feature request: add base64 variable modifier
by alex 19 Dec '22

19 Dec '22

Hi, It would be very convenient to have a base64 variable modifier. Main use-case is to base64-encode passwords when changing your hashing scheme. With a base64 encoding modifier (e.g. %B) something like this would safely work: userdb { driver = prefetch default_fields = plain_pass=%Bw } without things breaking when there are %-characters in the password, and without having to send the plaintext password to the database, as current solutions propose, which is never a good idea. alternative solution: adapt the generic hash-modifier to accept a none/plaintext hashing-scheme and use the base64 output functionality that is already available there. Thanks! Alex

What do I do with the ".ext?"
by James Moe 18 Dec '22

18 Dec '22

dovecot 2.3.15 opensuse LEAP 15.4 I am installing dovecot and have postfix as the SMTP agent. It also needs to use a MySQL database. In </etc/dovecot> there is the main dovecot.conf file, and a number of other files with the extension ".conf.ext." It is not clear how to use these. I could nothing in the documentation that discusses it. Do I copy one, say dovecot-sql.conf.ext, modify it: - rename the copy without the ".ext?" - or move the copy to the "conf.d" directory, with or without the "ext?" -- James Moe moe dot james at sohnen-moe dot com 520.743.3936 Think.

2.3.14: stale imap-login processes due to bogus user setup tying up process limit
by Volker Stolz 16 Dec '22

16 Dec '22

I just dealt with an interesting Dovecot issue on our small server, and thought I might share it. I also feel that although in the end it was a configuration error, Dovecot should somehow avoid leaving this processes around and hence filling up the process limit quickly. - set up Dovecot IMAP on Debian buster (either with the older 2.3.x Debian package, or 2.3.14 from the dovecot-repo) - config: ... namespace inbox { inbox = yes location = ... default settings ... ... passdb { args = scheme=HMAC-MD5 username_format=%u /etc/dovecot/users driver = passwd-file } protocols = " imap" ... userdb { args = blocking=no driver = passwd } ... - secret sauce: have a user in the passdb that doesn't have a physical account on the system yet (we were migrating to a new machine). The log-file shows successful authentication for that user (after we flipped DNS to point to this new machine), but over time (2-3 times/day) we were left with an increasing number of `imap-login` processes in state `pre-login`, eventually requiring a dovecot restart. Dialling up process_limits didn't seem to help, we'd just get more of these stale processes. After creating the user on the system, the behaviour reverted to normal, no more stale processes. I do not know what error message that user received on their end, but since we announced we were migrating, they probably just ignored it and thought it as part of the transition. Best, Volker (a happy & long Dovecot user)

Kerberos/GSSAPI auth weirdness?
by r3pek 14 Dec '22

14 Dec '22

Hi list! I'm migrating my server into a new REALM (INT.R3PEK.ORG) from an old one (R3PEK.ORG) This is a completely new install and configuration, so no leftovers exits. The machine is correctly register into the REALM and users are able to login without a problem. Now, when I try to login using a Kerberos ticket, for some reason that I can't understand, dovecot is looking for a ticket on the old REALM. Maybe because of the email domain (which stayed the same)? This is the error message I see on the clients: "Failed to authenticate: Server krbtgt/R3PEK.ORG(a)INT.R3PEK.ORG" The one it should be looking for is krbtgt/INT.R3PEK.ORG(a)INT.R3PEK.ORG, but I can't seem to figure out where the problem is. # doveconf | grep -i realm auth_default_realm = INT.R3PEK.ORG auth_realms = INT.R3PEK.ORG What do I need to change to make this work?

Backups
by Doug Hardie 11 Dec '22

11 Dec '22

I started to investigate using doveadm backup to backup my mail system. I have a small number of users and the mail store is not large. It uses maildir format. I setup a test system that is not connected to the internet and started up dovecot. I used the following command to backup one user: doveadm backup -u ben remote:test ben is the user is in the mail store. Test is the actual server name. That worked just fine. The maildir was copied completely (as best as I can tell with ls). Then I tried the second user: doveadm backup -u jean remote:test This gives 2 error messages: doveadm(jean)[]<McRYOFI0jGN1MwAAmC+70w>: Error: Mailbox INBOX: Failed to get attribute vendor/vendor.dovecot/pvt/server/sieve/files/.dovecot: Mailbox attributes not enabled doveadm(jean)[]<0IwxIlI0jGMgUwAAZU03Dg>: Error: Remote command returned error 65: ssh test doveadm dsync-server -ujean -U In addition, the maildir directories are created, but there are no emails in any of them (e.g., cur). What is the problem with the 2nd and why does it behave differently from the first? -- Doug

Sieve duplicates
by Ferenc 09 Dec '22

09 Dec '22

Hi list, I have Sieve scripts that unintentionally duplicate e-mails. My dovecot version is 2.3.4.1 (f79e8e7e4), Pigeonhole version 0.5.4 on Linux 5.4.189-2-pve x86_64 Debian 10.13. My scripts get called on an imap COPY action (imapsieve extension). The mail is fed to an external script (spam/ham training) via a pipe :copy action (vnd.dovecot.pipe extension). An header is added to keep track of what happened (editheader extension). I use "if header :contains” for my (simple) logic. If contains header X, do this, add header Y. If contains header Y, do that, add header X. I end each "if” part with keep; and stop; commands. Simple versions of this script, without the if-then construct, seem to work ok. As soon as I try to use if-then-else I find a duplicate of the processed e-mail; one that seems to be untouched, one that appears to have been processed. I hope I’m making myself clear… # without if-then require … pipe :copy … addheader … keep; # with if-then require … if header :contains pipe :copy … addheader … keep; stop; if not exists pipe :copy … addheader … keep; stop; keep; The scripts get called from for instance imapsieve_mailbox1_before. Cheers, Ferenc

Seen Flags per User

Hello, i want to configure seen flags per user for shared public mailboxes in dovecot. I have added the INDEVPVT Option to the location parameter in the namespace and restarted the services and the server.

access dict in lua auth script

Hi! I want to access a configured dictionary in a lua authentication script. Unfortunately the documentation <https://doc.dovecot.org/admin_manual/lua/> does mention a dict object but no way to get one. I also did not find any lua tests in dovecot's source code. Is using the built-in dict not supported? Cheers, Tobias Florek

moving messages between namespaces go into purge
by Marc 07 Dec '22

07 Dec '22

I think it would be nice to have an option where the moving of messages between namespaces (by automated server scripts) would not result in messages ending up in the 'purge' queue. Currently when you move these copied messages, they end up in the purge queue combined with messages that users deleted. I am more or less forced to purge the mailbox after moving GB's while I prefer not to do this, because I would like to keep the opportunity to recover from the purge queue. Maybe there is a way to 'deduplicate' this purge queue?

Sieve: fileinto a subfolder of inbox

Hi everyone! I'm trying to write a sieve script that moves emails to a *subfolder* of the inbox. My script: require ["envelope", "fileinto", "mailbox"]; if anyof( address "to" "support(a)domain.cc", address "cc" "support(a)domain.cc", envelope "to" "support(a)domain.cc" ) { fileinto :create "INBOX.support"; } But this creates a new "support" folder BESIDE the inbox, not INSIDE it.

Backups and disaster recovery
by GDS 04 Dec '22

04 Dec '22

Hello all! After reading some of the past threads on backups, I was wondering if I could get a sanity check... I run a Maildir configuration for a small (10 mailboxes) mail server. Using "doveadm backup", for each mailbox I do: - Weekly full backups and then copy the files to a network-based filesystem.- Daily incremental backups and then copy the files to a network-based filesystem. My recovery assumption is that in case of hardware failure, I would re-set up the mail service and for each mailbox I will recover at the right directory the latest full mailbox backup and on top of it, each incremental backup to the latest day. Does this sound like a sound strategy? Also, I was thinking of setting up a second dovecot server on another server and replicating my primary on an hourly basis to decrease recovery time. But I looked at mbsync and it seems to require mailbox login/password for each mailbox (which I don't have). Is there an alternative? Thank you!

HIGHESTMODSEQ not increasing
by Ronny Forberger 04 Dec '22

04 Dec '22

Hi, I have a problem with my Dovecot IMAP Server on Debian Linux. I migrated it from FreeBSD to Debian, but since then the HIGHESTMODSEQ value for INBOX is not increasing, when I receive new e-mail.

I have tried the commands doveadm index and doveadm force-resync on the INBOX, without any change. My filesystem where the mailboxes reside is on ext4. Can you help me what is wrong?

Doveadm Move Query
by Simon B 01 Dec '22

01 Dec '22

I have a production Dovecot problem and although I searched the mailing lists, I could not find an answer and I hope you can give me a quick answer/pointer in the right direction. I have mails for a user (user(a)domain.net) under /var/spool/mail/virtual/ domain.net/user and I want to move ALL the mails to /var/spool/mail/virtual/domain.com/user If I use #doveadm -Dv move -u user(a)domain.net Maildir:/var/spool/mail/virtual/ domain.net/user Maildir:/var/spool/mail/virtual/domain.com/user ALL I get doveadm(root): Fatal: Unknown argument MAILDIR:/var/spool/mail/virtual/ domain.com/user if I use #doveadm -Dv move -u user(a)domain.net Maildir:/var/spool/mail/virtual/ domain.net/user /var/spool/mail/virtual/domain.com/user ALL doveadm(root): Fatal: Unknown argument /var/spool/mail/virtual/ domain.com/user What the hell am I doing wrong!? :) Thanks.

bug: ARGON2 hash selection incompatible with LDAP
by Krisztián Szegi 25 Nov '22

25 Nov '22

Good day to all, this is my first post to the mailing list! I'd like to report that non-binding auth to (Open)LDAP doesn't work if the latter hashes passwords with ARGON2. Although dovecot (I am using http://2.3.19.1) does support ARGON2 with libsodium, but it doesn't recoginize hashes beginning "{ARGON2}$argon2id$" stored (and hashed, using ppolicy module's hashCleartext) by OpenLDAP. Now, I understand that ARGON2I, -D, and -ID are not compatible, but the ACTUAL algorithm is there between the two $. Furthermore, I think dovecot is in the minority here, I haven't met any software that specifies the ARGON2 subtype between {}. BTW, I haven't met any software that hashes passwords with ARGON2, but not with the ARGON2ID subtype (where libsodium is available, which also seems to be the standard here), as THAT is the recommended one anyway. I patched the rpm in OpenSUSE repo to alias {ARGON2} to {ARGON2ID}: https://build.opensuse.org/package/view_file/home:Samonitari:branches:openS… Could we get something like this (but maybe more correct) into the official source? Maybe a config switch to alias it runtime? Thanks for the attention: Krisztián

compiled sieve files svbin ?
by jeremy ardley 23 Nov '22

23 Nov '22

Hi, I have recently started using claws mail to manage my user sieve scripts using server dovecot-sieve_1%3a2.3.13+dfsg1-2_arm64.deb I originally edited ~/.dovecot.sieve to hold my script and I recall that ~/.dovecot.svbin was automatically generated on first use. (either that or I have forgotten that I had used sievec) Later I used claws mail to generate sieve scripts but they were written into directory ~/sieve/ In experimentation I changed ~/.dovecot.sieve into a link to my principal script ~/sieve/main.sieve The oddity now is that sieve seems to be working when there is no compiled version Should I expect a compiled .svbin version to be generated from claws client? Or generated by first run of the sieve server on the user account? Or should I manage the scripts with claws, but log in to the server later to generate the .svbin versions? In any event what effect does not having a .svbin version have on typical small installation? -- Jeremy

Dovecot 2.2 to 2.3 migration
by Markus Wienhöfer 17 Nov '22

17 Nov '22

Hi, we are currently using Dovecot 2.2 (from the Ubuntu 18.04 repos) and would like to migrate to 2.3 I have read the migration documentation regarding the configuration changes. Apart from that, is it feasible/possible to change from Ubuntu to official Dovecot repositories and upgrade the dovecot package this way? Or is there anything else we should be aware of? Best regards Markus
