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/ * * * ***********************************************************************

Hello, I'm trying to use my server running dovecot to receive via imap a backup of my gmail account, messages. I'm getting an error from imap.gmail.com that it does support plain authentication but that it failed to download messages. If anyone has this working please let me know what you had to do. Thanks.

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
