[Dovecot] Client transaction logging in dovecot.
by Tan Shao Yi 05 Jan '07

05 Jan '07

Hi, Seasons greetings! :) May I know if it's possible to log the commands issued by clients in dovecot? For instance, RETR and DELE commands in POP3 and their equivalent in IMAP? I can't seem to be able to find the appropriate configuration key. Thanking in advance. Cheers. Tan Shao Yi

[Dovecot] Problems with dovecot-sieve on Debian Etch using dovecot LDA
by Samir M. Nassar 05 Jan '07

05 Jan '07

I am running debian etch with dovecot 1.0 rc15 from the debian repository with postfix 2.3 I am using virtual users in a postgreSQL database as taken from the dovecot wiki while making use of the password field for authentication I am using deliver as LDA and I am attempting to use the sieve plugin but try as I might I can't seem to get it working. Am I wrong in thinking that a sieve daemon should become active when dovecot starts? Here is my .dovecot.sieve require "fileinto"; if address :is "from" "foo@example" { fileinto ".INBOX.test"; } else { # The rest goes into INBOX # default is "implicit keep", we do it explicitly here keep; } Here is my dovecot.conf: base_dir: /var/run/dovecot/ log_path: /var/log/dovecot/dovecot.log info_log_path: /var/log/dovecot/info.log log_timestamp: %Y-%m-%d %H:%M:%S syslog_facility: mail protocols: imaps listen: *:143 ssl_listen: ssl_disable: no ssl_ca_file: ssl_cert_file: xxxx.pem ssl_key_file: xxxx.pem ssl_key_password: ssl_parameters_regenerate: 168 ssl_cipher_list: ssl_verify_client_cert: no disable_plaintext_auth: no verbose_ssl: no shutdown_clients: yes nfs_check: yes version_ignore: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_user: dovecot login_greeting: Dovecot ready. login_log_format_elements: user=<%u> method=%m rip=%r lip=%l %c login_log_format: %$: %s login_process_per_connection: yes login_chroot: yes login_greeting_capability: no login_process_size: 32 login_processes_count: 3 login_max_processes_count: 128 login_max_connections: 256 valid_chroot_dirs: mail_chroot: max_mail_processes: 1024 verbose_proctitle: no first_valid_uid: xxxx last_valid_uid: xxxx first_valid_gid: xxxx last_valid_gid: xxxx mail_extra_groups: default_mail_env: mail_location: maildir:/home/%d/mailboxes/%n mail_cache_fields: flags mail_never_cache_fields: imap.envelope mail_cache_min_mail_count: 0 mailbox_idle_check_interval: 30 mail_debug: no mail_full_filesystem_access: no mail_max_keyword_length: 50 mail_save_crlf: no mail_read_mmaped: no mmap_disable: no mmap_no_write: no lock_method: fcntl maildir_stat_dirs: no maildir_copy_with_hardlinks: no mbox_read_locks: fcntl mbox_write_locks: dotlock fcntl mbox_lock_timeout: 300 mbox_dotlock_change_timeout: 120 mbox_min_index_size: 0 mbox_dirty_syncs: yes mbox_very_dirty_syncs: no mbox_lazy_writes: yes dbox_rotate_size: 2048 dbox_rotate_min_size: 16 dbox_rotate_days: 1 umask: 63 mail_drop_priv_before_exec: no mail_executable: /usr/lib/dovecot/imap mail_process_size: 256 mail_plugins: mail_plugin_dir: /usr/lib/dovecot/modules/imap mail_log_prefix: %Us(%u): imap_max_line_length: 65536 imap_capability: imap_client_workarounds: outlook-idle pop3_no_flag_updates: no pop3_enable_last: no pop3_reuse_xuidl: no pop3_lock_session: no pop3_uidl_format: pop3_client_workarounds: pop3_logout_format: top=%t/%p, retr=%r/%b, del=%d/%m, size=%s auth default: mechanisms: login realms: default_realm: cache_size: 0 cache_ttl: 3600 executable: /usr/lib/dovecot/dovecot-auth user: root chroot: username_chars: abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@ username_translation: username_format: %n@%d master_user_separator: anonymous_username: anonymous krb5_keytab: verbose: yes debug: yes debug_passwords: yes ssl_require_client_cert: no ssl_username_from_cert: no count: 1 worker_max_count: 30 process_size: 256 passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf deny: no pass: no master: no userdb: driver: sql args: /etc/dovecot/dovecot-sql.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 438 user: group: master: path: /var/run/dovecot/auth-master mode: 438 user: group: Thank you very much, Samir M.

[Dovecot] Corrupted transaction log
by Paul Warren 04 Jan '07

04 Jan '07

I've just installed dovecot and am trying to use it to access my Maildir folders. Unfortunately: 1 SELECT INBOX 1 NO Internal error occurred. Refer to server log for more information. [2006-12-22 18:06:11] Log says: Dec 22 17:55:56 sphinx dovecot: IMAP(pdw): Corrupted transaction log file /home/pdw/Maildir/dovecot.index.log: record size too small (type=0x20, offset=24, size=0) Dec 22 17:55:57 sphinx dovecot: IMAP(pdw): Unexpected transaction log desync with index /home/pdw/Maildir/dovecot.index Dec 22 17:55:57 sphinx dovecot: IMAP(pdw): Unexpected transaction log desync with index /home/pdw/Maildir/dovecot.index Any clues? Deleting ~/Maildir/dovecot* doesn't seem to help. I can't find any documentation relating to the transaction log, or an explanation of why a fresh install of dovecot might choose to create a corrupt one. thanks, Paul

[Dovecot] Allow plaintext auth from local network?
by Marc Haber 04 Jan '07

04 Jan '07

Hi, I have dovecot 1.0rc15 on Debian and would like to allow plaintext auth not only from the local IP address but from the entire local network, but not from everywhere. Is that configurable? I am looking for something like "allow_plaintext_auth = 10.8.0.0/24".

[Dovecot] Custom login_greeting per virtual server?
by Cassidy B. Larson 04 Jan '07

04 Jan '07

Just a quick question, nothing broke. I setup about 5 virtual servers. It's great! I can define which protocols to listen on per server. Just curious why I can specify a unique "login_dir" per server, but not a unqiue login_greeting? Appears dovecot always shows the first login_greeting from the first virtual server. Intended this way? -c

[Dovecot] customizable idle login timeouts?
by Cassidy B. Larson 04 Jan '07

04 Jan '07

We're in the process of migrating from mbox over to maildir. I'm running into a problem with the proxy and timeouts. Appears the idle timeout is set to 60 seconds. This is a bit too low for some of our large mbox files :( Any plans on adding the: #define CLIENT_LOGIN_IDLE_TIMEOUT 60 #define AUTH_REQUEST_TIMEOUT to the .conf file to be tunable on the fly? I ended up just patching the couple of files in question, but it'd be nice.. Cassidy

[Dovecot] Urgent - Setup DoveCot with Plesk
by iSquareOne LLC 03 Jan '07

03 Jan '07

Hey, all, I am trying to setup DoveCot with Plesk. But I could not go through the last step. Setup: MySQL 5.0.22 Qmail Plesk 7.5 DoveCot v1.0 RC15 The problem: I setup sql.conf for user query and password query. I tried different ways, DoveCot always says "Authentication failed". Here are my two SQLs. user_query = SELECT concat('/var/qmail/mailnames/', d.name, '/', m.mail_name) as home, concat('/var/qmail/mailnames/', d.name, '/', m.mail_name) as mail, 101 AS uid, 12 AS gid, 'dirsize:storage=1000000' AS quota FROM accounts a, mail m, domains d WHERE a.id = m.account_id AND d.id=m.dom_id AND m.mail_name='%n' AND d.name='%d' I manully fill in %n=admin and %d=test.com to test it and it worked fine The result is: home,mail,uid,gid,quota "/var/qmail/mailnames/test.com/admin","/var/qmail/mailnames/test.com/admin","101","12","dirsize:storage=1000000" password_query = SELECT concat(m.mail_name, '@',d.name) as user, a.password as password, concat('/var/qmail/mailnames/', d.name, '/', m.mail_name) as userdb_home, concat('maildir:/var/qmail/mailnames/', d.name, '/', m.mail_name) as userdb_mail, 101 as userdb_uid, 12 as userdb_gid FROM accounts a, mail m, domains d WHERE a.id = m.account_id AND d.id=m.dom_id AND m.mail_name='%n' AND d.name='%d' The result is: user,password,userdb_home,userdb_mail,userdb_uid,userdb_gid "admin(a)test.com","password","/var/qmail/mailnames/test.com/admin","maildir:/var/qmail/mailnames/test.com/admin","101","12" I don't know what DoveCot is expecting to get from the SQL result. Please let me know if I missed anything. Thank you very much! __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

[Dovecot] Error reading configuration file
by Justin Pearce 03 Jan '07

03 Jan '07

Good day, I seem to be having an issue using dovecot 1.0 rc15. I compiled the source with the following configure command: CPPFLAGS="-I/usr/local/include/mysql" LDFLAGS="-L/usr/local/lib/mysql" -lmysqlclient" ./configure -with-mysql -with-sql-drivers=mysql Did make and make install and set the dovecot-example.conf to dovecot.conf and tried running the program and got the following error: Error: Error in configuration file on line 50: expecting '=' Line 50 of the default config is a comment, which struck me as odd. So, I uninstalled and tried building with no options. I did a make uninstall, removed the /usr/local/lib/dovecot directory did make and make install and tried the program. This time it didn't crash about the config file, but the mail.err log notes that the child processes died on an error 89, apparently unable to figure our what pam was. I'm wondering why the thing seems to work if I do not build for mysql but if I want mysql, it breaks in the manner it does? Is it a bug, or am I doing it wrong (which is a real possibility). Any help soon would be appreciated, as my boss keeps asking 'So, when is that mail server going to be done?'. :) Justin Pearce Information Technology/Programming Price Video Productions JustinP(a)PriceVideo.com 361-572-3810 800-733-3810 Fax: 361-572-3894 www.PriceVideo.com

[Dovecot] Dovecot and Mail.app
by Barry Warsaw 03 Jan '07

03 Jan '07

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I'm trying to convert a courier-imap installation over to using Dovecot, but I'm having some problems with Mail.app on OS X. FTR, we use both Mail.app and Thunderbird. Note that in the Mail.app preferences, I have a blank IMAP Path Prefix. I'm using Dovecot 1.0_rc15 on Gentoo, and Mail.app from OS X 10.4.8, Thunderbird 1.5.0.9. With the old courier setup, in Mail.app I would see a top level Inbox folder, with an inbox icon'd folder underneath that representing the IMAP account. That IMAP account subfolder would be the inbox of that account. Under that, I'd see all the subfolders for that account. Something like: Inbox Account1 Folder1 Folder2 ... Account2 FolderA Outbox Drafts Sent Junk SmartFolder1 SmartFolder2 Note that a straight copy from the courier Maildir leaves me with directories like ~/Maildir/.Folder1 and ~/Maildir/.Folder2 -- IOW, they do not have .INBOX. prefix. I tried adding a "namespace private" section, with separator, prefix, and inbox values as specified in the docs. This gives me the same layout in the Mail.app u/i as with Courier, but there's a big problem: none of the folders under Account1 have any contents. The folders are there, and in the right location, but they have zero messages (even though they certainly have messages in the filesystem). Nothing in the Dovecot log file indicates any problem. But if I hover over say Folder1 in the Mail.app u/i, I see a popup message like: Mail was unable to open this mailbox on the server "imap.example.com". The server error encountered was: Unknown namespace Moving over to Thunderbird though, I see exactly what I want to see. Top level expandable is the account, with Inbox under that, which expands to all my folders. Of course Thunderbird supports subscriptions, which Mail.app does not, so I only see the folders I've subscribed to. Clearly, there's some weird interaction between Mail.app and Dovecot. Next, I tried removing the 'prefix' value from the "namespace private" section, and restarted Dovecot. Now the Mail.app u/i is different, but all the folders have their contents back! The u/i now shows: Inbox Account1 Account2 FolderA Outbox Drafts Sent Junk SmartFolder1 SmartFolder2 Account1 Folder1 Folder2 IOW, all of account1's folders live under a separate expandable section below the top level Inbox expandable (that section has a little world icon instead of the little inbox icon). Account1's inbox lives in a different section from its folders, but it has no subfolders. Looking back at Thunderbird, I notice that all the subscribed folders are now at the same level as the Inbox, just under the account name. I.e. Account1 Inbox Trash Folder1 Folder2 ... I suppose I can live with the Mail.app behavior sans the prefix setting in the namespace section, but it's not ideal. I'd really like to know why Mail.app has a problem with this! Why are the folders there but the contents empty? Is there any way to increase the logging that Dovecot does to understand what the Mail.app client is sending and why Dovecot is sending back that error? Any help would be greatly appreciated! - -Barry P.S. I wasn't able to use courier2dovecot.sh from the wiki (I think others had problems with running it on Linux as well, probably due to the different rename(1) syntax). The courier2dovecot.py file was no longer available, so I wrote my own. I can make that available to folks if there's any interest. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (Darwin) iQCVAwUBRZC8sXEjvBPtnXfVAQK90gQAjFhEH+vIPh7pnY4MuOTU8ChWfJ57ppIQ g0HvHidiD5nOfd8pfpsfacdD1nC40cRlpnJkR6vcahvqQsLzSUzUMwVlUqP2IDSE jGvZGpGSBpjTHV/ktWbyJhPo9+ehVxiq+qEfbDgfw9iqBtulOXe4M25iUKO8tsuA n2bCHHoUXuk= =hxad -----END PGP SIGNATURE-----

[Dovecot] Dovecot SASL vs. Micro$oft Outlook and Outlook Express
by Tom Kovar 02 Jan '07

02 Jan '07

Hi, I have just started using Dovecot (1.0.10) SASL behind my Postfix (2.3.3). Everything works fine, as long as I send the SMTP AUTH command manually. When using M$ Outlook (2000 and 2003) and Outlook Express 6, authentification always fails. Turning on the Dovecot auth debug on reveals the reason: Dovecot SASL expects, in accordance with the standards, the following format of the SMTP AUTH command (using the PLAIN auth mechanism): AUTH PLAIN base64_encode("username\0username\0password") whereas the M$ clients send as the second argument only base64_encode("username\0password"), which naturally leads to authentification failure. Postfix apparently does not play any role in this game, as it simply passes the received command arguments to dovecot. Before I start hacking the source myself, I just wanted to ask if somebody has a patch for this M$ shortcoming - as the damned M$ clients are very much spread, I would assume this should be the case... Thanx, --- Tom
