypt: multiple keypairs
by mabi 04 Jul '19

04 Jul '19

Hello, I am testing mail_crypt plugin with per account encryption and wanted to generate a new keypair for an account but noticed that I now end up with 2 keypairs where one is active and the other inactive as you can see below: $ doveadm mailbox cryptokey list -u email(a)domain.tld -U Folder Active Public ID yes 7b140b4f3d6d68eed2c59259ac5e6f6a280dc82990292dc415b4100d6c797f67 no 1c1dd1c955757da7c19f1eeb6d6c4d0d66e6355baa2d844bc2623052e1aa2f91 Does this mean now that all existing emails get encrypted with both keypairs? or does this mean only the active keypair is used to encrypt new emails? Is it possible to delete the inactive keypair? if yes how? Regards, Mabi

fts_lucene
by Ignacio García 04 Jul '19

04 Jul '19

Hi everybody... I've inherited 2 servers with dovecot and fts_lucene enabled, which I plan to switch to fts-solr instead. My plan is to disable lucene in dovecot.conf, delete all cache associated files, and start configuring the fts plugin from scratch. I need to make sure that I don't mess up things pretty bad and delete the correct files. Are those to be deleted all dovecot.index* files located in the Maildir folder? Is there anything else I should be aware of? Thanks so much in advance for your kind help! Ignacio

dsync not replicatiing .dovecot.sieve
by Laura Smith 04 Jul '19

04 Jul '19

There was a post on this topic to the list Aug 06, 2018 to which Aki replied "Thank you for reporting this, we'll take a look at this.". But its not clear what (if anything) has happened since ? The problem still seems to exist in 2.3.3 (original report by previous poster was for 2.3.2.1) The scenario I'm seeing is pretty much identical to the original poster's. Mail seems to be replicating fine, but sieve doesn't replicate at all.

I have the following in my active sieve file, and there are no errors logged. if header :contains "to" "+root" { setflag "\\Seen"; fileinto :create "root"; stop; } The message is put in .root, bit is not marked as seen. Is the default action to put mail in a folder matching the extension taking precedence?

mail_replica equivalent to replicator_host/replicator_port
by Laura Smith 03 Jul '19

03 Jul '19

Silly question but regarding https://wiki.dovecot.org/Replication, is the mail_replica parameter shown in the docs equivalent to replicator_host and replicator_port in 2.3.3 ? 2.3.3 doesn't seem to like the mail_replica param (and indeed doveconf -a doesn't show it as an option) Thanks !

Dovecot LMTP mixing up users on multi-recipient mail
by Bernhard Schmidt 03 Jul '19

03 Jul '19

Hi, I've upgraded a mailstore from Debian Jessie (aka oldstable) with Dovecot 2.2.13 to Debian Buster (next stable) with Dovecot 2.3.4.1 today. It worked pretty well, except that we're seeing error messages very similar to this old thread https://dovecot.org/pipermail/dovecot/2015-July/101396.html It appears to be happening when a mail with multiple recipients on this message store is getting delivered through lmtp. Jun 27 11:47:36 lxmhs74 dovecot: lmtp(user1)<47683><sGwaD7eQFF1DugAAgkzuhA:18>: Error: open(/var/cache/dovecot/index/n/user2n/.INBOX/dovecot.index.cache) failed: Permission denied (euid=3814520(<unknown>) egid=12(man) missing +x perm: /var/cache/dovecot/index/n/user2, dir owned by 3391995:12 mode=0700) user1 uid is 3814520, user2n uid is 3391995. Dovecot appears to be trying to deliver the message to user1 while using the index directory of user2n. Further configuration: - message store is on NFS - cache directory is on local disk - users are coming from LDAP, one UID per user user_attrs = cn=user,homeDirectory=home,uidNumber=uid,gidNumber=gid - index directory is calculated from the username maildir:~/Maildir:INDEX=/var/cache/dovecot/index/%-1.1n/%n Despite the error messages (which appear dozens of times per delivery attempt) delivery seems to work. Workaround was to set lmtp_destination_recipient_limit = 1 on the postfix in front of the message store.

Replicate shared folders to warm standby host
by Axel Gluth 03 Jul '19

03 Jul '19

We like to set up our mail system in two datacenters but the wiki<https://wiki.dovecot.org/Replication> says "Shared folder replication doesn't work correctly..." I'm thinking about using an external loadbalancer to ensure that only one host will get connections. Normal operations: client ==imap=> loadbalancer ==imap=> host1 ==replication=> host2 Host1 or Datacenter1 is down: client ==imap=> loadbalancer ==imap=> host2 I see possible problems if host1 comes back and clients connect to host1 before the replication has caught up. But in our case that will be acceptable. Do you consider my idea as safe for production use? Has anybody real world experience with such a setup? Is there a better way to replicate shared folders? Thank you in advance for spending your time on thinking about my problem. Axel

Dovecot/MSQL issue
by Nathan 03 Jul '19

03 Jul '19

Hello, I'm trying to work through an issue that cropped up on a server I've been working on and haven't found a very good workaround. Dovecot is operating in a jailed environment. The configuration in dovecot-sql.conf.ext has been set appropriately with the host=127.0.0.1 (which works from a jailed environment) and when dovecot attempts to auth it appears to perform a reverse dns lookup and overwrites the host with the result localhost before using the msql credentials 'user'@'localhost' which then fails after timing out. I'm currently running version 2.2.33.2 of dovecot. The workaround seems to be to have two credentials for the same user. 'user@'localhost' and 'user'@'127.0.0.1'; postfix operates in a jail as well and works around the jail issue in the same way but doesn't overwrite the specified host with a reverse dns lookup. Anyone have any suggestions on how to handle this issue better? or maybe there's a way to force different behavior which I haven't yet found in the documentation? Any help is much appreciated. Best Regards.

Applying Dovecot for a large / deep folder-hierarchy archive.
by Arnold Opio Oree 26 Jun '19

26 Jun '19

Hello to you all, I'd like to ask about my intended application of Dovecot to create a folder-hierarchy for storing our enterprise emails, which are treated as live data rather than archives for compliance or occasional / reactive retrieval. The data is presently not that large (a few gigabytes), but it is expected to grow rapidly. Up to this stage the data has been containedin a Microsoft Exchange mailbox (2013), and then in an offline PST. The move to the offline PST was by necessity, as the large number offolders, and depth of hierarchy to my best understanding caused the exchange server / outlook / evolution mail clients to begin tomalfunction. To cope with this the archive was broken up and the bulk stored in the offline PST and the most active components stored inonline Exchange mailboxes. I have some understanding of the fs mbox format, and also the mitigations to be made for certain characters / strings. My main concern is whether Dovecot is likely to be able to cope well with a large number of folders / depth of hierarcy. I will really appreciate any help / advice you can give.

Exclude dovecot-uidlist files from a Maildir backup ?
by David Pottage 25 Jun '19

25 Jun '19

Hi, I am using restic to backup my email (stored in dovecot Maildir format) to Amazon S3 As each message is a separate file on disk, and those files don't change after the email has been delivered and read by the user, the incremental backup each day is fairly efficient as it only stored new mails. However, the dovecot-uidlist files change frequently, and are often quite large. The restic backup program detects the file has changed and uploads a new version, but is not smart enough to detect that only a few lines have changed, so it uploads a fresh copy of the entire file to remote storage. I have done some test backups and have noticed, that if I exclude those files from the backup, it completes much faster and uploads far less. Would this be a reasonable policy? My backup is mainly there against unlikely but severe events such as complete hard drive failure, so if I ever had to use it, I would not mind wating for my email client to re-download all my emails. -- David Pottage

Dovecot LDA error - Invalid -f parameter: Invalid character in path
by Bruno de Paula Larini 25 Jun '19

25 Jun '19

Hi list. I'm using dovecot as postfix's LDA. The version is 2.3.6. Last week some spammer set the envelope's FROM to "foo@bar@domain.com" (with two @). While trying to deliver (as this one didn't hit the spamassassin's score), dovecot said the following: Jun 21 02:35:58 mymailserver postfix/pipe[29736]: ADA268195E: to=<user@mydomain>, relay=dovecot, delay=0.08, delays=0.03/0.02/0/0.04, dsn=5.3.0, status=bounced (command line usage error. Command output: lda: Fatal: Invalid -f parameter: Invalid character in path ) Which caused postfix to put it on the bounce list, but the spammer's destiny don't really exist. I could successfully mimic the spammer using telnet and putting two @ in "mail from" address. I don't think this should be an expected behaviour, right? Or is this some config based error? Thanks!

Authentication against multiple mysql databases
by Graham S. Jarvis 24 Jun '19

24 Jun '19

Hello, I have setup authorisation against a mysql database. I'd now like to do (additional) authentication against another mysql database. i.e. I have two databases with usernames and passwords and I'd like allow all the users from both databases to be able to login to IMAP. Can I simply extend 10-auth.conf in conf.d with additional !include files - like auth-sql.db1.conf.ext auth-sql.db2.conf.ext and associated filed etc. Or do I have to create a new database and set up a view onto the other two databases / tables? Any ideas? Thanks, -Graham-

Re: Mail migration problem
by Germán Herrera 24 Jun '19

Well, judging by the error message it appears like dovecot hasn't been compiled with support for maildir, which is strange because I don't see any way to disable in the compile-time options. Are you using the precompiled package from the distro or compiling dovecot by yourself? Could you share the output of "dovecot --build-options" and "dovecot --version"? Thanks!

quota-plugin + namespace with wildcards?

Hi all! Is the quota-plugin (quota + quota-rule directives) supposed to function for namespaces that are generated dynamically for shared mailboxes?
