I thought it would be nice to have vboxes insead of user logins ... Now I am confuesed and in trouble .. My server serves 2 domains so user1(a)domain1.com is the same as user1(a)domain2.org I've created the mail_location string with %n and static userdb with %n dovecot creates 2 mail user directories user1(a)domain1.com user1(a)domain2.org What the heck am I missing .. ??

[Dovecot] problem compiling pigeonhole + my fix
by Andreas Schulze 19 May '10

19 May '10

hello, yesterday I tried to package dovecot-2.0beta5 + pigeonhole from Mercurial repository. I put pigeonhole as a subdir in the dovecot sourcetree. Following http://hg.rename-it.nl/dovecot-2.0-pigeonhole/raw-file/tip/INSTALL I called ./autogen.sh; ./configure --with-dovecot=..; make In the buildprocess I saw this output ( from autogen.sh ): Putting files in AC_CONFIG_AUX_DIR, `..'. libtoolize: `config.guess' exists: use `--force' to overwrite libtoolize: `config.sub' exists: use `--force' to overwrite libtoolize: `ltmain.sh' exists: use `--force' to overwrite I dont know *why* AC_CONFIG_AUX_DIR is .. but in .. there are the mentioned files (from dovecot) already present. The following make failed with less helpfull errors. -> my fix is to call "autoreconf -i -f" again after autogen.sh should -f be added to autogen.sh ? -- Andreas Schulze Internetdienste | P532 DATEV eG 90329 Nürnberg | Telefon +49 911 319-0 | Telefax +49 911 319-3196 E-Mail info @datev.de | Internet www.datev.de Sitz: 90429 Nürnberg, Paumgartnerstr. 6-14 | Registergericht Nürnberg, GenReg Nr.70 Vorstand Prof. Dieter Kempf (Vorsitzender) Dipl.-Kfm.

Re: [Dovecot] A new director service in v2.0 for NFS installations

We've talked about that before, that the proxy could for instance fall back to itself as the 'final server'. The people in here want to use their existing monitoring script that would do "ssh host doveadm director remove 1.2.3.4". But on top of that, yeah, maybe proxy itself could tell director that some host is down and retry the lookup. Although determining when it's down might not be fully reliable always, so I'm a bit worried that proxy could sometimes fail to connect to a mail server even if it's up (but e.g. with high load, temporary small network problem, etc).

That file contribute to performance improvement, so I want to register myself with crontab. Please teach how to make dovecot.index and dovecot.index.cache manyually. Note.

[Dovecot] double write-locking dovecot.index.log
by Mike Abbott 19 May '10

19 May '10

Dovecot's transactions often write-lock dovecot.index.log twice (without unlocking in between), and then unlock it twice. Is that intended, or is that a bug? If I read the man pages correctly, double write-locking is pointless but safe. But double unlocking could cause data corruption during the period between the first and second unlocks, because the locks don't nest (are not refcounted). The first unlock leaves the file totally unlocked. Could this be the source of some index corruption errors? For example: 1. Process A acquires a F_WRLCK on a file. 2. Through a different code path, process A again acquires a F_WRLCK on the same file. Since these locks don't nest this is essentially a no-op. 3. Process A modifies the file. 4. Process A unlocks the file to undo the lock in step 2. Now the file has no lock on it at all. 5a. Process B locks, modifies, and unlocks the file. 5b. Process A also modifies the file, thinking that it still has a write lock. 6. Process A unlocks the file to undo the lock in step 1, but this is another no-op. Data corruption is possible if steps 5a and 5b conflict, or if 5b uses stale data. Here is a code path in dovecot-1.2.11 which exhibits the above behavior. "Outer" write lock: maildir_transaction_save_commit_pre -> maildir_transaction_save_commit_pre_sync -> maildir_sync_index_begin -> mail_index_sync_begin -> mail_index_sync_begin_to -> mail_index_sync_begin_init -> mail_transaction_log_sync_lock -> mail_transaction_log_lock_head -> mail_transaction_log_file_lock -> mail_index_lock_fd -> file_wait_lock -> file_lock_do "Inner" write lock: maildir_transaction_save_commit_pre -> maildir_sync_index_finish -> mail_index_sync_commit -> mail_index_write -> mail_transaction_log_rotate -> mail_transaction_log_file_create -> mail_transaction_log_file_create2 -> mail_transaction_log_file_lock -> mail_index_lock_fd -> file_wait_lock -> file_lock_do The file being locked is the same, dovecot.index.log. In another case, maildir_sync_index_begin is reached this way (outer lock): mailbox_sync -> mailbox_sync_init -> maildir_storage_sync_init -> maildir_sync_context -> maildir_sync_index_begin -> mail_index_sync_begin -> etc. And maildir_sync_index_finish is reached this way (inner lock): mailbox_sync -> mailbox_sync_init -> maildir_storage_sync_init -> maildir_sync_context -> maildir_sync_index_finish -> etc. Could these lead to data corruption? Please let me know if you need any more information. Thanks.

[Dovecot] how authentication works?
by Mihamina Rakotomandimby 18 May '10

18 May '10

Manao ahoana, Hello, Bonjour, I've read: http://wiki.dovecot.org/Authentication/PasswordSchemes I have a users database with clear plain passwords. Dovecot authenticates users without problems against it. Now, it's time to move to CRYPT scheme. Before that, I would like to know how things happen. He have: - the user, (entering his password in the MUA) - the user's MUA (Thunderbird, Outlook, Squirrelmail,...) - the POP or IMAP server - the users database (mySQL) with username and crypt()'d password How I think the process is: - the user enters his password in a clear way. - the MUA sends the password as the user entered it to the POP or IMAP server - the POP or IMAP server fetches the password from the database - the POP or IMAP server crypt()'s the user entered password - the POP or IMAP server compares crypt()'d ones and gives his response Am I close enough to reality? Too far? Misaotra, Thanks, Merci. -- Architecte Informatique chez Blueline/Gulfsat: Administration Systeme, Recherche & Developpement +261 3456 000 19
