[Dovecot] v1.1.beta2 - maildir quota calculation problem
by Andrew Pavlenko 01 Oct '07

01 Oct '07

I have a problem with the maildir quota plugin. Any imap operations cause the plugin to recalculate the mailbox size and put the new value in the second line of the maildirsize file, while the third line always contains the size of the latest operation. So the resulting sum is incorrect. Moreover, quota-warning is not working either. Have anybody else met such problem? mail# ./dovecot -n # 1.1.beta2: /usr/local/etc/dovecot.conf ... mail_plugins(default): quota mail_log mail_plugins(imap): quota mail_log mail_plugins(pop3): quota mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 ... plugin: quota: maildir quota_rule: *:storage=10240 quota_warning: storage=75%% /usr/local/etc/quota-warning.sh 75

[Dovecot] Mixed Courier POP3 and Dovecot IMAP environment
by Jan van den Berg 01 Oct '07

01 Oct '07

Hi, Currently we support Courier POP and IMAP for all our users (users can use IMAP as well as POP at the same time). We are thinking about moving to Dovecot; but first moving away from Courier IMAP to Dovecot IMAP (and maybe later also move to Dovecot POP). This would create a mixed environment; after some research I have the following questions. To not break POP3 Courier and still be able to use Dovecot IMAP: - I have to use the namespace prefix in the dovecot.conf file: I read this in the wiki. - "Patch" the source so Dovecot IMAP will look for/use 'courierimapuiddb' instead of 'dovecot-uidlist': otherwise I guess POP3 and IMAP users will have different UID files, right? Is this smart or will this still break the UID file? - "Patch" the source so Dovecot IMAP will look for/use 'courierimapsubscribed' instead of 'subscriptions' of should I just go with the renaming of the files? I'm thinking about patching so the transition can be as transparent as possible: Also if anything might go wrong in production I want to be able to switch back to the 'old' Courier IMAP (without renaming files etc.) Any thoughts on this? Cheers, Jan

[Dovecot] Released v1.1.beta2
by Timo Sirainen 01 Oct '07

01 Oct '07

http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta2.tar.gz http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta2.tar.gz.sig Several bug/crashfixes. deliver now supports -a parameter (see http://wiki.dovecot.org/LDA) which allows Sieve plugin v1.1.2 to use envelope :detail "to" checks. I also did one more API change for mailbox_transaction_commit*(). There's probably something still wrong with SORT command, but other than that I've fixed everything that's been reported.

[Dovecot] Maildir ignore
by Tomas Horacek 01 Oct '07

01 Oct '07

Hello there. I do like Dovecot so far, but ran into problem I cant seem to solve, maybe someone can point me into right direction please. I am running version 1.0.rc15 on CentOS 5 Linux i386 system, ext3 fs. The problem is I cant get the maildir: and :ignore to work together. Here is my SQL query, that includes the Quota field. # cat /etc/dovecot-sql.conf | grep -i quota user_query = SELECT maildir AS home, 901 AS uid, 901 AS gid, CONCAT('maildir:storage=', floor(IF(quota!=0, quota,-1)/1000), ':ignore=Trash') AS quota FROM mailbox WHERE username = '%u' AND active = '1' Even Dovecot agrees it seems correct. # cat /var/log/maillog | grep kaktus | grep quota\= | tail -n1 Sep 30 23:37:33 XXXXXX dovecot: auth(default): master out: USER 5 XXX(a)XXX.cz home=XXX uid=901 gid=901 quota=maildir:storage=1024:ignore=Trash I hope this is the correct way. Looking at IMAP communication with Wireshark, the server seems to ignore my settings. 118 uid copy 22 Trash\r\n 118 NO Quota exceeded\r\n Anyone can help me, please ? Thank you in advance. --- # dovecot -n # /etc/dovecot.conf listen: [*] ssl_ca_file: /etc/postfix/ssl/cacert.pem ssl_cert_file: /etc/postfix/ssl/smtpd.crt ssl_key_file: /etc/postfix/ssl/smtpd.key login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login login_greeting: login_greeting_capability(default): yes login_greeting_capability(imap): yes login_greeting_capability(pop3): no first_valid_uid: 901 last_valid_uid: 901 mail_location: maildir:/srv/mail/%d/%n mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 auth default: mechanisms: plain login cram-md5 digest-md5 apop user: nobody verbose: yes debug: yes passdb: driver: sql args: /etc/dovecot-sql.conf userdb: driver: prefetch userdb: driver: sql args: /etc/dovecot-sql.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: vmail group: vmail
