[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! Thanks! infoomatic # 2.0.19: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-45-generic x86_64 Ubuntu 12.04.3 LTS ext4 auth_username_format = %n disable_plaintext_auth = no mail_debug = yes mail_gid = vmail mail_home = /var/lib/vmail/home/%u mail_location = mdbox:/var/lib/vmail/mail/%u mail_plugins = " acl zlib fts fts_solr acl" mail_uid = vmail 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 imapflags mdbox_rotate_size = 64 M namespace { inbox = yes location = prefix = separator = / type = private } namespace { list = children location = mdbox:/var/lib/vmail/mail/%%n/mailboxes/shared/%n prefix = shared/%%n/ separator = / subscriptions = no type = shared } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { acl = vfile acl_shared_dict = file:/var/lib/vmail/shared-mailboxes fts = solr fts_solr = break-imap-search url=http://localhost:8080/solr/ sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_extensions = +imapflags zlib_save = bz2 zlib_save_level = 6 } protocols = " imap sieve pop3" service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { group = vmail user = vmail } } service managesieve-login { inet_listener sieve_deprecated { port = 2000 } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } protocol lda { mail_plugins = " sieve acl" } protocol imap { mail_plugins = " acl imap_acl" }

[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
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
by Joseph Tam 07 Jan '14

07 Jan '14

> > This works for me (at least with tcsh): > > > > $ doveadm search mailbox "shared/* OR (SUBJECT a) (SUBJECT b)" > doveadm does not complain anymore but it does not find anything. 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>
