[Dovecot] Pre imap-session scripting
by azurIt 02 Nov '13

02 Nov '13

Hi, is it possible to run a script right after the IMAP/POP3 session was started? I know about post-login scripting but this is probably not what i'm looking for. I need to run a script which will know PID of process running IMAP session (so it must be already started). Thank you. azur

[Dovecot] Broken files?
by LuKreme 02 Nov '13

02 Nov '13

Getting a lot of these error for two specific mailboxes. They repeat many times a day, usually within less than 5 minutes. mail dovecot: imap(kremels): Error: Broken file /home/kremels/Maildir/.zz.x-tech.2010/dovecot-uidlist line 2: Invalid extended fields: : $ cat .zz.x-tech.2010/dovecot-uidlist 3 V1263241007 N56581 G11fe2118db236952f984010021d1a38d OI tried deleting the files that generated the errors, but they were recreated and the errors returned. (I’m using dovecot2 and Maildir) -- Death was familiar with the concept of the eternal, ever-renewed hero, the champion with a thousand faces. He'd refrained from commenting.

Maybe it will start working if you configure Mutt set spoolfile=imap://steve@vmail-s/ (Just guessing -- I don't use Mutt.) Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] Shared namespace, separator, username and dots.
by Marcio Merlone 02 Nov '13

02 Nov '13

Hi folks, I run a legacy mailserver that i had replaced courier-imap for dovecot 1.2. Everything is fine except for shared namespace. Maildir structure has been created using dot '.' as folder separator. It happens that all our users are created as name.surname as default. So when I want to select a shared folder, MUA end up with the following IMAP command: select shared.jhon.doe.folder.subfolder Obviously I took ages to figure why it won't work since it takes 'doe' as a folder and not a username part. When sharing a folder from 'sales' user, for example, it works fine. What do you suggest to make shared folders work for all without rebuilding hundreds of maildirs to change folder separator from '.' to '/'? Thanks for any hint. # 1.2.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-52-server x86_64 Ubuntu 10.04.4 LTS log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps managesieve ssl_listen: * disable_plaintext_auth: no verbose_ssl: yes login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(managesieve): /usr/lib/dovecot/managesieve-login login_process_per_connection: no login_max_processes_count: 1024 max_mail_processes: 1024 mail_max_userip_connections(default): 20 mail_max_userip_connections(imap): 20 mail_max_userip_connections(managesieve): 10 first_valid_gid: 0 mail_privileged_group: mail mail_location: maildir:~/Maildir:INDEX=/var/cache/dovecot/%n fsync_disable: yes maildir_very_dirty_syncs: yes mbox_write_locks: fcntl dotlock mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(managesieve): /usr/lib/dovecot/managesieve mail_plugins(default): quota imap_quota acl imap_acl mail_plugins(imap): quota imap_quota acl imap_acl mail_plugins(managesieve): mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(managesieve): /usr/lib/dovecot/modules/managesieve namespace: type: private separator: . inbox: yes list: yes subscriptions: yes namespace: type: shared separator: . prefix: shared.%%u. location: maildir:%%h/Maildir:INDEX=%u/Maildir/shared/%%u list: children subscriptions: yes lda: postmaster_address: postmaster(a)a1.ind.br mail_plugins: quota sieve acl quota_full_tempfail: yes auth_socket_path: /var/run/dovecot/auth-master fsync_disable: no auth default: mechanisms: plain login master_user_separator: * passdb: driver: pam args: session=yes blocking=yes dovecot passdb: driver: passwd-file args: /etc/dovecot/passwd.masterusers pass: yes master: yes userdb: driver: nss args: service=ldap blocking=yes socket: type: listen client: path: /var/spool/postfix/private/dovecot mode: 436 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 438 plugin: sieve: ~/.dovecot.sieve acl: vfile acl_shared_dict: proxy::acl dict: acl: mysql:/etc/dovecot/acl-dict-sql.conf -- *Marcio Merlone* TI - Administrador de redes *A1 Engenharia - Unidade Corporativa* Fone: +55 41 3616-3797 Cel: +55 41 9689-0036 http://www.a1.ind.br/ <http://www.a1.ind.br>

[Dovecot] doveadm can't import his own mdboxes
by Peer Heinlein 02 Nov '13

02 Nov '13

We're running Dovecot 2.1.17 on Debian: # 2.1.17 (9efbc0731929): /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-042stab078.27.debug i686 Debian 7.1 simfs and we're having this namespace configuration: mail_location = mdbox:/var/mail/%Ld/%Ln/mdbox namespace inbox { disabled = no hidden = no ignore_on_failure = no inbox = yes list = yes location = prefix = separator = . subscriptions = yes type = private } As you can see, our namespace seperator is "." and not "/": a LIST "" "*" * LIST (\HasChildren) "." INBOX.test * LIST (\HasNoChildren) "." INBOX.test.huhu * LIST (\HasNoChildren \Trash) "." Trash * LIST (\HasChildren) "." INBOX a OK List completed. The problem is, that doveadm isn't able to import his own mdbox-directory: 1) delete the whole mdbox folder # rm -rf mdbox 2) create the new mdbox folder and create some subfolders in it # doveadm mailbox create -u max.muster INBOX.test # doveadm mailbox create -u max.muster INBOX.test.huhu 3) put a mail into a subfolder 4) try to re-import the whole mdbox: it doesn't work # doveadm import -u max.muster mdbox:mdbox BACKUP all doveadm(max.muster): Error: Couldn't create mailbox BACKUP.INBOX/test/huhu: Character not allowed in mailbox name: '/' Looks like there's something wrong in the namespace or like doveadm is working with a hardcoded internal namespace...

[Dovecot] Configuring SPECIAL-USE Dovecot 2.0.9
by Keith Mountifield 01 Nov '13

01 Nov '13

Hi All, I'm trying to configure Dovecot 2.0.9 to support Outlook 2013. As I understand it, I need to configure XLIST. I have added imap_capability = +XLIST to 20-imap.conf When I try to query the IMAP folders I get an error "An IMAP command Failed". Looking at the logs I get XLIST Command not found. I can only assume that I'm missing something in the configuration. Any help would be greatly appreciated Thanks Keith

[Dovecot] init script as provided http://wiki2.dovecot.org/DovecotInit
by Jess Portnoy 01 Nov '13

01 Nov '13

Hello list, I would add: # dovecot Startup script for the dovecot server # # chkconfig: - # processname: dovecot # config: /path/to/config # pidfile: /path/to/pid So that it supports the chkconfig used by RHEL and clones too. Also, maybe it should be installed by the Makefile's install target? it could then also set: DAEMON=/path/to/dovecot/daemon instead of: DAEMON=/usr/local/sbin/dovecot Cause naturally, it will know the prefix chosen. May the source be with you, Jess Portnoy

[Dovecot] Logging in to a virtual users Maildir
by Steve Downes 01 Nov '13

01 Nov '13

Trying to set up a mailserver to run exim4, dovecot2, (clamav procmail or similar not yet installed) on a virtual machine & access it from various hosts mostly using Mutt. So far no attempt at encryption although there are some pem files from a previous attempt & some evidence from the mutt debug file they may be being used . So far I have attempted to set up dovecot to by accessed by MUAs only & tried to access it from Mutt on on the mailserver virtual machine & on another on locally networked machine (no networking problems). When I open a local mutt I get the following:- 1) could not connect to vmail-s (connection refused) (vmail-s is the mailserver host) 2) mutt then opens, with a blank message screen 3) from mutt I then put C (open mailbox ? for list) & ?. 4) I then get a file list for the mailbox including all dovecot files but no mailbox files except cur. new, & tmp 5) if enter on ../ I get (presumably) /home/vmail/users/steve/ showing Maildir as the 2nd line 6) select Maildir gives me my inbox but continuing the process does not give me acces to any other folders. The files in my mailbox are from my previous version of Dovecot (V1*) but I have previously tried to start anew set of mailboxes with similar results. I enclose below:- my Dovecot.conf file My muttrc file a .muttdebug0 file Dovecot log files show nothing but Dovecot stop/start lines. Any pointers please?
