[Dovecot] virtual mailboxes folder structure
by Marco Cusano 08 Jan '14

08 Jan '14

Hi, I am trying to find a way to list my virtual mailboxes hiding the namespace prefix into my imap client. Fore example now my “All” mailbox is listed under virtual/ as: Inbox Sent Drafts Spam Trash - virtual All I would like to list as this: Inbox Sent Drafts Spam Trash All This is my 10-mail.conf: http://pastebin.com/DumEbbmy and this is my 15-mailboxes.conf: http://pastebin.com/QFzWGzyC I thought that the list = children paramenter would do but it did not. Thank you

Re: [Dovecot] BUG report: doveadm HEADER <field> <pattern> when concatenating with another Search key

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. Maybe also relevant, as mail format I'm using sdbox (on a larger user base of 40.000 people). -- (relevant part) of dovecot -n # 2.2.5.5 (e5350245ad9b): /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-358.23.2.el6.x86_64 x86_64 Red Hat Enterprise Linux Server release 6.4 (Santiago) nfs auth_cache_size = 100 M auth_cache_ttl = 10 mins auth_master_user_separator = * auth_mechanisms = plain login auth_username_format = %Ln auth_verbose = yes disable_plaintext_auth = no import_environment = TZ DEBUG_OUTOFMEM DOVECOT_HOSTDOMAIN listen = * lock_method = dotlock mail_fsync = always mail_home = /mnt/nfs/vmails/%u mail_location = sdbox:/mnt/nfs/vmails/%u/mail:ALT=/mnt/archivnfs/vmails/%u/mail mail_plugins = " quota fts fts_lucene" mail_privileged_group = mail managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave mmap_disable = yes service imap-login { process_limit = 200 process_min_avail = 8 service_count = 0 vsz_limit = 512 M } service imap { client_limit = 1 process_limit = 10000 } service pop3-login { process_limit = 200 process_min_avail = 8 } service pop3 { process_limit = 10000 } verbose_proctitle = yes protocol lda { mail_plugins = " quota fts fts_lucene sieve" } protocol imap { imap_client_workarounds = tb-extra-mailbox-sep mail_max_userip_connections = 50 mail_plugins = " quota fts fts_lucene imap_quota" } _________________________________________________________________ Send and receive anonymous emails to your inbox with InboxAlias. http://www.inboxalias.com

[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] inotify max_user instances
by Charles Marcus 07 Jan '14

07 Jan '14

Hello, Timo, last year when you remoted into our server and performed the migration from courier-imap, we ran into this issue, and you solved it by doing: echo 1024 > /proc/sys/fs/inotify/max_user_instances Then you said you were going to solve this permanently by changing the init script... Here is what you said (this is from the skype chat): [2012-06-04 10:40:43 AM] timosirainen: probably put to dovecot init script or something I guess I could manually modify my init script, but I'm clueless as to where.how.
