[Dovecot] 1.1 beta 11 - no quota warnings
by adam_jh＠hotmail.com 21 Dec '07

21 Dec '07

Having tried and failed to get 1.0.8 with quota-rewrite to send warnings, I removed the 1.0.8 and installed the latest 1.1 - however I still can't get the warnings! Can someone advise what might be wrong - it must be my configuration?? To compile 1.1 I used ./configure --with-deliver --with-mysql. I've chopped and changed my conf till I'm blue in the face. My dovecot-mysql.conf file does not override the quota, I've enabled the debug and verbose = yes - but they don't mention any quota warnings, just normal delivered logs. What else can I do? The process I use is to add up the maildirsize totals, set a storage figure in the conf which makes the maildirsize just less than 95%, then restart dovecot, send an email - and nothing - no warning is triggered! Any help appreciated - I've spent so long on this now. adam # 1.1.beta11: /usr/local/etc/dovecot.conf protocols: imap imaps pop3 pop3s ssl_disable: yes disable_plaintext_auth: no login_dir: /var/run/dovecot-login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login mail_extra_groups: mail mail_location: maildir:/var/vmail/%d/%n mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota 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 imap_client_workarounds(default): outlook-idle delay-newmail imap_client_workarounds(imap): outlook-idle delay-newmail imap_client_workarounds(pop3): pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: user: nobody verbose: yes debug: yes passdb: driver: sql args: /usr/local/etc/dovecot-mysql.conf userdb: driver: sql args: /usr/local/etc/dovecot-mysql.conf socket: type: listen client: path: /var/spool/postfix/private/auth user: postfix group: mail master: path: /var/run/dovecot/auth-master user: vmail group: mail plugin: quota: maildir quota_rule: *:storage=220000b quota_warning: storage=95%% /usr/local/bin/quota-warning 90

[Dovecot] imap+unix users and pop3+virtual users
by Wendell Turner 21 Dec '07

21 Dec '07

This should be simple, but I'm missing something. My virtual users cannot access their mail. I would like Unix users to get their mail via imap which is deposited in /var/spool/mail/username. (This works.) I would like virtual users to get their mail via pop3 which is deposited in /var/spool/mail/vhosts/example.com/auser/mail/inbox (postfix does in fact put the mail there). Those users can get authenticated via file /var/dovecot/passwd, but cannot retrieve their mail. The log message is shown below. The file/directory is there, but doesn't dovecot see it? Thanks, Wendell -------------------- Info: POP3(auser(a)example.com): mbox: data=/var/spool/mail/vhosts/example.com/auser/mail/:INBOX=/var/mail/auser@e… Info: POP3(auser(a)example.com): mbox: root=/var/spool/mail/vhosts/example.com/auser/mail, index=/var/spool/mail/vhosts/example.com/auser/mail, inbox=/var/mail/auser(a)example.com Info: POP3(auser(a)example.com): Mailbox init failed top=0/0, retr=0/0, del=0/0, size=0 -------------------- /usr/sbin/dovecot -n # 1.0.7: /etc/dovecot.conf log_path: /var/log/dovecot.log info_log_path: /var/log/dovecot-info.log protocols: pop3 imap imaps pop3s ssl_cert_file: /etc/CA/cert.pem ssl_key_file: /etc/CA/key.pem 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 mail_location: mbox:~/mail/:INBOX=/var/mail/%u mail_debug: yes mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 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: verbose: yes debug: yes debug_passwords: yes passdb: driver: pam passdb: driver: passwd-file args: /etc/dovecot/passwd userdb: driver: passwd userdb: driver: static args: uid=vmail gid=vmail home=/var/spool/mail/vhosts/%d/%n

[Dovecot] upgrade to 1.1 and mail location
by lenny＠edpausa.com 21 Dec '07

21 Dec '07

I recently upgraded from 1.0.8 to 1.1-11 the only thing that was changed in the config file was the new syntax for mail location. default_mail_env = mbox:~/:INBOX=~/mbox to mail_location = mbox:~/:INBOX=~/mbox now some imap clients, like squirrellmail and pine have difficulties writting to Sent, Draft and sent-mail folders. In all cases the folders are visible and are present in .subsriptions file( although not seen as subscribed in squirrelmail), but the clients complain that folders already exist when trying to write to them after sending. has anyone run into this ? any suggestions ? thanks a lot.

[Dovecot] v1.1.beta11 quota plugin and dict server
by arvids 21 Dec '07

Hello, when dovecot is started, it prints the following error to the console: ILoading modules from directory: /usr/local/dovecot/lib/dovecot/imap IModule loaded: /usr/local/dovecot/lib/dovecot/imap/lib10_quota_plugin.so IEffective uid=65534, gid=65534, home= Idict quota: user = dump-capability, uri = proxy:/var/run/dovecot/dict-server:quotadict Enet_connect_unix(/var/run/dovecot/dict-server) failed: Connection refused It seems that problem is that dict server is not started yet.

[Dovecot] minor issue - dovecot -n output with 1.1.beta11
by arvids 21 Dec '07

21 Dec '07

Hello, when running diff for 'dovecot -n' outputs from beta10 and beta11(for the same config file), I noticed that 'dovecot -n' beta11 output does not show anymore the following parameters, which are set to non-default values(and which 'dovecot -a' shows): login_processes_count login_max_processes_count first_valid_uid first_valid_gid cache_size cache_ttl cache_negative_ttl mode(from auth default section) And by the way, parameters from lda section are not showed both with -a and -n. But it is so already for a long time, so I assume that it is OK :) Regards, Arvids

I have just installed my mail server on a Ubuntu Linux V.7.10 box with sendmail and dovecot imap from the Ubuntu packages. Each time the machines boots, I get the following messages: Starting mail server: dovecotWarning: Fixing permissions of /var/run/dovecot to be world readable Warning: Corrected permissions for login directory /var/run/dovecot/login After the boot the permissions visible are: drwxr-xr-x root root /var/run/dovecot drwxr-x--- root dovecot /var/run/dovecot/login What permissions do I need to set so that the warnings do not appear?

[Dovecot] Dirsize quotas with 1.1beta9
by Dean Brooks 21 Dec '07

21 Dec '07

Hi, Anyone able to get 'dirsize' quotas to work properly under 1.1beta9? I can get them to reflect the size of the INBOX properly, but it never seems to be adding up the size of the files in the folder directory itself. I'll keep hammering away at it if others are able to use dirsize with no problems, but wanted to check first. -- Dean Brooks dean(a)iglou.com

[Dovecot] Security hole #4: Specific LDAP + auth cache configuration may mix up user logins
by Timo Sirainen 21 Dec '07

21 Dec '07

Somehow I doubt there are any Dovecot setups left that unknowingly have this problem, but it still counts as a security hole. The possibility to cause this problem exists in Dovecot v1.0.rc11 and later. If you use: 1. passdb ldap with settings: - auth_bind = yes - auth_bind_userdn = no - base containing %variables required for unique user identification, e.g. base = dc=%d,dc=org - pass_filter not containing all %variables required for unique user identification - pass_attrs returning user-specific settings, such as user's home directory 2. userdb prefetch 3. auth_cache_size non-zero (0 is default) If two users with the same password and same pass_filter variables log in within auth_cache_ttl seconds (1h by default), the second user may get logged in with the first user's cached pass_attrs. For example if pass_attrs contained the user's home/mail directory, this would mean that the second user will be accessing the first user's mails. You most likely would have noticed this already by wondering why logins keep failing, unless pass_filter used also some %variables that most of the time uniquely identifies the user. For example %r (remote IP address) or %n (username without domain). You can fix this by upgrading to v1.0.10 (to be released soon), or using this patch: http://hg.dovecot.org/dovecot-1.0/raw-rev/2cedab21cd6d
