[Dovecot] Error while set mailQuota=0 with mbox and LDAP backend
by Zhang Huangbin 25 May '08

25 May '08

Hi, all. I have OpenLDAP(+qmail.schema), Dovecot, Postfix installed on RHEL 5.1 (x86_64), and they works fine with mbox format. The problem is if i set 'mailQuota=0' in LDAP, postfix can't send mail to recipient user. But it works fine with 'mailQuota != 0', such as '10240'(10M). What's wrong with my mail server setting? How can i solved this issue? Thanks very much. Bellow is the mail log from /var/log/maillog: ---------------- /var/log/maillog ------------- # mail -s "h" postmaster(a)a.cn < /etc/hosts && tail -0f /var/log/maillog May 23 20:29:35 rh6 postfix/pickup[1608]: 8E8B884949: uid=0 from=<root> May 23 20:29:35 rh6 postfix/cleanup[1896]: 8E8B884949: message-id=<20080524002935.8E8B884949(a)rh6.bibby.org> May 23 20:29:35 rh6 postfix/qmgr[1616]: 8E8B884949: from=<root(a)rh6.bibby.org>, size=467, nrcpt=1 (queue active) May 24 00:29:35 rh6 postfix/smtpd[1901]: connect from localhost.localdomain[127.0.0.1] May 24 00:29:35 rh6 postfix/smtpd[1901]: CFE838494A: client=localhost.localdomain[127.0.0.1] May 23 20:29:35 rh6 postfix/cleanup[1896]: CFE838494A: message-id=<20080524002935.8E8B884949(a)rh6.bibby.org> May 23 20:29:35 rh6 postfix/qmgr[1616]: CFE838494A: from=<root(a)rh6.bibby.org>, size=1076, nrcpt=1 (queue active) May 24 00:29:35 rh6 postfix/smtpd[1901]: disconnect from localhost.localdomain[127.0.0.1] May 24 00:29:35 rh6 postfix/smtp[1898]: 8E8B884949: to=<postmaster(a)a.cn>, relay=127.0.0.1[127.0.0.1]:10024, delay=0.35, delays=0.07/0/0.01/0.27, dsn=2.0.0, status=sent (250 2.0.0 Ok: queued as CFE838494A) May 23 20:29:35 rh6 postfix/qmgr[1616]: 8E8B884949: removed May 23 20:29:35 rh6 postfix/pickup[1608]: E47BA84949: uid=2000 from=<> May 23 20:29:35 rh6 postfix/cleanup[1896]: E47BA84949: message-id=<dovecot-1211588975-866451-0(a)rh6.bibby.org> May 23 20:29:35 rh6 postfix/qmgr[1616]: E47BA84949: from=<>, size=2085, nrcpt=1 (queue active) May 23 20:29:35 rh6 postfix/pipe[1902]: CFE838494A: to=<postmaster(a)a.cn>, relay=dovecot, delay=0.12, delays=0.01/0/0/0.11, dsn=2.0.0, status=sent (delivered via dovecot service) May 23 20:29:35 rh6 postfix/qmgr[1616]: CFE838494A: removed May 24 00:29:36 rh6 postfix/smtpd[1901]: connect from localhost.localdomain[127.0.0.1] May 24 00:29:36 rh6 postfix/smtpd[1901]: 390468494F: client=localhost.localdomain[127.0.0.1] May 23 20:29:36 rh6 postfix/cleanup[1896]: 390468494F: message-id=<dovecot-1211588975-866451-0(a)rh6.bibby.org> May 23 20:29:36 rh6 postfix/qmgr[1616]: 390468494F: from=<>, size=2522, nrcpt=1 (queue active) May 24 00:29:36 rh6 postfix/smtpd[1901]: disconnect from localhost.localdomain[127.0.0.1] May 24 00:29:36 rh6 postfix/smtp[1898]: E47BA84949: to=<root(a)rh6.bibby.org>, relay=127.0.0.1[127.0.0.1]:10024, delay=0.34, delays=0.02/0/0.01/0.31, dsn=2.0.0, status=sent (250 2.0.0 Ok: queued as 390468494F) May 23 20:29:36 rh6 postfix/qmgr[1616]: E47BA84949: removed May 23 20:29:36 rh6 postfix/local[1951]: 390468494F: to=<root(a)rh6.bibby.org>, relay=local, delay=0.04, delays=0.01/0/0/0.03, dsn=4.3.0, status=deferred (temporary failure.

[Dovecot] Auto-subscribe to folders
by Juan Asensio Sánchez 25 May '08

25 May '08

Hi I will use autocreate plugin in a new installation, and client has asked me if the users can be auto-subscribed to certain folders. Example: the users will have an autocreated Junk folder (for SPAM) and we want the users not to be un-subscribed for this folder; so if the user wants to be unsubscribed (from outlook, webmail, etc), there are two options: a) the action is rejected or denied; b) the next time he/she logins, then the folder is autosubscribed again. Could this be done? How? Thanks in advance.

[Dovecot] Domain variable in checkpassword
by sawyer x 25 May '08

25 May '08

Hello everyone I'm using the checkpassword method but I don't get the domain a user inputs. I can't cross check per virtual domains if I'm not getting one, which means it renders all my efforts useless. I've tried sending %d as a variable to my checkpassword script, but I'm just getting %d instead. This is a dump of my information: %ENV = { 'USERNAME_TRANSLATION' => '', 'SYSLOG_FACILITY' => '16', 'CACHE_SIZE' => '0', 'RESTRICT_GID_LAST' => '', 'TCPREMOTEIP' => '213.31.43.3', 'RESTRICT_GID_FIRST' => '', 'AUTH_NAME' => 'default', 'CACHE_TTL' => '3600', 'SERVICE' => 'IMAP', 'USERDB_1_DRIVER' => 'prefetch', 'USERNAME_CHARS' => 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@', 'DOVECOT_MASTER' => '1', 'RESTRICT_SETGID' => '', 'AUTH_WORKER_MAX_COUNT' => '30', 'AUTH_WORKER_PATH' => '/var/run/dovecot/auth-worker.25291', 'PASSDB_2_ARGS' => '/etc/exim/checkp %d', 'USERNAME_FORMAT' => '', 'LOCAL_IP' => '128.177.27.100', 'PASSDB_2_DRIVER' => 'checkpassword', 'PASSDB_1_DRIVER' => 'pam', 'REALMS' => '', 'PROTO' => 'TCP', 'ANONYMOUS_USERNAME' => 'anonymous', 'RESTRICT_SETEXTRAGROUPS' => '', 'TCPLOCALIP' => '128.177.27.100', 'LOG_TO_MASTER' => '1', 'MASTER_USER_SEPARATOR' => '', 'RESTRICT_SETUID' => '', 'REMOTE_IP' => '213.31.43.3', 'RESTRICT_USER' => '', 'DOVECOT_VERSION' => '1.0.rc15', 'MECHANISMS' => 'plain', 'RESTRICT_CHROOT' => '', 'DEFAULT_REALM' => '' }; ARGS: @ARGV = [ '%d', '/usr/libexec/dovecot/checkpassword-reply' ]; Thanks, Sawyer.

[Dovecot] imap-login processes
by Bryan Polk 25 May '08

25 May '08

First, thanks for this great product. We migrated from Courier last week with only small bumps along the way. We have a few hundred active users with a mix of pop3 and imap clients. The server is running on sparc Solaris 9. We're seeing a problem now with the number of "imap-login" processes rising slowly to it's limit and then (understandably) not letting any more logins happen. Legitimate users seem to have no problem logging in until the limit is hit. Another odd thing is that this is not a problem for pop3-login processes, just imap... I've tried changing some obvious things including the passdb from pam to passwd and back again, but here's the current dovecot -n output: # 1.0.13: /opt/dovecot/etc/dovecot.conf protocols: imap imaps pop3 pop3s ssl_cert_file: /opt/dovecot/etc/ssl/certs/dovecot.pem ssl_key_file: /opt/dovecot/etc/ssl/certs/key.pem disable_plaintext_auth: no login_dir: /opt/dovecot/var/run/dovecot/login login_executable(default): /opt/dovecot/libexec/dovecot/imap-login login_executable(imap): /opt/dovecot/libexec/dovecot/imap-login login_executable(pop3): /opt/dovecot/libexec/dovecot/pop3-login login_processes_count: 12 login_max_processes_count: 512 verbose_proctitle: yes mail_location: maildir:~/Maildir mmap_disable: yes mail_executable(default): /opt/dovecot/libexec/dovecot/imap mail_executable(imap): /opt/dovecot/libexec/dovecot/imap mail_executable(pop3): /opt/dovecot/libexec/dovecot/pop3 mail_plugin_dir(default): /opt/dovecot/lib/dovecot/imap mail_plugin_dir(imap): /opt/dovecot/lib/dovecot/imap mail_plugin_dir(pop3): /opt/dovecot/lib/dovecot/pop3 pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv namespace: type: private prefix: INBOX. inbox: yes auth default: verbose: yes passdb: driver: pam userdb: driver: passwd Any ideas or advice?

[Dovecot] Bug [1.1rc5]: Crash during "CPU architecture changed" index upgrade

Hello List, We just migrated from a PPC Xserve to an Intel Xserve.

[Dovecot] Maildir locking by LDA of dovecot
by Mike Grozak 25 May '08

25 May '08

Hi all! First of all, I want ti thank the whole Dovecot community (developers for developing and fast responses, users for populating and responses too). Dovecot is a really good and fast IMAP server - it serves near 3000 in our installation. Now I have a problem and request community's help its resolving;) Dovecot version: 1.0.13, compiled with vpopmail support. I have an account spam(a)domain.com (:-), in which we put all our spam (we gather statistic later). There can be 10 and more delivery attempts in a second to maildir of this account during the spam attacks on our server. The queue of our server can grow up to 20k messages, and all of these messages are sent to spam(a)domain.com.

[Dovecot] Multiple private namespace question
by Troy Engel 24 May '08

24 May '08

(apologies if this has been covered, can't find it on the Wiki/FAQ, etc.) We have a stellar, fantastic, hard working Dovecot 1.0.5 (yes, I need to upgrade) installation running in Courier-IMAP compatibility mode: mail_location = maildir:~/Maildir:INDEX=/var/spool/dovecot/indexes/%1u/%u namespace private { separator = . prefix = INBOX. inbox = yes } A user purchased a Windows Mobile 6 device which is ignoring the namespace (it's the device's bug for sure, other people report it on forums around the 'net) and there's no way on this device to manually set the Prefix; so, his Sent mails are never making it back to the server when replying from the device because of the missing INBOX. issue. Can I add a second hidden namespace with no prefix: namespace private { separator = . prefix = hidden = yes } ...to fix his problem, but without adversely affecting anyone else? The issue that has given me pause is this comment in the config file: "Default namespace is simply done by having a namespace with empty prefix." ..but then there's also: "If namespace is hidden, it's not advertised to clients via NAMESPACE extension or shown in LIST replies." I'm not sure what exactly will happen by adding a hidden namespace with no prefix after an advertised namespace with a prefix; this is a live server, so mucking up the works with a bad config is not an option. :) Anyone have a clue if this is valid/good/correct and Dovecot will play nicely? Many thanks, -te -- Troy Engel | Systems Engineer Fluid, Inc | http://www.fluid.com

[Dovecot] I've moved
by Timo Sirainen 24 May '08

24 May '08

I've moved again. If you need to know my new address, whois imapwiki.org (dovecot.org address is still lagging behind). My living costs also increased some because of this, but hopefully I'll get enough money from Dovecot coding to pay for it. :) I'll try to get back to replying mails within the next few days.
