[Dovecot] A common, read-only IMAP INBOX for all accounts
by Gus 19 Jun '13

19 Jun '13

Hi, since I had no luck finding people available on IRC, I hope someone here can provide me with some answers to, hopefully, 2 simple questions (and have the solution recorded in the archives for everyone with the same need). A little background, as the subject says it - I want to have a single INBOX shared among all the accounts on my system, where only one account would have writing rights, and all the rest would only be able to read the messages. Note this is different than providing a shared mailbox in addition to an INBOX - I actually want the shared INBOX to be the one and only folder that users can see and read as they will not be receiving any personal mails on this system. Naturally, I would also want that each account keeps track of read/unread messages independently of others. So, this is what I came up with (showing the relevant part of configuration only): # Per-user mail root and private/shared INBOX namespace userdb { driver = static args = uid=vmail gid=vmail home=/var/vmail/users/%u } namespace { type = private separator = / prefix = location = maildir:/var/vmail/public:INDEX=~/public inbox = yes } # The ACL contents of /var/vmail/public/dovecot-acl user=admin lrwstipekx anyone lrs Now, this actually results in exactly what I want (apart from a problem I'll describe below), but I'm not sure if it's the right way to do it. So the questions: 1. I have doubts that this solution could cause problems with dot file locking or dovecot data files corruption in the /var/vmail/public mailbox/directory when multiple users access the box simultaneously (and this could be thousands of users in production). Is this a valid concern and have I gone completely wrong with this solution, or there should be no problem with locking and I can keep it this way? If this is not the way to do it, can someone advise on the proper configuration that would achieve the same result, if it's possible at all (or what are the alternatives if it can't be done). 2. For testing purposes, I used a perl script (using the Maildir::Lite module) to create a test message in this mailbox (it gets stored in the new/ subdirectory, as I suppose it should). Now this message shows up as "unread" for all accounts, however when I read it in an IMAP client and then refresh the mailbox, it shows up as unread again. Per-user INDEX directory is writable and I see some files created there by dovecot, so shouldn't they contain the \Seen flags that indicate the message has been read? Is this maybe a client problem and how can I check that dovecot actually saves the flag correctly? The dovecot version I'm using is 2.0.9 (from the CentOS 6.x repositories). Thanks in advance and kind regards, Tin

[Dovecot] dovecot creating unknown users
by Yann Shukor 19 Jun '13

19 Jun '13

Hi We recently installed a dovecot postfix roundcube debian wheezy serverIt is now in production and we are feeling our way as we progressivelyadd new users to this local server. I noticed that dovecot is creating user directory structures for unknown users withinour domain in /var/vmail, even though we have setup a static users.conf db file. I tried omiting the "allow_all_users=yes" parameter but that doesn't seem to be linked to this issue Sorry if this has been asked a number of times already Is there an easy way to search the archives of this mailinglist ? Thanks yann # 2.2.2 (45399357008a): /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-4-686-pae i686 Debian 7.0 ext4 auth_debug = yes auth_mechanisms = plain login auth_socket_path = /var/run/dovecot/auth-userdb auth_verbose = yes disable_plaintext_auth = no first_valid_gid = 5000 first_valid_uid = 5000 hostname = holimail.holinice.com last_valid_gid = 5000 last_valid_uid = 5000 listen = * mail_debug = yes mail_gid = vmail mail_location = maildir:/var/vmail/%d/%n/Maildir mail_privileged_group = mail 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 namespace inbox { inbox = yes location = maildir:/var/vmail/%d/%n/Maildir mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = subscriptions = yes } passdb { args = scheme=CRAM-MD5 /etc/dovecot/users.conf driver = passwd-file } passdb { driver = pam } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } postmaster_address = azurtem(a)holinice.com protocols = " imap sieve pop3" service auth-worker { user = $default_internal_user } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } unix_listener auth-userdb { group = vmail mode = 0600 user = vmail } } service imap-login { group = dovecot inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } } service imap { process_limit = 1024 } service pop3-login { inet_listener pop3 { port = 110 } inet_listener pop3s { port = 995 ssl = yes } } service pop3 { process_limit = 1024 } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = uid=5000 gid=5000 home=/var/vmail/%d/%n allow_all_users=yes driver = static } userdb { driver = passwd } protocol lda { mail_plugins = " sieve" }

[Dovecot] v2.2.3 released
by Timo Sirainen 18 Jun '13

18 Jun '13

http://dovecot.org/releases/2.2/dovecot-2.2.3.tar.gz http://dovecot.org/releases/2.2/dovecot-2.2.3.tar.gz.sig This is a pretty important upgrade for v2.2 users, because of the IMAP ENVELOPE reply fix. * LDA/LMTP: If new mail delivery first fails with "temporary failure", tempfail the whole delivery instead of falling back to delivering the mail to INBOX. (Requires new Pigeonhole as well.) * doc/solr-schema.xml was updated to Solr v4.x format. Also the default analyzers were changed, hopefully for the better. Note that the schema can't be changed for existing Solr indexes without rebuilding everything. * Solr plugin does only soft commits from now on. You'll need a cronjob to send a hard commit command to it every few minutes. + Added %N modifier for variables as %H-like "new hash" + sdbox, mdbox: Support POP3 message order field (for migrations) + Added mailbox { driver } to specify a different mail storage format for the mailbox than generally used within the namespace. + Added initial lib-sasl library for client side SASL support. Currently supports only PLAIN, LOGIN and plugins. Used currently by IMAP and POP3 proxying when authenticating to the remote server. - IMAP: If subject contained only whitespace, Dovecot returned an ENVELOPE reply with a huge literal value, effectively causing the IMAP client to wait for more data forever. - IMAP: Various URLAUTH fixes. - imapc: Various bugfixes and improvements - pop3c: Various fixes to make it work in dsync (without imapc) - dsync: Fixes to syncing subscriptions. Fixes to syncing mailbox renames.

[Dovecot] Mailbox conversion/importing

I've been tasked with importing a large bunch of mbox folders (about 500) into an existing mdbox setup in Dovecot 2.1 As far as I can see, dsync "mirror" or "backup" are both inappropriate ways of doing this. Does anyone have any suggestions about how I could proceed? Thanks in advance

[Dovecot] Problem redirecting email using pigeonhole 0.4.0 (with patch)
by Andriy Syrovenko 18 Jun '13

18 Jun '13

Hello, Starting from the version 0.4.0 Pigeonhole adds "X-Sieve" and "X-Sieve-Redirected-From" headers ending them with CR+LF, and then copies the original message (including original headers) ending the lines with LF-only. This causes troubles at least if using Exim (I have not checked with other MTAs)- original message gets dropped, and only the new pigeonhole-generated headers are sent out. The attached file fixed the problem for me. --- dovecot-2.2-pigeonhole-0.4.0.orig/src/lib-sieve/cmd-redirect.c 2013-04-07 01:57:26.000000000 +0300 +++ dovecot-2.2-pigeonhole-0.4.0/src/lib-sieve/cmd-redirect.c 2013-06-05 03:22:53.000000000 +0300 @@ -344,9 +344,9 @@ string_t *hdr = t_str_new(256); /* Prepend sieve headers (should not affect signatures) */ - rfc2822_header_write(hdr, "X-Sieve", SIEVE_IMPLEMENTATION); + rfc2822_header_append(hdr, "X-Sieve", SIEVE_IMPLEMENTATION, FALSE, NULL); if ( recipient != NULL ) - rfc2822_header_write(hdr, "X-Sieve-Redirected-From", recipient); + rfc2822_header_append(hdr, "X-Sieve-Redirected-From", recipient, FALSE, NULL); o_stream_send(output, str_data(hdr), str_len(hdr)); } T_END; Best regards, Andrey.

[Dovecot] Dovecot 2.2.2: doveadm user doesn't honor -x option
by Axel Luttgens 17 Jun '13

17 Jun '13

Hello, 1. Considering a user_query similar to this one: SELECT ... FROM ... WHERE CASE '%s' WHEN 'lmtp' THEN ... and issuing following command: doveadm user -x service=lmtp someuser(a)example.com the log shows: SELECT ... FROM ... WHERE CASE 'doveadm' WHEN 'lmtp' THEN ... and the query of course fails. The same config with Dovecot 2.1.16 yields expected results. 2. This is more a question. Issuing above command first writes this to the log: prefetch(someuser(a)example.com): passdb didn't return userdb entries, trying the next userdb Is there really an attempt to make use of the prefetch database? If yes, under which circumstances could it succeed? TIA, Axel
