[Dovecot] moving mail from private inbox to public folder kills the latter
by Tamas Kadar 12 Aug '10

12 Aug '10

Hi I've ran into something rather nasty: if a user moves a mail from its inbox to a public folder, the folder becomes inaccessible for others, because the moved file will have the the permission 600 instead of 777 (or 666) which the rest of the emails have in the folder. How can I change this behavior so when he moves the mail it automatically becomes world-readable? Also why one mail kills the whole folder? Here's the error I get: Error: open(/home/_shared/projects/.Long.Folder/cur/1281535484.M3B5A7P15183Q0.mail_espell_com:2,Sb) failed: Permission denied (euid=1000(ktamas) egid=1000(ktamas) missing +r perm: /home/_shared/projects/.Long.Folder/cur/1281535484.M3B5A7P15183Q0.mail_espell_com:2,Sb, euid is not dir owner) Thanks and best regards Tamas

[Dovecot] Good bye (and thanks for all the fish)

The management decided to switch over to Zimbra so we will no longer be using Dovecot...which served us exceedingly well. May Timo and the Dovecot community prosper. Thanks for all the help from all of you in the years since our switch from UW-IMAP. -- "Grant us, in our direst need, the smallest gifts: the nail of the horseshoe, the pin of the axle, the feather at the pivot point, the pebble at the mountain's peak, the kiss in despair, the one right word.

[Dovecot] TTY=unknown
by Frank van Amsterdam 12 Aug '10

12 Aug '10

I'm wondering if TTY=unknown should be consider as a warning or error. I'm busy perfectioning the organisation's mail server. I want it to run without any warning or error message. ==> /var/log/auth.log <== Aug 12 11:37:15 h1690641 sudo: mail : TTY=unknown ; PWD=/var/spool/postfix ; USER=root ; COMMAND=/usr/lib/dovecot/deliver -f sender(a)domain.com -d receiver Thanks in advance, Frank

[Dovecot] More than one private namespace not possible
by Jan Friedrich 12 Aug '10

12 Aug '10

Hi everyone, Two days ago I migrated from Courier to Dovecot 1.2.13. Everything went smooth until the point I wanted to try some more features of Dovecot. My working configuration contains just the one INBOX. private namespace. Adding any other private namespaces (e.g. SHARE. with the configuration below) produces strange results in Thunderbird 3.0.6 and Evolution 2.28.3: I cannot see the SHARE. namespace but the mail clients create SHARE^^Trunk and other funny things inside the INBOX. namespace (inside die INBOX. Maildir). Changing the name of this private namespace has no effect. Because the devault dovecot.conf tells me I need an default namespace I created one but that did not change anything. In Thunderbird 3.0.6 the namespaces are correctly displayed in the advanced IMAP settings under "private namespaces" but not in the main view. The logs do not show any errors or warnings and the Maildir for the SHARE. namespace is correctly created by Dovecot. System: Ubuntu Hardy with self-compiled Dovecot 1.2.13 with managesieve 0.11.11 patch. SHARE-Namespace: namespace private { separator = . prefix = SHARE. location = maildir:~/shared/Maildir list = yes subscriptions = yes hidden = no inbox = no } Working config (without second private namespace): # 1.2.13: /usr/local/etc/dovecot.conf # OS: Linux 2.6.18-028stab070.2 x86_64 Ubuntu 8.04.4 LTS base_dir: /var/run/dovecot/ protocols: imap imaps managesieve listen(default): *:143 listen(imap): *:143 listen(managesieve): *:2000 ssl_listen(default): *:993 ssl_listen(imap): *:993 ssl_listen(managesieve): ssl_cert_file: /etc/courier/host.pem ssl_key_file: /etc/courier/host.pem 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(managesieve): /usr/local/libexec/dovecot/managesieve-login first_valid_uid: 1 mail_uid: mail mail_gid: mail mail_location: maildir:~/Maildir mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(managesieve): /usr/local/libexec/dovecot/managesieve mail_plugins(default): acl imap_acl mail_plugins(imap): acl imap_acl mail_plugins(managesieve): mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(managesieve): /usr/local/lib/dovecot/managesieve imap_client_workarounds(default): tb-extra-mailbox-sep imap_client_workarounds(imap): tb-extra-mailbox-sep imap_client_workarounds(managesieve): namespace: type: private separator: . prefix: INBOX. location: maildir:~/Maildir inbox: yes list: yes subscriptions: yes lda: postmaster_address: root(a)domain.de mail_plugins: sieve acl mail_plugin_dir: /usr/local/lib/dovecot/lda auth default: passdb: driver: ldap args: /usr/local/etc/dovecot-ldap.conf userdb: driver: prefetch userdb: driver: ldap args: /usr/local/etc/dovecot-ldap.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: mail master: path: /var/run/dovecot/auth-master mode: 384 user: mail plugin: acl: vfile acl_shared_dict: file:/var/lib/dovecot/shared/shared-mailboxes.db sieve: ~/.dovecot.sieve sieve_dir: ~/sieve Regards -- Jan Friedrich jft(a)dev2day.de Bitte senden Sie mir keine Word- oder PowerPoint-Anhänge.

[Dovecot] v2.0.rc5 released
by Timo Sirainen 12 Aug '10

12 Aug '10

http://dovecot.org/releases/2.0/rc/dovecot-2.0.rc5.tar.gz http://dovecot.org/releases/2.0/rc/dovecot-2.0.rc5.tar.gz.sig Unfortunately v2.0.0 has to be delayed a while longer, because I found that there were still problems in plugin hook handling when using more than 2 plugins. Hopefully it's now finally fully fixed, but I'd like to be sure and wait for one more week to see if people can find a problem with some plugin combination. - Using more than 2 plugins could have caused broken behavior (more fixes for this) - Listescape plugin fixes - mbox: Fixed a couple of assert-crashes - mdbox: Fixed potential assert-crash when saving multiple messages in one transaction.

[Dovecot] sessions accounting and monitoring
by Xavier Pons 12 Aug '10

12 Aug '10

Hi, we would have some accounting/monitoring of pop and imap sessions in our dovecot servers, which are the 'best' and fair way to do it? using some post-login scripts, parsing the log file, using netstat ... I know in the 2.0 version exists the doveadm who, but only relates to imap sessions... some recommendations? thanks Xavier
