[Dovecot] Migrate courierimapsubscribed to subscriptions
by Alessio Cecchi 25 Jun '08

25 Jun '08

Hi here's a little trick to migrate from courierimapsubscribed to subscriptions: create a file /usr/local/bin/courier-dovecot-subscribe-migrate like this: #!/bin/sh # WARNING: Be sure to use mail_drop_priv_before_exec=yes, # otherwise the files are created as root! if [ -e ~/Maildir/courierimapsubscribed ] then cat ~/Maildir/courierimapsubscribed | sed -e 's/INBOX\.//' > ~/Maildir/subscriptions mv ~/Maildir/courierimapsubscribed ~/Maildir/courierimapsubscribed-VIA fi # This is for imap, create a similar script for pop3 too exec /usr/libexec/dovecot/imap remember to chmod 755 /usr/local/bin/courier-dovecot-subscribe-migrate after in your dovecot.conf add: mail_drop_priv_before_exec=yes mail_executable=/usr/local/bin/courier-dovecot-subscribe-migrate reload dovecot and now on the first IMAP login (like via webmail) your subscriptions folders will be migrate to dovecot format.

[Dovecot] Maildir and Invalid data in file
by Patryk 25 Jun '08

25 Jun '08

Hello, I'm using dovecot version 1.0.13 on reiserfs on hardware RAID-0, but I'm getting the following error in the logs every time one user tries to access his old mails in the .Sent directory: dovecot: 2008-06-23 15:09:46 Error: IMAP(marek.chajecki): Invalid data in file /var/mail/Maildir/marek.chajecki/.Sent/dovecot-uidlist As a result he fails to get access to the emails in this folder. I've googled a bit and read that deleting the uidlist makes dovecot recreate it, but after some time the same thing happens. It's a new hard drive, so I don't think this is a hard drive fault. Some additional info: this server is being used by about 200 users who get about 100 emails daily each one of them. Config: root@warsaw Maildir # dovecot -n # 1.0.13: /etc/dovecot/dovecot.conf log_path: /var/log/dovecot.log info_log_path: /var/log/dovecot.log log_timestamp: %Y-%m-%d %H:%M:%S ssl_listen: * login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login login_process_per_connection: no login_processes_count: 15 login_max_processes_count: 512 max_mail_processes: 4096 mail_privileged_group: mail mail_location: maildir:/var/mail/Maildir/%u maildir_copy_with_hardlinks: yes auth default: worker_max_count: 100 passdb: driver: pam args: cache_key=%u dovecot userdb: driver: passwd Any help will be appreciated! -- Regards, Patryk Rzadzinski

[Dovecot] Limiting SSL (external) access to certain users ?
by Jakob Curdes 25 Jun '08

25 Jun '08

I am looking for a way to limit outside access to the IMAP server to certain users only. Basic idea is to use two userdbs, one for SSL connections and one "internal" with most users in it. Is there a way to do this without running two dovecot configurations? Thanks for hints, Jakob

[Dovecot] 1 week after full migration to 1.1v
by Raphael Bittencourt S. Costa 24 Jun '08

24 Jun '08

Ehlo all, I've been working on a migration of about 240K users from one server with qmail, courier imap, maildrop and ldap to postfix, dovecot, lda +sieve. Before the migration the server and the storage were always on high load. Before migration: Storage IOPs = 4600 Read average = 2800 Write average = 1800 Storage CPU (Raid5) Crl0 = 50% Crl1 = 50% Server Load = 120 %user = 35 %system = 60 %iowait = 5 %idle = 0 After migration: Storage IOPs = 3000 Read average = 1200 Write average = 1800 Storage CPU (Raid5) Crl0 = 40% Crl1 = 40% Server Load = 25 %user = 10 %system = 27 %iowait = 40 %idle = 23 And now the server responds so quickly to any imap command. Dovecot is now the default imap/pop server here, Thanks Timo. []s, Raphael Costa

[Dovecot] v1.0.13: maildirfolder not being created
by Eduardo M KALINOWSKI 23 Jun '08

23 Jun '08

Hi, I'm using version 1.0.13 of dovecot. I know it's somewhat dated, but that's the latest that Debian etch offers, and I would like to avoid compiling by myself if possible. dovecot is not creating the 'maildirfolder' in folders that are created via IMAP. Looking at the NEWS file, this was implemented in v1.0.rc7, so my version should have that working already. Is there anything else that needs to be done? Here's dovecot -n: # 1.0.13: /etc/dovecot/dovecot.conf log_path: /var/log/dovecot/main.log info_log_path: /var/log/dovecot/info.log log_timestamp: %Y-%m-%d %H:%M:%S ssl_cert_file: /etc/ssl/certs/server.pem ssl_key_file: /etc/ssl/private/server.pem login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_processes_count: 1 first_valid_uid: 100 mail_privileged_group: mail mail_location: maildir:/home/vmail/%d/%n/INBOX:INDEX=/home/vmail/%d/%n/dovecotidx mail_plugins: quota imap_quota auth default: mechanisms: plain login cram-md5 passdb: driver: passwd-file args: /home/vmail/%d/db/passwd passdb: driver: pam userdb: driver: static args: uid=104 gid=8 home=/home/vmail/%d/%n userdb: driver: passwd socket: type: listen client: path: /var/run/dovecot/auth-client mode: 438 plugin: quota: maildir:ignore=Trash -- I want the presidency so bad I can already taste the hors d'oeuvres.

[Dovecot] Testing using namespaces
by Kyle Wheeler 23 Jun '08

23 Jun '08

Hey there, I'm interested in testing out using different storage formats for different folder hierarchies. I *think* this can be achieved using namespaces, but I'm not sure. For example, is it possible to, say, make all directories under INBOX.Archive be stored as mboxes, while everything else is stored as Maildirs? ~Kyle -- May your glass be ever full. May the roof over your head be always strong. May you be in heaven half an hour before the devil knows you're dead. -- Old Irish Toast
