Many thanks to Joseph Tam and Steffen Kaiser for pointing me to the logging information that I should have been using in the first place.

Cache unseen count
by Jorge Carling 11 Feb '16

11 Feb '16

Dear all, Lately I am working on PHP mail account management application. It has, among others, Unread messages count column. To get the number of unread messages, I execute "doveadm search" command for each database row. The search time for single account is about 0.03 seconds. Our system has around 750 accounts, so the total loading time is currently around 20 seconds. When setting up Dovecot, I made the user_query, which is also used to store the message quota, and total number of messages … [View More]

Help migrating a mailbox...
by Willy Gardiol 11 Feb '16

11 Feb '16

Hi! i have a question for you guys, i have been playing with this issue for a while and i am a bit lost. I have dovecot 2.2.16 on a Gentoo linux server, which run a couple of email domains, linked with postfix. I have a huge (>4gb) Outlook PST file which contains a backup coming from a new user, he used to have this backup on his old email system and i need to dump it into his new email account on my server. This is just a "old" backup which needs to be kept for reference, there is no … [View More]need to preserve any ID/UID/GUID whatever. So, i found the "readpst" util which is capable ot reading the PST file and dump it's contents as mbox structure. (see http://bit-vonameln.de/email-migration-outlook-dovecot-imap/) I did it and i got a 4.4gb folder with some sub-folders, attachments, and more files inside. Then i spent most of a few days trying to have dovecot digest this and import it on top of the user new email address. With no luck. I have being trying with doveadm sync but i cannot find how i need to do it. Note that: 1) there is no local user, only the mail user (user(a)hisdomain.org) 2) i use maildir, the PST has been converted to mbox 3) dovecot is compiled with maildir and mbox support I tried, for example: server # export mail_location=mbox:/path/to/mbox/converted/emails server # doveadm sync -u user(a)hisdomain.org -d doveadm(user(a)hisdomain.org): Fatal: User has no mail_replica in userdb Then i tried: server # export mail_location=/home/vmail/hisdomain.org/user/maildir server # doveadm sync -u user(a)hisdomain.org mbox:/path/to/mbox/converted/emails dsync(user(a)hisdomain.org): Error: Mail locations must use the same virtual mailbox hierarchy separator (specify separator for the default namespace) Also tried: server # export mail_location=/home/vmail/hisdomain.org/user/maildir server # doveadm sync -u user(a)hisdomain.org /path/to/mbox/converted/emails doveadm(user(a)hisdomain.org): Fatal: execvp(/home/vmail/hisdomain.org/user/maildir) failed: Permission denied dsync-local(user(a)hisdomain.org): Error: read(remote) failed: EOF (version not received) My dovecot is configured to use "maildir", the most relevant part of my dovecot.conf is: auth_debug = no login_greeting = Dovecot ready. mail_debug = no auth_debug_passwords = no auth_default_realm = mydomain.org auth_mechanisms = plain login auth_realms = <list of my domains here> auth_verbose = no base_dir = /var/run/dovecot/ disable_plaintext_auth = no mail_uid=999 mail_gid=999 listen = * mail_location = maildir:/home/vmail/%d/%n/maildir protocols = imap sieve lmtp (i can add omitted lines if needed) either i am not undesrtanding anything, which is totally possible, or i am missing something big. If anybody on this list has any insight or suggestion, pelase advise! ps: the destination mailbox is perfectly new and empty, it's already existing and the user can successfully login, send and receive emails. Dovecot works great, and i am operating locally on the server where i uploaded the converted mbox folders. -- Willy Gardiol willy(a)gardiol.org www.gardiol.org www.trackaway.org -> Track YOUR way the way you want!

Per-user special folder?
by Richard Platel 10 Feb '16

10 Feb '16

Hi It's possible to mark some folders as special use for IMAP in the config like: namespace inbox { mailbox Spam { special_use = \Junk } } Our webmail allows users to use an arbitrary folder for Spam, and we have this settings and we'd like to return it in from our UserDB (which is a custom dict proxy). For testing were able to set a namespace parameter like "separator" by returning: "namespace/inbox/separator" : "=", from UserDB, but can't figure out a way to set mailbox settings,… [View More]

Load increase and imap processes in state D
by Alessio Cecchi 09 Feb '16

09 Feb '16

Hi, in recent weeks I have notice a sudden increase in the load average of our Dovecot (2.2.19) IMAP/POP servers (and consequently in the NFS storage). After an investigation I found some dovecot/imap processes in D state and running UID FETCH or UID SORT from Webmail (Roundcube) without that user was actually more connected to webmail. Some minutes after the dovecot/imap processes stop to run FETCH/SORT but in "ps aux" I can still see it. If the user try to login in Webmail again the … [View More]same process start again to run FETCH/SORT (and it consumes a lot of I/O resources) but the webmail does not load any message and return a "FETCH 1: UID INTERNALDATE BODY.PEEK ..." error. The only way to restore the webmail access is to kill the related dovecot/imap process (or with doveadm kick username). I noticed that these processes in D state had started many hours before. Example, now are 17:30 (important, see the time of the dovecot/imap processes) the user alessio@skye try to login in webmail without success and close the webmail, processes are still running: # doveadm who | grep alessio@skye username # proto (pids) (ips) alessio@skye 3 imap (10440 4624) (192.168.5.215) # ps aux | grep SORT vmail 4624 0.0 0.0 108792 16048 ? D 13:32 0:01 dovecot/imap [alessio@skye 192.168.5.215 UID SORT] vmail 10440 0.0 0.1 108520 17832 ? D 12:32 0:02 dovecot/imap [alessio@skye 192.168.5.215 UID SORT] # doveadm kick alessio@skye kicked connections from the following users: alessio@skye Processes are now died, and user can login in Webmail easily. Can be a "reusing processes" issue since I have set service_count=100 for imap and pop3 services or there may be other problems related to my configuration?

RFC: HTTP based storage API
by Nagy, Attila 09 Feb '16

Hi, Nearly every popular programming language has an LMTP/POP/IMAP implementation, most of them suck in many different ways. I don't know any server or library which provides a well-established, compatible protocol frontend with an open backend API, which could be used to easily make a custom storage backend for the LMTP/POP/IMAP frontend in any language, in any programming paradigm, irregardless of the frontend implementation. Dovecot is very close to this: it speaks IMAP to the backend,… [View More]

"mail_shared_explicit_inbox = no", but shared INBOX has a "\Noselect" tag?
by Rudolf Körner 08 Feb '16

08 Feb '16

Regarding the given information, it seems to me that the option "mail_shared_explicit_inbox=no" does not work as expected. Quote from NEWS-2.2: mail_shared_explicit_inbox setting to specify if a shared INBOX should be accessible as "shared/$user" or "shared/$user/INBOX" Using Dovecot 2.2.13 and Maildir++ Working on the commandline: # doveconf mail_shared_explicit_inbox mail_shared_explicit_inbox = no # service dovecot restart # ls -lda /mail/reader/Shared/owner(a)example.com/.* … [View More]Shows no (hidden) folders. # telnet 127.0.0.1 143 a0 login reader(a)example.com *** a1 list "" "Shared/owner(a)example.com" * LIST (\Noselect \HasChildren) "/" Shared/owner(a)example.com a1 OK List completed. Is the retrieved "\Noselect" tag correct with the option "mail_shared_explicit_inbox = no"? I would expect the folder "Shared/owner(a)example.com" to be "selectable", because I thought the option "mail_shared_explicit_inbox = no" would make e-mails of a shared INBOX visible directly at the folder "Shared/owner(a)example.com" (which does not work in my case). Note: Shared *sub*folders of an INBOX work as expected. Just to show that the shared INBOX is accessible (note that it is not shown by a list "" "*" here, which is expected with that option): a2 list "" "Shared/owner(a)example.com/INBOX" a2 OK List completed. a3 select Shared/owner(a)example.com/INBOX * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 27 EXISTS Using "mail_shared_explicit_inbox = yes" does show the INBOX as a subfolder of "Shared/owner(a)example.com" and allows accessing the e-mails of the shared INBOX. However, it would be nice (and keep users happy at using their known shared folder layout) to see the e-mails of the shared INBOX at the Shared/owner(a)example.com folder.

external storage for mail attachments
by zucca＠systemschmiede.com 03 Feb '16

03 Feb '16

Hi list! was wondering if it was possible to store mail attachments on a separate storage with dovecot, and if so, how. Of course a single instance storage of these attachments would also be a very good thing, allthough not a basic prerequisite.

Dovecot with Maildir
by John Williams 03 Feb '16

03 Feb '16

Folks, I'm trying to get dovecot to check a for mail in a maildir format on Ubuntu. Mail is being delivered to and from the system. I can send and receive mail using Pine & Mutt. But I cannot seem to get dovecot to work with the maildir. So I can't check for mail using Dovecot. This is what I'm using for reference: https://help.ubuntu.com/community/Dovecot I believe (not sure actually) the answer is in the mail_location variable for Dovecot. This is what I'… [View More]

IMAP ACLs for groups
by Chris 02 Feb '16

02 Feb '16

Dear All, is there any way to assign POSIX groups to Dovecot IMAP-ACLs? I've tried that today, but I could only open a public folder when my username was listed in the ACL. A group didn't work. How do you manage ACLs for intenseley used public folders with many users? What backend do you use for user management and ACLs? Is there any way to extend permissions? Are there any scripts available that set permissions or grant them when logging in? - Chris

Disable Client Certificate Authentication for Unencrypted Connections?
by Haravikk 02 Feb '16

02 Feb '16

I’m using dovecot to provide encrypted IMAP e-mail support for remote clients and it’s working great. However, I also need to set up a webmail front-end (Roundcube), which I’m hoping to have use unencrypted IMAP on port 143 (as only port 993 is available externally). The problem I’m running into is that I want to require client certificate authentication on port 993, but dovecot is apparently requiring a certificate on all connections, which is preventing Roundcube from connecting. Since … [View More]

Autosubscribe but not autocreate?
by azurit＠pobox.sk 02 Feb '16

02 Feb '16

Hi, is it possible to set a mailbox to autosubscribe IF it exists but NOT autocreate if it doesn't exists? We are having problems with users and Spam folders which are not subscribed so users doesn't see e-mails which are saved there. On the other hand, we don't want to recreate Spam folders which were deleted by users (some of them don't want to filter spam so they deleted Spam folder and spam is saved into INBOX). Or is it somehow possible to subscribe to a folder while creating … [View More]

Can you "doveadm search" with mailbox location instead of a user (-u option)?
by Christian Rohmann 02 Feb '16

02 Feb '16

Hey dovecot-users! doveadm import offers to use i.e. a maildir as source and then import into a users mailbox referenced via "-u" option. If one wants to import only certain emails from the source a search-query can be given as well. I was wondering if doveadm search also does offer to search a mailbox referenced by filesystem path i.e. doveadm search maildir:/srv/mailboxes/example.com/mailbox123 NEW Maybe a fixed mailbox location via "-o mailbox_location=maildir:/srv/mailboxes/example.… [View More]

Re-starting replication after a long disconnect

30 Jan '16

Using Dovecot 2.2.15.8 We use dsync as shown at http://wiki.dovecot.org/Replication <http://wiki.dovecot.org/Replication> to have a second copy of our mail store. Users connect to one server and the other is considered a secondary, and is there “just in case”. If one-way backup/sync would make more sense, I would consider that, but at the time we set it up (October 2013), I recall there was some issue with one-way not being as reliable.

Setting Recent Flag on New Messages?
by Haravikk 29 Jan '16

29 Jan '16

So I’m looking at setting up some house-keeping for my dovecot mailboxes, specifically deleting messages in trash, spam etc., by deleting Seen messages older than X days. In order to protect against the edge case of a user reading a message right before the deletion task however I’d like to do something like the following: doveadm expunge -A OLD SEEN BEFORE 7d MAILBOX Trash doveadm flags -A remove '\Recent' SEEN BEFORE 7d MAILBOX Trash (except I’m actually doing this per-user with a script … [View More]

Correct Way to Run expunge for All?
by Haravikk 29 Jan '16

29 Jan '16

So as part of my daily mailbox maintenance I have the following command: doveadm expunge -A DELETED i.e- I’m only expunging messages that have been specifically marked as deleted. I also only do this *after* running doveadm purge, as this means that there is at least a 24 hour window between a message being marked as deleted, and it being gone forever. However I get the following error message: Fatal: expunge: To avoid accidents, search query must contain MAILBOX in all search branches … [View More]

Maildir to mdbox conersion size issue
by Petr Bousek 29 Jan '16

Hello, I have issue with dovecot 2.2.13 I want to change all Maildirs to mdbox format and I do it per partes, so I change mail_location for user (in sql), than I use doveadm sync -u user path_to_maildir and everything works mostly fine. But now I found that when I migrate quite huge Maildir (about 24G of mails) to mdbox, after sync the final mdbox is twice as big as source Maildir (48GB). I tried to find duplicities, but didn't find any. Is there any reason why mdbox consume so much … [View More]
