[Dovecot] pop3 not autocreating directory structure
by Jan-Frode Myklebust 15 Feb '12

15 Feb '12

We use: mail_home = /srv/mailstore/%256LRHu/%Ld/%Ln mail: mdbox:~/mdbox and I just noticed one of our newly provisioned users initially failed to pop her mails. I saw several of these: dovecot:: pop3(new.user(a)example.net): Error: Couldn't open INBOX: Mailbox doesn't exist: INBOX dovecot:: pop3(new.user(a)example.net): Couldn't open INBOX top=0/0, retr=0/0, del=0/0, size=0 before she switched to imap and then everything looked fine: dovecot:: imap(new.user(a)example.net): Disconnected: Logged out bytes=11/338 Looking at the timestamps in the filesystem I see that the users home directory wasn't created before switcing to imap. Is this a know problem? -jf

[Dovecot] v2.1.rc7 released
by Timo Sirainen 15 Feb '12

15 Feb '12

http://dovecot.org/releases/2.1/rc/dovecot-2.1.rc7.tar.gz http://dovecot.org/releases/2.1/rc/dovecot-2.1.rc7.tar.gz.sig Okay, one more RC, because I needed a new feature implemented and forgot I wasn't supposed to do any changes anymore before v2.1.0. After that I figured I'll just do a few more changes and release RC7. So, v2.1.0 will probably be released within 1-2 days. So, the one new feature is: + Added ignore_on_failure setting for namespaces. If namespace initialization fails with this enabled (e.g. permission denied), the namespace is silently skipped for the user. Also (not really worth mentioning in NEWS) if you now connect to imap/pop3 port when auth process is misconfigured and dies, instead of hanging the client for 5 mins it gets disconnected pretty much immediately.

[Dovecot] R: Re: LMTP : Can't handle mixed proxy/non-proxy destinations
by cinzia.delcoiro＠libero.it 15 Feb '12

15 Feb '12

Hi Timo, I'm writing to alert you that even in version 2.1. we have the error: "Can't handle mixed proxy/non-proxy destinations" when we write to two users: one existent and one not. The error occurs randomly. I configure LDAP query in the file : dovecot-ldap.conf in this way: pass_attrs = mail=user,userPassword=password,=proxy=y,mailHost=host, =proxy_timeout=600 specifying "=proxy=y" in order to proxy every mail. As workaround, can I configure a static "host" for non-existing users?

[Dovecot] v2.1.rc6 released
by Timo Sirainen 15 Feb '12

15 Feb '12

http://dovecot.org/releases/2.1/rc/dovecot-2.1.rc6.tar.gz http://dovecot.org/releases/2.1/rc/dovecot-2.1.rc6.tar.gz.sig I've finally finished all of my email backlog. If you haven't received an answer to some question/bugreport, resend the mail. This is hopefully the last v2.1 RC. If I don't receive any (serious) bug reports about this release in next few days, I'll just change the version number to v2.1.0 (and maybe update man pages, some are still missing..) I'll also create dovecot-2.2 hg repository today and add some pending patches from Stephan there and start doing some early spring cleaning in there. :) Since v2.1.rc5 there have been lots of small fixes and logging improvements, but I also did a few bigger things since they really had to be done soon and I didn't want v2.2.0 release to be only a few months after v2.1.0 with barely any new features. * Added automatic mountpoint tracking and doveadm mount commands to manage the list. If a mountpoint is unmounted, error handling is done by assuming that the files are only temporarily lost. This is especially helpful if dbox alt storage becomes unmounted. * Expire plugin: Only go through users listed by userdb iteration. Delete dict rows for nonexistent users, unless expire_keep_nonexistent_users=yes. * LDA's out-of-quota mails now include DSN report instead of MDN. + LDAP: Allow building passdb/userdb extra fields from multiple LDAP attributes by using %{ldap:attributeName} variables in the template. + doveadm log errors shows the last 1000 warnings and errors since Dovecot was started. + Improved multi-instance support: Track automatically which instances are started up and manage the list with doveadm instance commands. All Dovecot commands now support -i <instance_name> parameter to select the instance (instead of having to use -c <config path>). See instance_name setting. + doveadm mailbox delete: Added -r parameter to delete recursively + doveadm acl: Added "add" and "remove" commands. + Updated to Unicode v6.1 - mdbox: When saving to alt storage, Dovecot didn't append as much data to m.* files as it could have. - dbox: Fixed error handling when saving failed or was aborted - IMAP: Using COMPRESS extension may have caused assert-crashes - IMAP: THREAD REFS sometimes returned invalid (0) nodes. - dsync: Fixed handling non-ASCII characters in mailbox names.

[Dovecot] doveadm director proxy
by Jan-Frode Myklebust 15 Feb '12

15 Feb '12

I'm trying to configure a doveadm service that will proxy trough our directors, following the recipie at: http://wiki2.dovecot.org/Director#Doveadm_server So on the backends I have: service doveadm { inet_listener { port = 24245 address = * } } doveadm_proxy_port = 24245 local 192.168.42.0/24 { doveadm_password = suPerSeecret } I assume the "local" line is supposed to point at my local network..? On the directors I have the same, plus: protocol doveadm { auth_socket_path = director-userdb } When testing "doveadm quota" on the directors, it complained quota plugin not being loaded, so I added: mail_plugins=quota Then it complained about "doveadm_password not set, can't authenticate", so I added: doveadm_password = suPerSeecret in the main section. Now I get trough to my backend servers, but they complain about: dovecot:: doveadm: Error: doveadm client attempted non-PLAIN authentication Any ideas for what that might be? This is with dovecot v2.0.14. -jf

[Dovecot] Synchronization error in NFS
by Andy YB Hu 14 Feb '12

14 Feb '12

Hi there, Not sure whether it's a bug or env setting issue. I am running some concurrent testings under NFS. The dovecot (version 2.0.13) are deployed in 2 servers (same setup), whose maildir are on the file server via NFS. Here are the output of dovecot -n: [root@MyMachine src]$dovecot -n # 2.0.13: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 2.6.18-274.3.1.el5 i686 Red Hat Enterprise Linux Server release 5.7 (Tikanga) nfs auth_anonymous_username = andy auth_debug = yes auth_debug_passwords = yes auth_mechanisms = anonymous plain auth_verbose = yes auth_verbose_passwords = plain disable_plaintext_auth = no lock_method = dotlock log_path = /tmp/log mail_debug = yes mail_fsync = always mail_gid = andy mail_location = maildir:/tmp/NFS mail_nfs_index = yes mail_nfs_storage = yes mail_uid = andy mmap_disable = yes passdb { driver = pam } ssl = no userdb { driver = passwd } Here are what I am doing: One session running loop of COPY commands (while(1) COPY...) connects to one dovecot server; The other session running loop of SELECT commands (while(1) SELECT...) connects to the other dovecot server. Both are accessing the same mail box (/tmp/NFS); After some while (not accurate duration, maybe 2 seconds, or 1 min), I found the number of EXISTS returned from SELECT command is not correct(less than the real number). Then I stop the both sessions. In the /tmp/log: Feb 07 03:44:59 imap(andy): Error: Corrupted transaction log file /tmp/NFS/dovecot.index.log seq 2: Unexpected garbage at EOF (sync_offset=2204) Feb 07 03:44:59 imap(andy): Error: Index /tmp/NFS/dovecot.index: Lost log for seq=2 offset=2204 Feb 07 03:44:59 imap(andy): Warning: fscking index file /tmp/NFS/dovecot.index Then I tried to dump the index, sometime it's failed because of the index corruption. If not, it says: [root@MyMachine src]$doveadm dump /tmp/NFS > /tmp/dump ; vi /tmp/dump doveadm(root): Error: Log synchronization error at seq=2,offset=744 for /tmp/NFS/dovecot.index: Broken extension introduction: Headersize too large (2273345664) doveadm(root): Warning: fscking index file /tmp/NFS/dovecot.index doveadm(root): Error: fcntl(write-lock) locking failed for file /tmp/NFS/dovecot.index.log: Bad file descriptor doveadm(root): Error: mail_index_wait_lock_fd() failed with file /tmp/NFS/dovecot.index.log: Bad file descriptor doveadm(root): Error: Log synchronization error at seq=2,offset=744 for /tmp/NFS/dovecot.index: Broken extension introduction: Headersize too large (2273345664) doveadm(root): Warning: fscking index file /tmp/NFS/dovecot.index doveadm(root): Error: fcntl(write-lock) locking failed for file /tmp/NFS/dovecot.index.log: Bad file descriptor doveadm(root): Error: mail_index_wait_lock_fd() failed with file /tmp/NFS/dovecot.index.log: Bad file descriptor And sometime from the dump output, in the RECORD part: -- RECORDS: 5 RECORD: seq=1, uid=1, flags=0x00 RECORD: seq=2, uid=2, flags=0x00 RECORD: seq=3, uid=3, flags=0x00 RECORD: seq=4, uid=4, flags=0x00 RECORD: seq=5, uid=6, flags=0x00 The uid 5 is missed. but in uidlist file, it's there.. Here are all what I found. If you need additional information, pls let me know. The clock on the 3 machines are synchronized. You can also reproduce it if the 2 sessions are APPEND and SELECT. If both sessions are running towards the same dovecot server, even the maildir are on the NFS, it works very well without any error.
