[Dovecot] backtrace from postgres dict
by Steffen Kaiser 20 Dec '12

20 Dec '12

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, since I enabled ACLs I get following backtrace. It looks like that it happens if the ACLs had been changed only. Also, it looks like that it always happens 1 minute after last "dict: Info: pgsql(localhost): Connected to database dovecot", no matter if the user is logged in (and idle) or logged off. Postgres logs: "could not receive data from client: Connection reset by peer" and "unexpected EOF on client connection". Is there some TCP keep alive issue? Postgres is using the "system default" for TCP keep alive. I'm currently testing ACLs via telnet, so the activity with the ACL dict is pretty low, hence, an idle timeout would make much sense. # ../../sbin/dovecot --version 2.1.10 (a4f02f6c0d32) dict connect string: connect = host=localhost dbname=db user=user 2012-11-28 10:03:39 dict: Info: pgsql(localhost): Connected to database dovecot 2012-11-28 10:03:39 dict: Info: pgsql(localhost): Connected to database dovecot 2012-11-28 10:03:39 dict: Info: pgsql(localhost): Connected to database dovecot 2012-11-28 10:03:58 IMAP(user) [22922]: Info: Disconnected: Logged out in=23 out=763 2012-11-28 10:04:41 dict: Panic: file driver-pgsql.c: line 84 (driver_pgsql_set_state): assertion failed: (state == SQL_DB_STATE_BUSY || db->cur_result == NULL) 2012-11-28 10:04:41 dict: Error: Raw backtrace: /usr/local/dovecot-2.1.10/lib/dovecot/libdovecot.so.0(+0x4857a) [0x7f91f511157a] -> /usr/local/dovecot-2.1.10/lib/dovecot/libdovecot.so.0(+0x485c6) [0x7f91f51115c6] -> /usr/local/dovecot-2.1.10/lib/dovecot/libdovecot.so.0(i_error+0) [0x7f91f50e4eaf] -> dovecot2.1/dict() [0x40aa36] -> dovecot2.1/dict() [0x40aa91] -> dovecot2.1/dict() [0x40bed3] -> dovecot2.1/dict() [0x409504] - -> dovecot2.1/dict(sql_db_cache_deinit+0x20) [0x408a60] -> dovecot2.1/dict(main+0x169) [0x405a59] -> /lib/libc.so.6(__libc_start_main+0xfd) [0x7f91f4b5cc8d] -> dovecot2.1/dict() [0x404bb9] 2012-11-28 10:04:41 dict: Fatal: master: service(dict): child 22923 killed with signal 6 (core not dumped) - -- Steffen Kaiser -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQEVAwUBULXbiGoxLS8a3A9mAQI9Ywf/YItPO4fFT70HcuwCkDXgx0Sn7CEyXu2j +1VzOu3R/TMs1rcxYJIvWiei6Nk3wXywzQl84POadJn61Yf2NuT80nMxwBsBbgio e+0oRE9JNVSjtvX5l7kehEdUDQjqRRKyrhWG9KDlpjWidGsYh7pQg0rDtp3UwG57 HuSBMiBAZ9t9sC2DXjn9wT9vweH3gMIhc/K5U0BLF5JG/K8UAKc5QBUgezjIYzvn KP90TJ4RoZ2vnPzmWfeIsjffRBvvC6UUgWmU02e2H9xJxzF32Nix0s8YWi7G91sH Ei057HW5NsKNDtp6B5fYk+xCpC6ucQiwFSr/ZG+uZCAdtTd2qmf60g== =tQYK -----END PGP SIGNATURE-----

[Dovecot] setting mail_home and vacation
by Andreas Meyer 20 Dec '12

20 Dec '12

Hello! dovecot version 2.1.7 I set up vacation with sieve. We have mboxes and maildirs and in dovecot.conf mail_location = mbox:/var/spool/vhosts/%d/dovecotprivate/%n:INBOX=/var/spool/vhosts/%d/%n Error: User archiv(a)xyz.de doesn't have home dir set, disabling duplicate database Dec 19 20:37:03 lda(archiv(a)xyz.de): Error: sieve: sieve script file path ~/.dovecot.sieve is relative to home directory, but home directory is not available. Dec 19 20:37:03 lda(archiv(a)xyz.de): Error: sieve: failed to access user's sieve script ~/.dovecot.sieve (using default script location instead) When I set mail_home = mbox:/var/spool/vhosts/%d/%n:INBOX=/var/spool/vhosts/%d/%n I get this for mboxes in the log: Error: user archiv(a)xyz.de: Relative home directory paths not supported: mbox:/var/spool/vhosts/xyz.de/archiv:INBOX=/var/spool/vhosts/xyz.de/archiv The .dovecot.sieve script of the user seems to be found, a vacation response is sent and the email is stored mail into mailbox 'INBOX' What is wrong?

[Dovecot] Problems trying to add dspam delivery to dovecot LDA to working Postfix/Dovecot server. No passdb.
by Brian Jarrett 20 Dec '12

20 Dec '12

Hello list, I'm really hoping someone can point me in the right direction on this. I set up a server using Postfix with LDAP lookups to Active Directory. Postfix delivers to maildir. Dovecot IMAP and POP are working correctly using PAM Kerberos to authenticate via Active Directory. I want to add spam filtering, so I'm trying to set up Postfix to use dspam which is then supposed to use Dovecot LDA to deliver messages to the mailbox instead of having Postfix deliver to the Maildir. I can't get any deliveries to Dovecot LDA to get past passdb lookup. When I run /usr/lib/dovecot/deliver -f bjarrett(a)garfield16.org -d bjarrett(a)metcalfexcavation.com I get: Dec 19 20:57:55 mxserver2 dovecot: auth: Debug: master in: USER#0111# 011bjarrett(a)metcalfexcavation.com#011service=lda Dec 19 20:57:55 mxserver2 dovecot: auth: Debug: password( bjarrett(a)metcalfexcavation.com) passdb doesn't support credential lookups Dec 19 20:57:55 mxserver2 dovecot: auth: Error: static( bjarrett(a)metcalfexcavation.com) passdb doesn't support lookups, can't verify user's existence Dec 19 20:57:55 mxserver2 dovecot: auth: Debug: master out: FAIL#0111 Dec 19 20:57:55 mxserver2 dovecot: lda: Error: user bjarrett(a)metcalfexcavation.com: Auth USER lookup failed Dec 19 20:57:55 mxserver2 dovecot: lda: Fatal: Internal error occurred. Refer to server log for more information. so it doesn't even look like it's attempting to find the user.

[Dovecot] Maildir hardlinks with sieve
by Benedetto Vassallo 19 Dec '12

19 Dec '12

Hi all, First of all, excuse me for my previous posts (Maildir hardlinks). Today I realized the following issue. Maildir hardlinks works OK on dovecot 2.1.10 without sieve. If set sieve plugin in dovecot-lmtp hardlinks stop working. Is there a way to have both sieve and hardlinks working?

[Dovecot] namespace subscription problem
by Holger Hegmanns 19 Dec '12

19 Dec '12

Hi all, my problem seems to be a cosmetic one (again). According to the docs: subscriptions: "yes" (default) if this namespace should handle its own subscriptions. If "no", then the first parent namespace with subscriptions=yes will handle it. Therefore is no way to create the following scenario: three namespaces (private, shared, public) the private namespace has to handle its own subscriptions the private namespace setup with "prefix = INBOX." the both shared and public namespace setup with "subscriptions = no" cause there is no so called "parent" namespace. Private namespace setup with "prefix = " works fine, but that's not what I want. namespace { type = public separator = . prefix = public. location = maildir:/var/spool/dovecot/vmail/public subscriptions = no } namespace inbox { type = private separator = . prefix = INBOX. inbox = yes } namespace { type = shared separator = . prefix = user.%%u. location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u subscriptions = no list = children } Any chance that the private namespace can subscribe to shared mailboxes with the principals above? ... Few hours later. Added a default namespace without any prefix: namespace { prefix = separator = . hidden = yes subscriptions = yes } Subscriptions works as expected, but when I telnet to dovecot now the LSUB command shows all boxes beneath the INBOX as well as without the prefix: b lsub "" * * LSUB () "." "Sent" * LSUB () "." "Templates" * LSUB () "." "Trash" * LSUB () "." "Drafts" * LSUB () "." "INBOX.Sent" * LSUB () "." "INBOX.Templates" * LSUB () "." "INBOX.Trash" * LSUB () "." "INBOX.Drafts" * LSUB () "." "INBOX.user.bar.Sent" * LSUB () "." "user.bar.Sent" b OK Lsub completed. Completely stuck Holgert

[Dovecot] migration to dovecot pop3
by Rajesh M 19 Dec '12

19 Dec '12

hi i am planning to migrate from qmail pop3 to dovecot pop3 the number of users on the server is large over 5000 also data volume is large - over 3.5 tb -- ie many users several 1000s of emails in their inbox email clients used are outlook / outlook express / windows mail, etc my questions 1) will the migration cause all the emails on the server to re-download 2) can dovecot be configured to allow only one download at a time - pop3 locking with time out setting that can be customized 3) can dovecot pop3 be configured so that it will allow download of emails only of the last say 15 days ie even if the same pop3 user is configure on another machine it will download only messages of the last 15 days 4) has anybody migrated from qmail pop3 to dovecot pop3 successfully without emails being downloaded again thankyou very much in advance rajesh

[Dovecot] Upload / migrate old mails: iPhone shows oldest mails first
by Denny Schierz 19 Dec '12

19 Dec '12

hi, I've got a very strange behavior: I uploaded old mails from a local folder (thunderbird / osx) to my Dovecot (Debian Squeeze) and now, the iphone (ios6) show the oldest mails first. The only thing I can imagine is, that Dovecot got from Thunderbird the newest mails first and last the old mails, so that in the last mdbox are the old one. So, if it is correct, how can I fix it? cu denny
