[Dovecot] plugin development guide for non-FS backing store
by Chang Song 21 Sep '09

21 Sep '09

Hi, folks. I was wondering if anyone has some sort of guide or reference on plugin development. We are trying to develop a non-filesystem backing store. So basically we do not store mailboxes for users in local filesystem. We do RPC call to fetch from fileservers. Thank you in advance. Chang

[Dovecot] Override quota rules based on mail's content
by Andreas Calvo Gómez 21 Sep '09

21 Sep '09

Hi, I've a mail server with Postfix and Dovecot, using a LDAP backend to get the users. I've also configure quota rules, and I'm able to get the quota from LDAP. But I need the mails that come from the local domain to bypass the quota rule and be delivered to the users' inbox. Is there any way to do that? Information required by Dovecot's mailing list rules: +++ dovecot.conf +++ # 1.1.11: /etc/dovecot/dovecot.conf # OS: Linux 2.6.28-15-server x86_64 Ubuntu 9.04 ext4 log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_user: postfix valid_chroot_dirs: /var/spool/dovecot first_valid_uid: 1000 first_valid_gid: 512 mail_privileged_group: mail mail_location: maildir:/var/spool/dovecot/%n/ mail_plugins: quota imap_quota imap_client_workarounds: delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep auth default: mechanisms: plain login default_realm: esci.es username_format: %Lu passdb: driver: pam passdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf userdb: driver: prefetch userdb: driver: passwd userdb: driver: ldap args: /etc/dovecot/dovecot-ldap-userdb.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: mail group: mail plugin: quota: maildir:User quota quota_rule: *:storage=50M quota_rule2: Trash:ignore +++ dovecot-ldap.conf +++ hosts = ldap.esci.es auth_bind = yes ldap_version = 3 base = ou=Users, dc=esci, dc=es scope = subtree user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid,mailQuota=quota_rule=*:storage=%$M user_filter = (&(objectClass=posixAccount)(|(mail=%u)(uid=%u)(uid=%n))) pass_attrs = uid=user,userPassword=password,\ homeDirectory=userdb_home,uidNumber=userdb_uid,gidNumber=userdb_gid,mailQuota=userdb_quota_rule=*:storage=%$M pass_filter = (&(objectClass=posixAccount)(|(mail=%u)(uid=%u))) default_pass_scheme = SSHA Thanks. --------------------- Andreas Calvo Gómez <andreas.calvo(a)admi.esci.es> Dept.

[Dovecot] Automatic fd limit changing
by Timo Sirainen 21 Sep '09

21 Sep '09

I just realized that Dovecot should probably be doing something different with how it handles fd limits. The way it currently works is: 1. It checks some settings and warns at startup if fd limit is lower than what master process might need. 2. For login processes it calculates how many fds are needed and then either increases or decreases it. So it's automatically and silently increasing fd limit for some processes, but not for others. Should it just automatically increase the limits to all processes when necessary, or never increase and just warn that the limit is too low?

[Dovecot] Sieve not fast enough after upgrade?
by Nikolay Shopik 21 Sep '09

21 Sep '09

I've upgraded mine Dovecot 1.0.15 to 1.2.4 also moved to new Sieve. I have simple sieve rule: if header :contains "Delivered-To" ["bcc(a)bcc.inblock.ru"] { setflag "\\Seen"; } It basically mark my own messages which are saved to Sent folder. When I was on 1.0.15 I never seen unread count in Thunderbird, but suddenly after upgrade I seen unread message in Sent folder just after I've sent message. If I open Sent folder it already marked as read. Me wonder if this is actually Dovecot much faster delivers and reports to MUA there is new unread message or Sieve not perform fast enough?

[Dovecot] Dovecot Sieve Vacation Messages
by Steven Murphy 20 Sep '09

20 Sep '09

I'm using a Postfix, Dovecot, MySQL setup with virtual domains. I have mail being delivered through Dovecot LDA working 100%. I'm trying to use sieve to handle vacation messages but dovecot is not reading the .dovecot.sieve file in the users maildir. I have a hunch it has to do with my dovecot-sql query but have had no success with what I found in the forums from Googling. Any help would be greatly appreciated. I've included my configs below: # 1.2.4: /etc/dovecot/dovecot.conf # OS: Linux 2.6.29-gentoo-r5 x86_64 Gentoo Base System release 1.12.11.1 ext3 protocols: imap imaps pop3 pop3s listen: *, [::] ssl_cert_file: /etc/ssl/dovecot/server.pem ssl_key_file: /etc/ssl/dovecot/server.key disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login login_user: postfix mail_privileged_group: vmail mail_location: maildir:/home/vmail/%d/%n/.maildir mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugin_dir(default): /usr/lib64/dovecot/imap mail_plugin_dir(imap): /usr/lib64/dovecot/imap mail_plugin_dir(pop3): /usr/lib64/dovecot/pop3 imap_client_workarounds(default): outlook-idle delay-newmail imap_client_workarounds(imap): outlook-idle delay-newmail imap_client_workarounds(pop3): pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh lda: postmaster_address: postmaster(a)example.com mail_plugins: quota sieve auth default: mechanisms: plain login user: vmail passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: prefetch userdb: driver: sql args: /etc/dovecot/dovecot-sql.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: vmail group: vmail plugin: quota: maildir sieve: /home/vmail/%d/%n/.dovecot.sieve ################################################## #dovecot-sql.conf driver = mysql connect = host=localhost dbname=mail user=mailuser password=[password] default_pass_scheme = PLAIN-MD5 user_query = SELECT homedir AS home, sieve, CONCAT('*:storage=', quota) AS quota_rule FROM users WHERE username = '%u' password_query = SELECT crypt AS password, CONCAT('*:storage=', quota) AS userdb_quota_rule FROM users WHERE username = '%u'

[Dovecot] simple feature request: IMAP logged out message
by Leonardo Rodrigues 18 Sep '09

18 Sep '09

i'd like to make a simple feature request on dovecot .... i'm using v1.2.4 (latest one) and IMAP logout message, by default is: Sep 18 14:26:27 correio dovecot: IMAP(user(a)domain.com): Disconnected: Logged out bytes=384/932222 the message can be a little customized with: # IMAP logout format string: # %i - total number of bytes read from client # %o - total number of bytes sent to client imap_logout_format = bytes=%i/%o The remote IP address, the IP which the user is coming from, can only be seen on the login message: Sep 14 09:09:12 correio dovecot: imap-login: Login: user=<user(a)domain.com>, method=PLAIN, rip=187.6.xx.xx, lip=200.140.yy.yy the feature request is that the remote IP address could be added on the Logout message too, that would make much easier to watch connections from some specific user and from some specific ip address, regarding traffic of the connection. For example, something like: Sep 18 14:26:27 correio dovecot: IMAP(user(a)domain.com): Disconnected: Logged out bytes=384/932222, rip=187.6.xx.xx, lip=200.140.yy.yy -- Atenciosamente / Sincerily, Leonardo Rodrigues Solutti Tecnologia http://www.solutti.com.br Minha armadilha de SPAM, NÃO mandem email gertrudes(a)solutti.com.br My SPAMTRAP, do not email it

[Dovecot] IMAP clients suddenly redownload folder headers
by Brent Bloxam 18 Sep '09

18 Sep '09

We had an issue today with IMAP clients (Thunderbird, Outlook) having to redownload headers for folders. This issue was eerily close to a MySQL database structure change that shouldn't have affected any related queries, however we did notice an event of user CPU % not being reported via SNMP around the same time for the server. There are no entries in our dovecot error log around the outage. We're running Dovecot 1.1.13 with MySQL being used for user and password queries, and Maildir for storage on a fibre channel SAN. However, it is possible for some stores to be on an NFS mount (supporting legacy during migration), which is why there is the nfs options in the below config. I'm wondering if someone could shed light on what could cause this to occur. I imagine it's related to the index cache's, but the lack of any mention in the error logs has me puzzled. Output of dovecot -n: # 1.1.13: /usr/local/etc/dovecot.conf # OS: FreeBSD 7.0-RELEASE i386 base_dir: /var/run/dovecot log_path: /var/log/dovecot-error.log info_log_path: /var/log/dovecot-info.log protocols: imap pop3 ssl_disable: yes disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login mail_max_userip_connections: 100 first_valid_uid: 89 mail_privileged_group: 89 mail_uid: 89 mail_gid: 89 mail_location: maildir:~/Maildir mail_debug: yes mmap_disable: yes mail_nfs_storage: yes mail_nfs_index: yes lock_method: dotlock mail_executable(default): /usr/local/libexec/dovecot/rawlog /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/rawlog /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 pop3_uidl_format(default): %08Xu%08Xv pop3_uidl_format(imap): %08Xu%08Xv pop3_uidl_format(pop3): %f namespace: type: private separator: . prefix: INBOX. inbox: yes list: yes subscriptions: yes auth default: mechanisms: plain apop cache_size: 10240 cache_negative_ttl: 30 username_format: %Lu passdb: driver: sql args: /usr/local/etc/dovecot-sql.conf userdb: driver: sql args: /usr/local/etc/dovecot-sql.conf
