Fortunately, it just involves reformatting the data and a little reconmfiguration of dovcot. If you can find the tool and disk space, it's well worth doing. Of course, when running a proverbial dinosaur, you're often more preoccupied with preventing the next proverbial meteorite strike. > What I meant was, are certain types of filenames "blocked" by policy from > being created via IMAP commands?

I never saw anything that could do that -- maybe you can torture the virtual mailbox facility to get that done. If all your concerned is dovecot dot-files, you can place the indices somewhere else other than the user's filesapace. > One last problem area is that many users have soft-links to mailboxes > located on a second drive, but these never appear in folder enumeration > lists or they appear grayed out in SeaMonkey/Thunderbird.

I wonder if there's > paranoia checking in the code that follows symbolic links to ensure > that uids/gids of the "owning" directory and the linked-to directory > (or files within it) are the same. It works for me. From what I see, the ownership of the symlink is ignored; it's the underlying file that counts. Maybe a subscription issue? Joseph Tam <jtam.home(a)gmail.com>

I resemble that remark. >> Warning: Transaction log file /home/luser/mail/.imap/INBOX/dovecot.index.log >> was locked for 95 seconds (rotating while syncing) Timo recently explained to me it's probably caused by slow I/O or processing.

You can disable dotclock altogether, but I don't think this is what you meant. You can use locking method "dotlock_try" rather than "dotlock" -- the former will ignore quota/permissions problems and plow on. (It still logs it.) You could also align luser's mail folder group with with luser's GID, which is usually what I do. Maybe locks are created even when files don't exist as there may be a race condition where another process is creating/deleting it at the same time. Joseph Tam <jtam.home(a)gmail.com>

v2.2.30 released
by Timo Sirainen 13 Jun '17

13 Jun '17

https://dovecot.org/releases/2.2/dovecot-2.2.30.tar.gz https://dovecot.org/releases/2.2/dovecot-2.2.30.tar.gz.sig * auth: Use timing safe comparisons for everything related to passwords. It's unlikely that these could have been used for practical attacks, especially because Dovecot delays and flushes all failed authentications in 2 second intervals. Also it could have worked only when passwords were stored in plaintext in the passdb. * master process sends SIGQUIT to all running children at shutdown, which instructs them to close all the socket listeners immediately. This way restarting Dovecot should no longer fail due to some processes keeping the listeners open for a long time. + auth: Add passdb { mechanisms=none } to match separate passdb lookup + auth: Add passdb { username_filter } to use passdb only if user matches the filter. See https://wiki2.dovecot.org/PasswordDatabase + dsync: Add dsync_commit_msgs_interval setting. It attempts to commit the transaction after saving this many new messages. Because of the way dsync works, it may not always be possible if mails are copied or UIDs need to change. + imapc: Support imapc_features=search without ESEARCH extension. + imapc: Add imapc_features=fetch-bodystructure to pass through remote server's FETCH BODY and BODYSTRUCTURE. + imapc: Add quota=imapc backend to use GETQUOTA/GETQUOTAROOT on the remote server. + passdb imap: Add allow_invalid_cert and ssl_ca_file parameters. + If dovecot.index.cache corruption is detected, reset only the one corrupted mail instead of the whole file. + doveadm mailbox status: Add "firstsaved" field. + director_flush_socket: Add old host's up/down and vhost count as parameters - More fixes to automatically fix corruption in dovecot.list.index - dsync-server: Fix support for dsync_features=empty-header-workaround - imapc: Various bugfixes, including infinite loops on some errors - IMAP NOTIFY wasn't working for non-INBOX if IMAP client hadn't enabled modseq tracking via CONDSTORE/QRESYNC. - fts-lucene: Fix it to work again with mbox format - Some internal error messages may have contained garbage in v2.2.29 - mail-crypt: Re-encrypt when copying/moving mails and per-mailbox keys are used. Otherwise the copied mails can't be opened. - vpopmail: Fix compiling

rescann / reindex / rebuild a subfolder structure
by Götz Reinicke - IT Koordinator 13 Jun '17

Hi, an user is missing all mail from a folder and all subfolders which are still saved in the users maildir directory on the dovecot server. From an imap client she sees the main folder but empty. No subfolders. She told me with an other imap client and a new created account she has the same problem. Question: Can I resync / regenerate some folder... index.... something....-files from the dovecot side? Thanks for hints and regards . Götz

This is a consequence of writing secure software: it employs least privilege so that a fault will not result in someone being able to mess around with someone else's mail (or indices). GID can also govern access to shared mailboxes. Joseph Tam <jtam.home(a)gmail.com>

Pardon my naievty, but couldn't you just remove this namespace altogether and get rid of at least one set of duplicates (although it probably keep the non-preferred one).

service(auth): command startup failed?
by HL1234 12 Jun '17

Hello, I need help because since some days I can not figure out what error this is and where it come from. I have used dovecot since years. Know after an update it is broken. First I like to give you some data: It's a FreeBSD 11.0 Server with sendmail (SMTP) and dovecot for IMAP with SSL. #dovecot --build-options Build options: ioloop=kqueue notify=kqueue ipv6 openssl io_block_size=8192 Mail storages: shared mdbox sdbox maildir mbox cydir imapc pop3c raw fail SQL drivers: mysql Passdb: checkpassword ldap pam passwd passwd-file sql Userdb: checkpassword ldap nss passwd prefetch passwd-file sql #dovecot --version 2.2.30.2 (c0c463e) I install the update with the FreeBSD ports. Before the update all was running fine. The state know is: form my client Outlook I can send eMail above SMTP. When I try to get my eMails by the IMAP-Server it is blocked. I have look around in the config files but I see nothing what has could be changed. I have tried to make new *.pem files with using the script in /usr/local/share/examples/dovecot/ but this havn't bring a solution. I need help for this error i see in the logs: dovecot.log master: Error: service(auth): command startup failed, throttling for 2 secs auth: Error: auth: environment corrupt; missing value for DOVECOT_ auth: Fatal: unsetenv(RESTRICT_SETUID) failed: Bad address auth: Error: auth: environment corrupt; missing value for DOVECOT_ auth: Fatal: unsetenv(RESTRICT_SETUID) failed: Bad address ..... dovecot-info.log imap-login: Info: Disconnected: Auth process broken (disconnected before auth was ready, waited 1 secs): user=<>, rip=77.178.105.78, lip=88.74.25.120, TLS Jun 12 23:01:15 imap-login: Info: Disconnected: Auth process broken (disconnected before auth was ready, waited 8 secs): user=<>, rip=58.218.194.81, lip=88.74.25.120, TLS handshaking .... dovecot-debug.log imap-login: Debug: SSL: where=0x10, ret=1: before/accept initialization [77.178.105.78] imap-login: Debug: SSL: where=0x2001, ret=1: before/accept initialization [77.178.105.78] imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 read client hello A [77.178.105.78] imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 write server hello A [77.178.105.78] imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 write certificate A [77.178.105.78] imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 write key exchange A [77.178.105.78] imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 write server done A [77.178.105.78] imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 flush data [77.178.105.78] imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 read client certificate A [77.178.105.78] imap-login: Debug: SSL: where=0x2002, ret=-1: SSLv3 read client key exchange A [77.178.105.78] imap-login: Debug: SSL: where=0x2002, ret=-1: SSLv3 read client key exchange A [77.178.105.78] auth: Debug: Loading modules from directory: /usr/local/lib/dovecot/auth auth: Debug: Module loaded: /usr/local/lib/dovecot/auth/lib20_auth_var_expand_crypt.so auth: Debug: Read auth token secret from /var/run/dovecot//auth-token-secret.dat Have anyone an idea what is going wrong and how to fix it?
