I tried using logical conjections of header searches and it works with my installation of dovecot, so either it's a bug introduced later than 2.1.16, or perhaps it from the different search engine you use (I use the default that comes with dovecot -- squat?).

[Dovecot] Disallow certain characters in foldernames?
by Charles Marcus 08 Jan '14

08 Jan '14

Is there a way to do this in dovecot? Similar to how you can When using Maildir and Thunderbird, if a user tries to a create folder named "test.1" or "test/1", dovecot will happily create a folder called "test", with a subfolder called "1". Worse, the top level folder "test" is greyed out, which is how Thunderbird displays a folder that can contain only other folders, not both folders and files. I want to disallow this. Obviously I'd prefer if Thunderbird would display a meaningful error, but most likely dovecot cannot control that. I don't really care if the user just gets some kind of weird generic error or not, I'd just prefer to prevent dovecot from creating the problematic folders, and explain the problem to the user if/when they call about it (after NOT reading my carefully crafted documentation explaining the illegal characters that cannot be used in foldernames). -- Best regards, Charles

[Dovecot] acl, shared folders
by Infoomatic 08 Jan '14

08 Jan '14

Hi list, After spending quite some time to figure out how users can share folders I now hope someone of you could help me out. I am quite sure its just a stupid mistake/misunderstanding ... I am using Ubuntu 12.04 LTS with the shipped dovecot 2.0.19 When I login via telnet as user1 I get the following: 1 create folder1 1 OK Create completed. 2 setacl folder1 user2 rli 2 OK Setacl complete. 3 getacl folder1 * ACL "folder1" "user2" ilr "user1" lrwstipekxacd 3 OK Getacl completed. This seems fine. However, there is nothing listed in the account of user2. I think the mistake is in the namespace configuration of "location" or "prefix" Please help!

[Dovecot] LMTP with virtual and system users
by Philipp Kolmann 08 Jan '14

08 Jan '14

Hi, I have a mailsystem where i have some local users with shell access and full home dirs which receive mail and also several SQL virtual users only for mail. With the virtual users, everything works fine. Mail is delivered via LMTP and also sieve works :) The SQL Lookup knows what to do with username(a)domain.com The problem is the system user. If exim delivers the mail to the lmtp socket, the LMTPd can't find username(a)local.host I would be able to specify the global auth_username_format=%n but then my SQL queries break and I like the possibility to have xx(a)domain1.com and xx(a)domain2.com routed to two different accounts. As I have seen in the source, I can't specify username_format=%n in the passdb { driver = pam } backend. Do you have any suggestion how to solve this issue? thanks Philipp

[Dovecot] Question re: filesystem permissions
by Charles Marcus 08 Jan '14

08 Jan '14

Hi all, I want to make sure the filesystems are correct/optimal and secure as possible. This is a virtual hosting setup only (no system users), and dovecot is currently running in high performance mode (I'm thinking I want to change that too, so wondering if that would affect the permissions)... /var/vmail (and everything under it) is owned by vmail:vmail. Current permissions are: /var/vmail 755 /var/vmail/example1.com 777 /var/vmail/example2.com 777 /var/vmail/example1.com/user1 755 (all other user home dirs are the same) /var/vmail/example1.com/user1/Maildir 700 (all other user Maildirs and all subdirs are the same) All files are 600, with the exception of the dovecot-uidvalidity.blahblah files, which are 444 So... is this right? Anything need to be changed? Thanks, -- Best regards, Charles

[Dovecot] virtual mailboxes folder structure

Hi, I am trying to find a way to list my virtual mailboxes hiding the namespace prefix into my imap client.

Hey Joseph! Thanks for testing. > I couldn't recreate this with 2.1.16. Also, my version of "doveadm > search" does not accept missing header patterns. Is this corroborated > by dumping out the header with this same search query? > > doveadm fetch -u exampleuser hdr SUBJECT Silvester \ > HEADER Return-Path someuser at example.com Yes, it's same phenomenon when dumping with fetch. Of course you can only test this properly when you really have some mails with corresponding existing Header fields. (You can also try out other HEADER fields, like Reply-To, References, X-Spam-Score or whatever - just look at some mail headers of your mails and try it with existing fields.) So E.g. When doing doveadm fetch -u exampleuser hdr SUBJECT Silvester HEADER Return-Path someuser(a)example.com it initially outputs 13 headers (same as when using with SUBJECT Silvester only) , when piping it to "grep -i 'Return-Path'" it even found only 3 out of 13 headers containing a Return-Path at all, 2 of them different than someuser(a)example.com - so SAME behaviour as with search.

[Dovecot] how to separate virtual delivery and authentication?
by Mihai Badici 08 Jan '14

08 Jan '14

I have a "pure ldap" setting with postfix and dovecot. When using dovecot delivery, the recipient is checked via ldap. The same ldap query is used when authenticate. So, if I want to authenticate with the uid , I can't use a filter like uid=%u because the delivery will fail. I don't want to use %nor something else because I could use multiple e-mail addresses on a single account. I actually use a filter like ( mail=%u)|(uid=%u) but I think for more complex situations should be better to have two separate filters, one for authentication and the other for the delivery. What is your oppinion? -- Mihai Bădici http://mihai.badici.ro

[Dovecot] Dovecot can't find CLucene's libstemmer on FreeBSD
by interfaSys sàrl 08 Jan '14

08 Jan '14

Hello, A set of patches was created by Lawrence Chen for the Dovecot2 port so that it could recognise and use libstemmer and libexttextcat. They can't be used as is as he's replacing statements with something that works only on FreeBSD, but I think it would be a good idea to try and include some of his fixes. http://www.freebsd.org/cgi/query-pr.cgi?pr=ports/175813 Cheers, Olivier

Re: [Dovecot] using OR in doveadm search query

I guess > because now the query has become a mailbox name that does not exist. ( I > am using dovecot 2.2.9) Each search token ought to be a command line argument to doveadm, so if you're looking for all message with the string "a" or "b" in the subject in mailboxes shared/*, then this should be the correct syntax, with all arguments sufficiently escaped from shell interpretation: doveadm search mailbox shared/\* $ SUBJECT a OR SUBJECT b $ (Delete "OR" if both strings must be in the subject: expressions are implicitly AND'd if not OR'd. In fact, you can also remove the parenthesis since precedence doesn't matter anymore.) You can check the search query by fetching some values using the same query: doveadm fetch 'mailbox hdr' mailbox shared/\* $ SUBJECT a OR SUBJECT b $ Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] Mailbox autocreate feature cannot create folders
by interfaSys sàrl 08 Jan '14

08 Jan '14

Hello, The "new" way of creating default mailboxes doesn't work for us. There seems to be a permission problem. We get this in the logs: imap(testuser(a)domain.com): Error: nfs_flush_file_handle_cache_dir: rmdir(/var/mail) failed: Device busy That error message has nothing to do with NFS (not used) or /var/mail and appears every time an app is requesting a list of folders via IMAP and only if we enable the autocreate feature. We're using mdbox, emails are delivered via LDA and the folder permissions look like this: # la /home/user/imap/domain.com/testuser/mdbox/mailboxes/ total 5 drwx------ 3 user mail 3B Jan 5 19:33 INBOX drwx------ 3 user mail 3B Jan 5 19:33 . drwx------ 4 user mail 8B Jan 7 02:43 .. The mailbox definitions used come straight from the wiki: http://wiki2.dovecot.org/MailboxSettings I've enabled debugging, but there is no mention of the mailboxes to create: Debug: dict quota... Debug: Namespace : type=private, prefix=, sep=/, inbox=yes, hidden=no, list=yes, subscriptions=yes location=mdbox:~/mdbox Debug: fs:... Debug: acl:... ... Here is what works: - Autocreate plugin - Creating folders via various clients So, it seems Dovecot can create folders, just not using that feature. If that's not a bug, would there be a way to make it work without altering permissions? Cheers, Olivier

[Dovecot] need assistance migrating between apple servers

I am attempting to move imap folders from an Apple Snow Leopard server to a new Apple Mavericks server. Dovecot --version is not working , but I believe the old server is running dovecot 1.1.2 and can confirm the new one is running 2.2.x. I have tried taring and moving folders, but have not been able to get the transfered messages and folders to show up in user accounts (new messages show up fine). I have attempted to recreate index files, but that has not worked either. The last attempt I made to migrate was to use dsync, but it does not exist on the old server and I do not see a way to install it. What method would work best to migrate or move files and folders from the old server and get them to show up for clients on using the new server? -- Raymond Norton LCTN 952.955.7766 Sent from My Desktop

Hi, we are running a 4 host setup which each hosts a director+mailbox which is mounted via NFSv4 from a DRBD cluster. * Dovecot upstream release 2.1.16 * Doveadm batch subcommand fix - http://hg.dovecot.org/dovecot-2.1/raw-rev/850b5d8bbcc9 * Pigeonhole release 0.3.4 Now we would like to remove duplicate Mails using the vnd.dovecot.duplicate extension using a SIEVE script like this: require ["vnd.dovecot.duplicate", "fileinto", "mailbox", "regex", "vacation", "variables"]; if duplicate { fileinto :create "Trash"; } But as soon as we start delivering duplicate mails, we're sometimes getting locking errors from the mailbox (which is responsible for the user) according to the director: Dec 27 16:36:30 10.129.3.213 dovecot: lmtp(27975, user001(a)example.org) Error: Creating lock file for /mail/dovecot/example.org/user001/.dovecot.lda-dupes timed out in 20 secs Dec 27 16:36:33 10.129.3.213 dovecot: lmtp(27987, user001(a)example.org) Error: Creating lock file for /mail/dovecot/example.org/user001/.dovecot.lda-dupes timed out in 20 secs Dec 27 16:36:35 10.129.3.213 dovecot: lmtp(27994, user001(a)example.org) Error: Creating lock file for /mail/dovecot/example.org/user001/.dovecot.lda-dupes timed out in 20 secs Dec 27 16:36:36 10.129.3.213 dovecot: lmtp(28011, user001(a)example.org) Error: Creating lock file for /mail/dovecot/example.org/user001/.dovecot.lda-dupes timed out in 20 secs Dec 27 16:36:36 10.129.3.213 dovecot: lmtp(28013, user001(a)example.org) Error: Creating lock file for /mail/dovecot/example.org/user001/.dovecot.lda-dupes timed out in 20 secs Dec 27 16:36:38 10.129.3.213 dovecot: lmtp(28017, user001(a)example.org) Error: Creating lock file for /mail/dovecot/example.org/user001/.dovecot.lda-dupes timed out in 20 secs Dec 27 16:36:39 10.129.3.213 dovecot: lmtp(28025, user001(a)example.org) Error: Creating lock file for /mail/dovecot/example.org/user001/.dovecot.lda-dupes timed out in 20 secs Dec 27 16:36:42 10.129.3.213 dovecot: lmtp(28037, user001(a)example.org) Error: Creating lock file for /mail/dovecot/example.org/user001/.dovecot.lda-dupes timed out in 20 secs Dec 27 16:36:43 10.129.3.213 dovecot: lmtp(27973, user001(a)example.org) Error: Creating lock file for /mail/dovecot/example.org/user001/.dovecot.lda-dupes timed out in 20 secs Configs and Error log is attached. Any idea how to mitigate these locking issues? Regards Daniel

[Dovecot] disable_plaintext_auth = yes not showing in doveconf -n output?
by Charles Marcus 04 Jan '14

I have it set, but it doesn't show up. However, I noticed that it does show as enabled by default in doveconf -a output. Is this why it doesn't show up in doveconf -n output? -- Best regards, Charles

[Dovecot] RFE: IMAP LIST Extension for Special-Use Mailboxes
by Patrick Ben Koetter 03 Jan '14

03 Jan '14

Timo, would you consider adding support for "IMAP LIST Extension for Special-Use Mailboxes" <http://www.rfc-editor.org/rfc/rfc6154.txt> any time near in the future? I would really love to get rid of all those folders created by all those different mail clients just because they can't agree to use the same folder for special purpose. Obviously clients need to support it too. Having Dovecot support it certainly would make them adopt the standard sooner. p@rick -- state of mind Digitale Kommunikation http://www.state-of-mind.de Franziskanerstraße 15 Telefon +49 89 3090 4664 81669 München Telefax +49 89 3090 4666 Amtsgericht München Partnerschaftsregister PR 563

[Dovecot] Allow both SSL/993 and STARTTLS/143 connections (secure only)
by Charles Marcus 03 Jan '14

03 Jan '14

Hi all, Ok, up until now, I've only always allowed IMAPS connections to dovecot on port 993. I want to also start allowing clients to user port143+STARTTLS, but I walso want to make sure both ports are locked down to ONLY allow secure connections. So... is disable_plaintext_auth = yes in the main config enough to accomplish this? http://wiki2.dovecot.org/SSL/DovecotConfiguration says: There are a couple of different ways to specify when SSL/TLS is required: * disable_plaintext_auth=yes allows plaintext authentication <http://wiki2.dovecot.org/Authentication/Mechanisms> only when SSL/TLS is used first. * ssl = required requires SSL/TLS also for non-plaintext authentication <http://wiki2.dovecot.org/Authentication/Mechanisms>. * If you have only plaintext mechanisms enabled (auth { mechanisms = plain login } ), you can use either (or both) of the above settings. They behave exactly the same way then and the comments in 10-auth.conf say: # Disable LOGIN command and all other plaintext authentications unless # SSL/TLS is used (LOGINDISABLED capability). Note that if the remote IP # matches the local IP (ie. you're connecting from the same computer), the # connection is considered secure and plaintext authentication is allowed. # See also ssl=required setting. #disable_plaintext_auth = yes These seem to be saying that all I need to do is set either or both (ssl-required and/or disable_plaintext_auth=yes). I'm looking for the simplest, and don't like redundant/unnecessary settings, so... which is the best/preferred way? And what is the difference between ssl=required and disable_plaintext_auth=yes? Thanks, -- Best regards, */Charles/***
