dovecot dict protocol
by Peter Hudec 09 May '19

09 May '19

Hi there is there any written specification for dovecot dict protocol instead of the code? Small example is in docs on https://wiki.dovecot.org/AuthDatabase/Dict and theere is link for all commands/reply in the code https://wiki.dovecot.org/AuthDatabase/Dict I’m writing small dict server and need some explanation for CMD: I, what does the flags means and how should the result looks like CMD: D, I thing this is the same as C, but coud be done later /async/ The reply codes are not very clear. I understand O, N, F. The rest is strange to me. Maybe this is good question do devel mailing list. regards Peter

UID to file?
by Carles Pina i Estany 09 May '19

09 May '19

Hello, In the past I was in a situation that given an email UID I wanted to know which file in the Maildir directory this UID was saved. I did a small parser for $HOME/Maildir/dovecot-uidlist where, if the file had: 1000 W1838 S1796 :1557351041.10447_1.example I would ask for the UID 1000 and would return :1557351041.10447_1.example (and I knew that it was in $HOME/Maildir/new) Is there any other way using dovecot tools to do the same, to avoid parsing an internal dovecot file? Thank you! -- Carles Pina i Estany GPG Key 0x8CD5C157

Push Notification clarification (MessageNew w/o LMTP or LDA)
by Christian Balzer 09 May '19

09 May '19

Hello, Both the examples on the Push Notification wiki page and the XAPS plugin docs seem to suggest or state that LMTP/LDA is required. However IMAP IDLE notifications work without either of these (please no religious discussion of why Dovecot LMTP is the best thing since sliced bread and that everybody should use it). The LUA part of the push notification docs however states that events other than MessageNew are supported. So my question is, when not using LMTP/LDA and a LUA script and of course the correct mail_plugins definition (either global or for IMAP), will a message delivery trigger MessageNew?

How to auto-subscribe to virtual namespace/prefix?
by MRob 09 May '19

09 May '19

In virtual namespace I can have: namespace myvirt { location = blah prefix=Virtual/ separator=/ mailbox "My folder" { auto = subscribe } } And i see email clients successful display subscribed "My folder" but the top-level prefix "Virtual/" is not subscribed. I see the Virtual/ prefix available as a noselect folder in the list of unsubscribed folders and if I manual subscribe to it, folder tree display is perfect. So how can i also make auto-subscription to the "Virtual/" prefix noselect folder?

dsync to backup to directory?
by Felipe Gasper 08 May '19

08 May '19

Hello, We have a hosting operation and are interested in offloading mail for some of our machines to a separate machine. We want the ability, though, to migrate accounts between the “offloaded” and “unified” configurations. Toward that end, is it possible to “merge” two different mail directories (either maildir or mdbox) via doveadm? “doveadm backup” looks like the closest match, but it doesn’t appear to accept an arbitrary directory as its synchronization source. Thank you! -Felipe Gasper Mississauga, Ontario

Dovecot does not recognize imported messages

Today I tried to import mail directly on the server's home directory on the server. I copied it directly. I didn't use the imap protocol. Dovcot didn't recognize these emails. I didn't display these imported emails on my page, recalculating disk quotas. It will not increase the used capacity. I try to send an email to this user, dovcot recognizes all the emails, and recalculates the disk cooperation, this time is correct.

Symlinked mailboxes and dovecot-uidlist.lock
by Dave 07 May '19

07 May '19

I have a scenario where I have two users, one account (user1) with it's own Maildir account, and another account (user2) (which I wish to see the same messages) with a symlinked Maildir to user1's Maildir. I.E.: /home/user1/Maildir /home/user2/Maildir (where this Maildir is symlinked to /home/user1/Maildir) Both users are in a group together (usergroup), and so all of the permissions on the Maildir, new, cur, etc folders are rwxrwx--- or rw-rw----. All mail gets created and delivered correctly, both users can move and create files, and everything generally seems to be working fine. However, I did notice one error showing up in the system logs: May 2 11:35:13 userserver dovecot: imap(user1): Error: inotify_add_watch(/home/user1/Maildir/dovecot-uidlist.lock) failed: Permission denied May 2 11:36:27 userserver dovecot: imap(user2): Error: inotify_add_watch(/home/user2/Maildir/dovecot-uidlist.lock) failed: Permission denied May 3 10:10:11 userserver dovecot: imap(user2): Error: inotify_add_watch(/home/user2/Maildir/.Folder1/dovecot-uidlist.lock) failed: Permission denied I've managed to catch a glimpse of a lock file, as it comes and goes very quickly, and it is permissioned as so: -rw-rw---- 1 user1 usergroup 10 May 5 11:39 dovecot-uidlist.lock So I'm not sure what exactly the permissions issue is then? The file seems to have the appropriate group permissions for each user to read from and write to it. Again, this is the only error I'm getting, and everything has been working fine. I did read the Dovecot wiki talking about symlinking mailboxes, and it refers to symlinking each box/folder individually and not the entire Maildir folder as I've done, but since each individual box/folder has its own dovecot-uidlist I imagine I might run into this same issue anyway? Anyway, I'd like to squelch the error if I can, so are there any thoughts as to why the lock files are having trouble with inotify_add_watch? -Dave

doveadm - mailbox to filesystem directory?
by Joaquin F 07 May '19

07 May '19

Is it possible to get the filesystem location (directory name) for a given mailbox? The closest I found was parsing the output of "doveadm -D mailbox create", but this only works if the mailbox doesn't exist yet and prone to failure if the debug output changes in future versions. Using "doveadm mailbox mutf7" helps, but there's some ASCII characters which are encoded. So far I've found "\" turns in to "\5c", "." into "\2e" and "/" to "\2f" and the separator to ".". But maybe there are others. Thanks in advance. Version: dovecot 2.2.36 (1f10bfa63) Relevant config: mail_location = maildir:~/Maildir protocols = imap namespace inbox { separator = "$" }

regression with lmtp_hdr_delivery_address in 2.3
by dovecot-ffe7＠ryanc.org 07 May '19

07 May '19

Hi, In my LMTP config, I have lmtp_hdr_delivery_address = none. Under 2.2, Received headers looked like this: Received: from smtp.example.com by lmtp.example.com with LMTP id +IVdKS81cFwWagAAGhmRSA ; Fri, 22 Feb 2019 17:45:19 +0000 After the update to 2.3, they look like this: Received: from smtp.example.com by lmtp.example.com with LMTP id MJbKAMFEclyKCQAAGhmRSA (envelope-from <yyy(a)example.net>) for <xxx(a)example.com>; Sun, 24 Feb 2019 07:16:17 +0000 In both cases I *do not* have a "Delivered-To" header I do see a check for rcpt_to == NULL in the smtp_server_transaction_write_trace_record function, but it looks like the lmtp_local_add_headers function does not update the transaction, so it doesn't get pulled in. Also, the LMTP settings struct isn't exposed in that function currently, and I'm not sure how to add it. In 2.2, both the "Delivered-To" and "Received" headers were handled by client_get_added_headers. Please CC me in replies, as I am not subscribed to the list. Thanks, Ryan

There is random failure in test-http-payload when building rpm package from 2.3.6.

dynamic virtual mailboxes?
by MRob 06 May '19

hi, I spent time learning about virtual mailboxes. Is there some way to create dynamic virtual mailboxes? I mean, when I look at a mailbox, I want to see only unread messages or flagged messages in that mailbox.

Understanding virtual mailboxes (examples in 15-mailboxes.conf)
by MRob 05 May '19

05 May '19

The examples in 15-mailboxes.conf # If you have a virtual "All messages" mailbox: #mailbox virtual/All { # special_use = \All # comment = All my messages #} # If you have a virtual "Flagged" mailbox: #mailbox virtual/Flagged { # special_use = \Flagged # comment = All my flagged messages #} They seem to reference some kind of virtual mailbox setup that doesn't compare to the docs for the "virtual" plugin. That plugin says we should create a separate namespace instead, like "namespace virtual" and put files representing the virtual folders into user maildirs. What if we use mdbox? add the files to user/mailboxes director I will guess. Is there a way to use the mailbox examples in the inbox namespace in the default config? Does it use some other method different from the virtual plugin? maybe more config hints for those examples would be helpful. Thank you.

Feature request: exclude IP/network in allow_nets extra field
by Zhang Huangbin 01 May '19

01 May '19

Dear all, We use `allow_nets`[1] to restrict login clients, it works fine. Recently we need to allow some users to login from everywhere except some IP/networks, how can we accomplish this with "allow_nets"? Tried allow_nets="!a.b.c.d", but Dovecot reports error "allow_nets: Invalid network '!a.b.c.d'". Can we have this feature? i guess it should be done in function "auth_request_validate_networks"[2] in file src/auth/auth-request.c. [1] allow_nets: https://wiki.dovecot.org/PasswordDatabase/ExtraFields/AllowNets [2] https://github.com/dovecot/core/blob/fbc3ccc4a9a02b82073585a33254eacedc6a99…

Pigeonhole release 0.5.6
by Aki Tuomi 30 Apr '19

30 Apr '19

Hi! We are pleased to release Pigeonhole 0.5.6 for Dovecot 2.3.6. Tarball https://pigeonhole.dovecot.org/releases/2.3/dovecot-2.3-pigeonhole-0.5.6.ta… https://pigeonhole.dovecot.org/releases/2.3/dovecot-2.3-pigeonhole-0.5.6.ta… Binary packages can be found from https://repo.dovecot.org/ Changes + sieve: Redirect loop prevention is sometimes ineffective. Improve existing loop detection by also recognizing the X-Sieve-Redirected-From header in incoming messages and dropping redirect actions when it points to the sending account. This header is already added by the redirect action, so this improvement only adds an additional use of this header. - sieve: Prevent execution of implicit keep upon temporary failure occurring at runtime. --- Aki Tuomi Open-Xchange oy
