Issue creating mailboxes

My Dsync isn't replicating 'EXPUNGE' IMAP command

Hi! I have two Dovecot-2.2.13 servers with Dsync Replication: server1 and server2. When I execute 'EXPUNGE' on server1 side, the messages with FLAG \Deleted are expunged only on server1. The message is still present in Server2. Could someone give me a hint reason for this ?

Case sensitivity
by John Oliver 15 Sep '14

15 Sep '14

I think I've answered my last question by changing mail_location But I'm still getting duplicate mailboxes: [joliver@localhost ~]$ sudo ls -l /var/vmail/ total 8 drwx------. 3 vmail vmail 4096 Sep 11 10:30 testuser1 drwx------. 3 vmail vmail 4096 Sep 11 10:36 testUser1 The cn for my user is 'testUser1', and that's where postfix writes mail. But dovecot wants to use 'testuser1', even if I log in as 'testUser1' I suppose one answer may be to try to get postfix to always use lower-case, but in case that can't happen, how can I get dovecot to ignore case when looking for mailboxes? -- *********************************************************************** * John Oliver http://www.john-oliver.net/ * * * ***********************************************************************

Per-folder (per-mailbox) message expiration with control from client side — is it possible?
by Lev Serebryakov 15 Sep '14

15 Sep '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 I'm migrating from «old skool» solution with one mail client (MUA) on one computer, which retrieves mail via POP3, sorts it and manages it locally to installation when there are several MUAs on different devices, accessing mail via IMAP4, and all sorting and management should be server-side. Sorting is “easy”: sieve. Here are some nuisance (like, if I want to rename folder/mailbox I need to edit script manually. BTW, it looks like that such thing could be done automagically, as language is very simple and find all references to mailboxes is not too hard task), but it works. But is here good solution for expiration? I have abut 50 folders (mailboxes) and rules are very different for them. They are mostly time-based (like "last 30 days"), but some folders are count-limited ("last 2000 messages") and some folders should have time limit but non-read messages could not be deleted at all. Ok, Thunderbird almost could do it (it doesn't have “don't remove unread messages” option), but I don't want to have any meaningful configuration in MUAs, as each of it could be non-active for long time. Only thing I could find about expiration in dovecot documentation is "doveadm expunge" and helper "Expire" plugin, but it looks like very low-level solution for admins, it could not be managed from client side without direct ssh access to server and it is, in general, very inconvenient. Is here any better solution, maybe, 3rd party one? - -- // Black Lion AKA Lev Serebryakov -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQJ8BAEBCgBmBQJUFf2BXxSAAAAAAC4AKGlzc3Vlci1mcHJAbm90YXRpb25zLm9w ZW5wZ3AuZmlmdGhob3JzZW1hbi5uZXRGOTZEMUNBMEI1RjQzMThCNjc0QjMzMEFF QUIwM0M1OEJGREM0NzhGAAoJEOqwPFi/3EePphIQAJUlYIFgXWBcWcrejcbOFgYf op+g35YF4wfwboPkgb/mKk46V3lcjmQImcHir2fci0SCsSSfARcU1a8y4iaeSkPU l949PaMYD8stfukfCbXjoY5pD5FIpj1Os7dDtgdoygp0tfsA4mDg1O0exZoduR9s q4NNPlsnlKOjX2KMOdcWI2AR8/xiFi4zvDTB/vibQPMy8kXVB8ld4Mk0BF1TUyOv 80KKOKzFDxQeLzvoEiNm6FDAqYGEYmpECUaFGXyKG1a7wslhEmEeShJUH5lsj3Oz niMxoO/KTEW0U9QucHQogFJzrcsKkJiOByjqQovWKgZziJll38lCN0O1murMmRBC bDLmN9t53JC7Ef88AbKsaFeULy/AxriohdGU6ePb8j/4W9KlERSJyvgxFkcMxHTg 9mSPiYAHaPr+Ycrzs9SOqhki5b6tI8Q39W/etRorb2us9FS1JE7ib4XLk5ufiUje XOLc4TACUh1qnd/5UUgcIuUrg/akSJgJLZoXg36LqUF/1OeMJHec4RMJresvewAZ RwseWHH/KpD7KxOWlO2Zw1ceHlVFDLWOO/4KWoy/XwZ66fQxEAkLO8ZVyeKMh5Nh dYL+yLQKZdgNWAjalK4lFmwz3u/9jNITwtP5GYLbYnP28EcbDfiN/w9oKGOI8fsD ulD+ca3vx29qdmGGYcKt =9+bG -----END PGP SIGNATURE-----

sieve: is it possible to filter ALL mailing lists (with header List-Id) to their folders with ONE rule?
by Lev Serebryakov 15 Sep '14

15 Sep '14

Hello, Dovecot. Is it possible to write one rule in sieve, which will: (1) Trigger on any message with "List-Id" header AND (2) Put this message to folder with name build from content of "List-Id" header, in such way, that message with List-Id List-Id: This is decription of list <list-name.host.org> will be put into folder "org.host.list-name" where "." is namespace separator (so, such folders will be shown as hierarchy in mail client)? I don't want to write ~50 rules by hands and add new ones from time to time. I'm speaking about dovecot/pigeonhole sieve implementation, of course. All examples on net shows only manual one-rule-per-list approach :( -- // Black Lion AKA Lev Serebryakov <lev(a)serebryakov.spb.ru>

Migration - Getting it right the first time.
by Dan Carroll 15 Sep '14

15 Sep '14

Hello All, I’m currently in the process of migrating a very old imap installation to a new server. I think I have everything in place now but I’ve not yet written the procedure on how to do it. The outline will be as follows: put MTA-OLD into store mode where it holds the incoming emails for an indefinite period. Copy all IMAP data across to the new server. Process the IMAP data, converting it from courier to dovecot. put MTA-OLD into forward mode, sending all mail to MTA-NEW Adjust MX records accordingly so MTA-OLD is no longer used. The “process” part is where I need to take some care. I am aware of the migration tool available for moving the data, but I’m not confidant that my courier databases are in a healthy state. Does anyone have any idea how I can verify that this is the case? I’m happy to do it either before, or after the migration to dovecot, but I’d probably prefer to do it beforehand on the old server. The biggest thing I am concerned about is losing the order of mail messages. It’s not always enough to trust the “received date” for sorting mail, I’d rather my imap clients trust the imap server to send them the correct order. A second question. Is there a possibility to make the MTA switch, and migrate the messages across in an orderly fashion at a later date? Again, I’d like to ensure that older migrated messages appear further down the “order” than new messages coming into the MTA. Lastly, thanks for an awesome piece of software. My limited experience so far has been refreshing! -Dan

Dovecot HA
by Hoggins! 13 Sep '14

13 Sep '14

Hello everyone, Following my previous message about replication (I'm still stuck), I was wondering in a more general way how to achieve high availability with Dovecot, and how to store the mail data. Do you have some thoughts about this ? Maybe one or two links leading to people who already have ideas or experience ? I don't host a big e-mail service, nor have a lot of clients connecting. I just need to ensure that data is always available, from the storage to the actual service. Thanks in advance.

charset-specific searches, and continuation lines
by Eric Abrahamsen 12 Sep '14

12 Sep '14

Hi there, I'm looking into improving IMAP search support for the Gnus Emacs mail client, and trying to add the ability to search non-ascii characters. So far as I know, I start this invocation with something like: . UID SEARCH CHARSET UTF-8 TEXT {NNN} Where NNN is the number of bytes in my search string. Dovecot then responds with: + OK So... what do I do then? I don't actually know what the next statement is, to provide the actual search string itself. Googling has proved unhelpful, as most of the examples online don't actually show this "+ OK" response. Can someone just briefly outline what's meant to happen next? I've tried including the search string immediately after the byte-size, separated by various combinations of \n\r, but that always gives me a "Missing LF after literal size" error. I'm using the Archlinux dovecot package, which reports version 2.2.13-1. Thanks! Eric

Problem with virtual folders

I copied the configuration from this server. The only three differences between the two servers are: - Server version is different. - The prefix of the default namespace on the new server is "prefix = INBOX/" and not "prefix =" - Mail storage and index files are seperated in different folders on the new server. Here are the relveant namespace configuraiton from the server where it ist working fine: ... namespace { list = children location = mdbox:/home/vmail/%%d/%%n prefix = shared/%%u/ separator = / subscriptions = no type = shared } namespace { hidden = no inbox = no list = children location = virtual:/home/virtual:INDEX=~/virtual prefix = [rolmail]/ separator = / subscriptions = yes type = private } namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Items" { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = separator = / type = private } ... Have you any hint for me how I can fix my problem. Thanks and regards Urban Loesch

minimal configuration for lucene fts
by Eric Abrahamsen 11 Sep '14

11 Sep '14

Hi, I'm using dovecot (version 2.2.13 on archlinux) in the simplest, no-brainer way possible. It sits between mbsync, which I use to fetch mail from servers, and Gnus, my MUA. Both mbsync and Gnus connect to dovecot with an invocation like this: /usr/lib/dovecot/imap -o mail_location=maildir:$HOME/.mail/ea/ I have three different mail accounts, all that changes is the final directory on the mail_location path above. I haven't touched anything else: there's no running daemon, no configuration, no user database, no PAM, no nothing. Now I'm trying to set up text searching via lucene, but all the examples I've seen online assume a full running daemon and user accounts. I tried to fake it by running: doveadm index -u eric@localhost -q INBOX -o mail_location-maildir:/home/eric/.mail/ea but it was clearly expecting a user database. Is there any way to create text indexes for my three different accounts, in their respective directories, without fully setting up a running dovecot? I'll do that if I have to, but my current setup works great, and is very simple, and I'd like to keep it simple if I can. Thanks! Eric

Dovecot can't read mail, creates duplicate directories

CentOS 6.5, dovecot 2.0.9-7 I used http://www.linuxmail.info/postfix-dovecot-ldap-centos-5/ to configure LDAP authentication for postfix and dovecot.

Just a wild-ass guess, but shouldn't "master_user=%u" be something like "master_user=muser" where "muser" is the master user as defined in your master password file?

outlook 2013
by Bob Miller 10 Sep '14

10 Sep '14

I am trying really hard to wrap my head around why people insist on using this program... Where I have outlook 2013 users, I have had nothing but problems getting their mail to work with imap. my solution has been to set them up with pop, which works just like it always has. Or move them to a different program. recently, I have a customer who requires multiple machines, all using outlook 2013, to access the same email address, so pretty much have to use imap. if I set up just one of the machines with imap, it works more less as expected, with hiccups such as mail taking an hour or two or more to show up. But shortly after I connect a 2nd machine to the same account, one or both machines start to go wonky. Symptoms include deleted items returning, read messages becoming unread again, and duplicates being constantly created and deleted. The last I can confirm by watching in webmail and refreshing the inbox every few seconds; as mail shows up and deletes in outlook, so it does in webmail too. On my test machine connected to the same server, I have evolution, outlook and thunderbird all connecting to one account with no problems. Well, outlook hiccups, but it's not unusable. And I have other users on the system that share email accounts across a variety of other clients and platforms, including older versions of outlook. I have tried checking message rules, there are none; removing all folder subscriptions; running scanpst, which finds errors even before the account finishes syncing and ever time I run it after that; I have looked for viruses/malware; I have confirmed there is no forwarding or some trickery happening on the server; chkdsk and similar hardware checks all come up clean, the computers are only a couple of months old; I have got certs set up with SANs and the CA installed such that outlook does not error on the certificate; and I have tried just about every combination of settings that seem relevant. The one thing that does seem to work, at least for a few minutes or an hour or two, is deleting and recreating the accounts on one of the computers. But the problem inevitably returns in short order. Surely people have outlook 2013 connecting via imap to dovecot without problems; is there some special trick that google is hiding from me? -- Computerisms Bob Miller 867-334-7117 / 867-633-3760 http://computerisms.ca

Dovecot replication
by Hoggins! 10 Sep '14

10 Sep '14

Hello list, I'm trying to achieve very simple replication, but I'm not sure if I'm starting the good way. I have two Dovecot servers that use the same GlusterFS storage. Of course, the indexes get corrupted eventually, even if I apply an "NFS-like" configuration. So I'd like to synchronize my two servers with each other. I'm trying to follow this page : http://wiki2.dovecot.org/Replication, but I have to admit that it's not really self-explanatory. I got several errors, so I decided to start fresh, and that is why I'm not giving you any configuration, but I prefer asking if I have the prerequisites. The page states that my userdb should have "user listing", and that you can check it by issuing `doveadm user '*'`. But I don't know what it's supposed to produce, apart from my userlist (my userdb is the system passwd file). As my servers are located on the same private LAN, I decided I would not go with the SSH replication solution, but with the simple mutual TCP connection... Maybe this is a wrong start. Any help will be appreciated. Thanks in advance !

dovecot 2.2.13: LMTP delivery with multiple recipients incorrectly mixes users

Hi. I'm using exim that delivers email over LMTP to dovecot 2.2.13. I noticed that dovecot LMTP service is sometimes (reare but repeats) mixing users. Example below. There is one mail (msgid=<1ACE53B70631CA45B62348E4EE8757493731A59E@KRMXA41>) that is going to be delivered to multiple local recipients.

Replication problem
by Ve (HOME) 10 Sep '14

10 Sep '14

Hi, I'm using mdbox and replication. Due to configuration error synchronization was not able to be done last week. Since then the problem has been corrected but synchronisation for some mailbox always failed in I/O stalled timeout for 600 seconds. The link between the two servers is quite slow and multiple sync are done in parallel leading to congested link. I can't replicate with rsync as change in the mdbox has been done on the two servers to get back to a working state. What do you think could be done to resynchronized the two dovecot server. Another question is what is this timeout ? Timeout of communication i.e no data received during 600 seconds ( to me that looks unlikely ) or 600 seconds for doing the full sync or 600 seconds for one mail sync. Thanks for any help. Regards, Vincent

preserving flags for shared mailbox when migrating from cyrus to dovecot
by Jogi Hofmüller 10 Sep '14

10 Sep '14

Dear all, Despite all the progress we are making in our attempt to make the migration as smooth and transparent for our users there are still some important unsolved issues. One thing that I can't figure out is how to preserve a user's flags that s/he has for mail in a shared mailbox. So far we tried 'doveadm backup -R' as well as the cyrus2dovecot script from here [1]. Both work well for individual mailboxes but do not migrate subscriptions for shared mailboxes and -- more importantly -- flags for mail in a shared mailbox. Reconstructing subscriptions is quite easy but I have no clue on how to reconstruct a user's flags. Any hint is greatly appreciated!
