[Dovecot] Problem with quota update in dovecot 1.2
by tower 16 Oct '12

16 Oct '12

Hi A have a problem with quota2 table, working under postfixadmin. When I login into imap server with thunderbird client everything works fine, quota is update when i receive a message, but when I move message to trash or any other folder value for messages field in table quota2 increases +1 instead decreases or have still this same value. Only if I close my imap client value descending -2. I wish to table quota2 will be updated immediately after any operation on inbox. Is there any mistake in my configuration? Thanks for any advice. ============================================================== dovecot -n print: # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-xen-686 i686 Debian 6.0.3 ext3 log_path: /var/log/dovecot/error.log info_log_path: /var/log/dovecot/info.log log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login first_valid_uid: 100 mail_privileged_group: Debian-exim mail_uid: 101 mail_gid: 103 mail_location: maildir:/var/mail/virtual/%d/%n/Maildir mail_cache_min_mail_count: 100 mail_debug: yes mbox_write_locks: fcntl dotlock mail_executable(default): /usr/lib/dovecot/rawlog /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/rawlog /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugins(default): autocreate quota imap_quota trash mail_plugins(imap): autocreate quota imap_quota trash mail_plugins(pop3): quota mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 imap_client_workarounds(default): tb-extra-mailbox-sep imap_client_workarounds(imap): tb-extra-mailbox-sep imap_client_workarounds(pop3): imap_id_log(default): * imap_id_log(imap): * imap_id_log(pop3): lda: postmaster_address: postmaster(a)mydomain.com mail_plugins: quota log_path: /var/log/dovecot/lda-errors.log info_log_path: /var/log/dovecot/deliver.log auth default: mechanisms: plain login verbose: yes debug: yes debug_passwords: yes passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: prefetch userdb: driver: sql args: /etc/dovecot/dovecot-sql.conf socket: type: listen master: path: /var/run/dovecot/auth-master mode: 384 user: Debian-exim plugin: autocreate: INBOX autocreate2: Sent autocreate3: Trash autocreate4: Drafts autocreate5: Junk autocreate6: Spam autosubscribe: INBOX autosubscribe2: Sent autosubscribe3: Trash autosubscribe4: Drafts autosubscribe5: Junk autosubscribe6: Spam quota: dict:user::proxy::quotadict quota_rule: Trash:storage=+20%% quota_rule2: Spam:ignore quota_rule3: Drafts:storage=+5%% quota_rule4: Sent:storage=+15%% quota_rule5: Junk:storage=+10%% quota_warning: storage=100%% quota-exceeded 100 %u quota_warning2: storage=95%% quota-warning 95 %u quota_warning3: storage=90%% quota-warning 90 %u quota_warning4: storage=85%% quota-warning 85 %u quota_warning5: storage=80%% quota-warning 80 %u quota_warning6: storage=75%% quota-warning 75 %u quota_warning7: storage=70%% quota-warning 70 %u quota_warning8: storage=65%% quota-warning 65 %u trash: /etc/dovecot/dovecot-trash.conf mail_log_events: delete undelete expunge copy mailbox_delete mailbox_rename flag_change append mail_log_group_events: no mail_log_fields: uid box msgid size subject from dict: quotadict: mysql:/etc/dovecot/dovecot-dict-quota.conf ============================================= cat /etc/dovecot/dovecot-sql.conf driver = mysql connect = host=localhost dbname=eximdb user=eximdbadm password=************* default_pass_scheme = PLAIN password_query = \ SELECT username as user, domain, password \ FROM mailbox WHERE username= '%u' AND active = 1 user_query = \ SELECT CONCAT('/var/mail/virtual/', maildir) AS home, 101 AS uid, 103 AS gid, concat('dict:storage=', CAST(ROUND(quota / 1024) AS CHAR), '::proxy::quotadict') AS quota, CONCAT('*:storage=', CAST(quota AS CHAR), 'B') AS quota_rule FROM mailbox WHERE username = '%u' AND active = '1' ============================================= cat /etc/dovecot/dovecot-dict-quota.conf connect = host=localhost dbname=eximdb user=eximdbadm password=********* map { pattern = priv/quota/storage table = quota2 username_field = username value_field = bytes } map { pattern = priv/quota/messages table = quota2 username_field = username value_field = messages } ============================================== cat /etc/dovecot/dovecot-trash.conf 1 Trash 2 Spam 3 Sent 4 Draft

[Dovecot] Plugin hooks in login process
by Simone Lazzaris 16 Oct '12

16 Oct '12

Hi all; I've setup dovecot (2.1.10) in a cluster configuration. We have two servers acting as frontend which authenticates users and proxy them to other two servers which handles the "real" work. Users credentials are on a mysql cluster; we have one master, in which read/write queries are processed, and many replicated slave, which process read-only queries. The frontend servers reads users credentials from the read-only mysql slaves. I'd like to execute a query once the client is verified to update the last login data. Right now, that query is executed on the backend servers, via a post-login service: protocols = imap service imap-postlogin { executable = script-login /usr/local/etc/dovecot/postlogin.sh unix_listener imap-postlogin { group = vchkpw mode = 0600 user = vpopmail } } service imap { executable = imap imap-postlogin process_limit = 2048 } Problem is, if I execute the update on the backend, I miss the information regarding the original IP, as I only see the IP of the proxies. I haven't been able to launch the postlogin service on the frontend, so I figured that I can try to write a plugin - that also seems to me the cleanest solution. Looking in the dovecot source code, I noticed that there aren't any hooks in the execution path used by the proxies; I am missing something ? I am the only one missing the presence of this hooks in the auth/proxy process ? I've also thought of a workaround for this problem. One way is to monitor the dovecot logs on the frontend and execute the update asyncronously. One other way is to query directly the main mysql server of the cluster and adjust the query making it call a stored procedure that updates the information in case of successful login. But I'd really prefer to create a plugin, that I'd be willing to share. I attach the configuration of the servers (front and back) generated via postfix -n. Thanks in advance for any help. -- Simone Lazzaris | Responsabile aree datacenter e VoIP Interactive Network srl | via Roggia Vignola 9, 24047 Treviglio (BG) Tel. 0363 1970352 | Fax 0363.1971971 | www.interactive.eu

[Dovecot] Dovecot deliver Segmentation fault when arrive the first message
by Alessio Cecchi 16 Oct '12

16 Oct '12

Hi, I have found this strange problem. I'm working with Debian 6, dovecot 2.1.9 and vpopmail-auth. LDA is configured and works fine but the problem is when the first message arrive "dovecot-lda" return a "Segmentation fault", the message is written to the user's Mailbox but the message remains, also, in the queue of qmail (deferral: Segmentation_fault/) and at the second attempt is delivered fine. If disable ACL (acl and imap_acl from mail_plugins) in dovecot.conf "Segmentation fault" go away. Moreover, without ACL at the first delivery folders like Sent, Drafts, Trash, Spam appear immediately. An example, new user: root@demo-vpop ~ # tree /home/vpopmail/domains/qboxdns.it/cecchi2/Maildir/ -a /home/vpopmail/domains/qboxdns.it/cecchi2/Maildir/ ├── cur ├── maildirsize ├── new └── tmp

[Dovecot] Search for substring in header?
by Dave Abrahams 16 Oct '12

16 Oct '12

Hi, According to the IMAP spec (http://tools.ietf.org/html/rfc2060#page-37) if I do a search for "TO isocpp.org" it should find all the messages whose To: field contains the string "isocpp.org", but dovecot is returning me an empty list. However, a search for "TO tm(a)isocpp.org" produces a long list of messages. What am I doing wrong?

[Dovecot] [BUG] Lucene plugin breaks header substring search
by Dave Abrahams 16 Oct '12

16 Oct '12

According to the IMAP spec if I do a search for "TO isocpp.org" it should find all the messages whose To: field contains the string "isocpp.org", but dovecot is returning me an empty list. However, a search for "TO tm(a)isocpp.org" produces a long list of messages. This behavior is present if I *even load* the lucene fts plugin.

Re: [Dovecot] per-user quotas
by David Mehler 16 Oct '12

16 Oct '12

Hello, Thanks for your replies so far. Still having issues with per-user quotas. To my Mysql virtual_users table I've added a column quota_kb and for a test user I've added in a value of 250000 going for a 250 megabyte quota. I've tried various sql queries they're returning empty sets not pulling out the information needed. Thanks. Dave.

[Dovecot] fts = squat solr
by Dave Abrahams 16 Oct '12

16 Oct '12

I don't know if this was supposed to have changed with dovecot2, but http://wiki.dovecot.org/Plugins/FTS shows fts = squat solr so, since I have the lucene plugin—"fts = lucene" works by itself—I tried fts = squat lucene but: $ doveadm index '*' doveadm(dave): Error: fts: Failed to initialize backend 'squat lucene': Unknown backend So, is that syntax obsolete, is the wiki wrong, or am I doing something wrong? -- Dave Abrahams BoostPro Computing Software Development Training http://www.boostpro.com Clang/LLVM/EDG Compilers C++ Boost

[Dovecot] POP UIDL
by simon.buongiorno＠gmail.com 16 Oct '12

16 Oct '12

Hi I run a small mail server with Dovecot and postfix. Several of the accounts are popped by an external email provide I use, mostly out habit and also for a bit of redundancy. I have no details on that external server except that it uses exim. Lately, it's been repopping mail from accounts (mail is left on the server so I can use IMAP) at fairly frequent, but undetermined, intervals. Before I take it to them, I want to be sure it's not an error on my side. How can I be sure Dovecot does not have a problem with the UIDL list causing this external server to repop the mail? For the record, I'm not inclined to think it's a Dovecot issue, but since that's the bit I can fix, I'd like to be sure. Cheers Simon
