[Dovecot] service anvil and ssl-params not starts with dovecot started
by Dewey Du 28 Sep '13

28 Sep '13

Hi My dovecot started with the error below. What's the most possible reason for the error? “2013-08-28 11:41:40 ”master: Info: Dovecot v2.2.5 starting up (core dumps disabled) “2013-08-28 11:42:00 ”anvil: Fatal: Error reading configuration: Timeout reading config from /var/run/dovecot/config “2013-08-28 11:42:00 ”master: Error: service(anvil): command startup failed, throttling for 2 secs “2013-08-28 11:42:00 ”ssl-params: Fatal: Error reading configuration: Timeout reading config from /var/run/dovecot/config “2013-08-28 11:42:00 ”master: Error: service(ssl-params): command startup failed, throttling for 2 secs Actually, After dovecot starts, I can telnet 110, but it takes 30seconds or so to get through the authentication. I suspect whether the error above cause the issue or not.

[Dovecot] v2.2.6 released
by Timo Sirainen 27 Sep '13

27 Sep '13

http://dovecot.org/releases/2.2/dovecot-2.2.6.tar.gz http://dovecot.org/releases/2.2/dovecot-2.2.6.tar.gz.sig I didn't have time to look into the latest reported dsync replication bugs, but this release should have been done a long time ago already and I'm busy for next few days, so no more waiting. Things seem to be working quite well in general though. * acl: If public/shared namespace has a shared subscriptions file for all users, don't list subscription entries that are not visible to the user accessing it. + doveadm: Added "auth lookup" command for doing passdb lookup. + login_log_format_elements: Added %{orig_user}, %{orig_username} and %{orig_domain} expanding to the username exactly as sent by the client (before any changes auth process made). + Added ssl_prefer_server_ciphers setting. + auth_verbose_passwords: Log the password also for unknown users. + Linux: Added optional support for SO_REUSEPORT with inet_listener { reuse_port=yes } - director: v2.2.5 changes caused "SYNC lost" errors - dsync: Many fixes and error handling improvements - doveadm -A: Don't waste CPU by doing a separate config lookup for each user - Long-running ssl-params process no longer prevents Dovecot restart - mbox: Fixed mailbox_list_index=yes to work correctly

[Dovecot] Index error copying compressed message

Hi. Dovecot 2.2, with the zlib plugin, I think we're getting bad index entries on IMAP COPY. On copying a message to an empty folder, in the dovecot error log I see: Sep 19 20:34:25 imap01 dovecot: imap(grain(a)rp-auth-test.com): Error: Cached message size smaller than expected (615 < 971) Sep 19 20:34:25 imap01 dovecot: imap(grain(a)rp-auth-test.com): Error: Corrupted index cache file /mail/index01/434/860/grain(a)rp-auth-test.com/.Bup/dovecot.index.cache: Broken physical size for mail UID 0 Sep 19 20:34:25 imap01 dovecot: imap(grain(a)rp-auth-test.com): Error: read() failed: Invalid argument (uid=0) (Note this happens from the copy operation, not a subsequent access.

[Dovecot] Released Pigeonhole v0.4.2 for Dovecot v2.2.6 and Pigeonhole v0.3.6 for Dovecot v2.1.17.
by Stephan Bosch 27 Sep '13

27 Sep '13

Hello Dovecot users, Now that Dovecot v2.2.6 is released, I can release a new Pigeonhole. Due to the SO_REUSEPORT changes in Dovecot, this Pigeonhole release will not compile cleanly against older Dovecot releases. This release is mainly about bugfixes. I also made a new release for Dovecot v2.1.17 that includes most of these fixes and some older ones. A word of warning for people using doveadm sync in combination with sieve: make sure you update both sides of the replication to avoid problems after upgrade. The attribute sub-tree under which Sieve scripts are replicated has moved to a different root. Since we expect that very few people are affected, there is no facility for backwards compatibility. This is no problem as long as both sides are upgraded. There is one new feature for the Sieve vacation extension. Normally vacation replies are sent with <> sender to prevent mail loops. A setting is provided to override this behavior (doc/extensions/vacation.txt), as requested on the mailing list. This is not a violation of the specification, but use this with care. Changelog v0.4.2: * Incompatible change in Sieve doveadm plugin: the root attribute for Sieve scripts is changed. Make sure that you update both sides of a dsync setup simultaneously when Sieve is involved, otherwise synchronization will likely fail. + Added support for sending Sieve vacation replies with an actual sender, rather than the default <> sender. Check the updated doc/extensions/vacation.txt for more information. - Fixed a binary code read problem in the `set' command of the Sieve variables extension. Using the set command with a modifier and an empty string value would cause code corruption problems while running the script. - Various fixes for doveadm-sieve plugin, mostly crashes. These include a fix for the `Invalid value for default sieve attribute' problem. - Various fixes for compiler and static analyzer warnings, e.g. as reported by CLang and on 32 bit systems. - Fixed the implementation of the new :options flag for the Sieve include extension. - Fixed potential segfault bug at deinitialization of the lda-sieve plugin. - Fixed messed up hex output for sieve-dump tool. Changelog v0.3.6: - Fixed a binary code read problem in the `set' command of the Sieve variables extension. Using the set command with a modifier and an empty string value would cause code corruption problems while running the script. - Various fixes for compiler and static analyzer warnings, as reported by CLang. - ManageSieve: Fixed '[' ']' stupidity for response codes (only happened before login). - Fixed setting name in example-config/conf.d/20-managesieve.conf. - Fixed messed up hex output for sieve-dump tool. The releases are available as follows: http://www.rename-it.nl/dovecot/2.2/dovecot-2.2-pigeonhole-0.4.2.tar.gz http://www.rename-it.nl/dovecot/2.2/dovecot-2.2-pigeonhole-0.4.2.tar.gz.sig http://www.rename-it.nl/dovecot/2.1/dovecot-2.1-pigeonhole-0.3.6.tar.gz http://www.rename-it.nl/dovecot/2.1/dovecot-2.1-pigeonhole-0.3.6.tar.gz.sig Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information. Have fun testing this new release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

[Dovecot] Strange errors with imapc+acl in 2.2.x
by René Neumann 27 Sep '13

27 Sep '13

Hi, after migrating to 2.2 (currently using 2.2.5), I see strange error messages when using imapc + public namespace + acl My setup: I create a public shared mailbox with imapc as location. Then I restrict this mailbox to one user only using ACLs. This works for this one special user, but for all others an error gets logged and they can't access their mailbox anymore: Sep 24 18:09:46 [dovecot] imap(other(a)my.domain): Error: user other(a)my.domain: Initialization failed: Namespace 'Gemeinsam.': Ambiguous mail location setting, don't know what to do with it: yes (try prefixing it with mbox: or maildir:) Sep 24 18:09:46 [dovecot] imap(other(a)my.domain): Error: Invalid user settings. Refer to server log for more information. My config (relevant parts): ------------------ Dovecot conf ---------------- imapc_host = some_host imapc_port = 143 imapc_user = some_user imapc_password = some3$pwd imapc_ssl = starttls imapc_ssl_verify = no namespace gemeinsam { type = public separator = . location = imapc: prefix = Gemeinsam. subscriptions = no } # I also tried different combinations of hidden and list plugin { acl = vfile:/etc/dovecot/global-acls:cache_secs=300 } ------------- /etc/dovecot/global-acls/Gemeinsam ------- anyone user=special(a)my.domain lrwstipekxa -------------------------------------------------------- Does anyone have any thoughts about this? Thanks, René

[Dovecot] Dovecot extremely slow!
by Patricio Rojo 27 Sep '13

27 Sep '13

Please help, Dovecot is running extremely slow for the last couple of weeks and it seems to be getting worse (or my patience running short). I attach the 10-master configuration and the log file after running strace according to: http://wiki.dovecot.org/Debugging/ProcessTracing I can click on an email and wait for a minute or more before receiving a connection dropped or no error at all. I use many clients (thunderbird, windows 8 mail, maildroid for android, squirrelmail) and they all have similar behavior. It happens both in the inbox and on imap subfolders. Sometimes it helps changing subfolders back and forth. I have many imap folders organized in up to 3 levels of subfolders and use postfix for delivery. Let me know any other info you require. Thanks! Patricio
