[Dovecot] migrate machines and upgrade
by Donny Brooks 08 Oct '10

08 Oct '10

I am about to be migrating mail servers and have a few questions. First a little background: Old mail server: Fedora 11 dovecot-1.2.11-3.fc11.x86_64 installed from yum repo mbox mail format OpenLDAP authentication 250+ users New mail server: Fedora 13 dovecot-2.0.1-1_118.fc13.x86_64 installed from atrpm rpm file Maildir mail format OpenLDAP authentication 250+ users I plan to use dsync on the new machine to migrate the mail off the old machine and mbox format to the new machine and Maildir. I think I read where I can do the migration without interfering with normal mail delivery and then when i get ready to do the final move I just kill dovecot on the old machine, dsync once more, and start the service on the new machine. What would be the best way to accomplish this? And as for the configuration changed between 1.2.11 and 2.0.1, where to start? I see there is now a conf.d directory for 2.0.1. How will this tie in to the 1.2.11 config? Any pointers there? Other option is to move the mbox mail as it sits to the new machine, install 1.2.X branch dovecot on new machine, and let the convert plugin do all the work. However I like the idea of the dsync doing the sync with minimal downtime. Thanks in advance. -- Donny B.

[Dovecot] pop3-login no longer segfaults with gcc4.5.2 and gold :)

Hello, I reported a while back that it wasn't possible to compile the whole of Dovecot using gcc 4.5.2 and the new gold linker, but it's now working with recent snapshots of both binutils and GCC. Cheers, Olivier

[Dovecot] Significant performance problems
by Chris Hobbs 07 Oct '10

07 Oct '10

Hi all, I'm sure my issues are a result of misconfiguration, but I'm hoping someone can point me in the right direction. I'm getting pressure to move us back to GroupWise, which I desperately want to avoid :-/ We're running dovecot 1.2.9 on Ubuntu 10.4 LTS+postfix. The server is a VM with 1 vCPU and 4GB of RAM. We serve about 10,000 users with anywhere from 500-1000 logged in at any one time. Messages are stored in Maildir format on two NFS servers (one for staff, the other for students). Today I implemented the "High performance" setup described here: http://wiki.dovecot.org/NFS (mainly moving indexes off of NFS, since I'm only using the one server). I also added imapproxy to our webmail client server (SOGo). The vast majority of our users come in over the web. We currently see load averages spiking into the 20-30 range. When this happens, service crawls to a near standstill, and ultimately the SOGo client starts crashing out. I'm wondering if anything jumps out at anybody here - feel free to mock if/when you find an obvious configuration problem. I just want it to work :-) dovecot -n # 1.2.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-25-server x86_64 Ubuntu 10.04.1 LTS log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s managesieve listen(default): * listen(imap): * listen(pop3): * listen(managesieve): *:2000 ssl_cert_file: /etc/dovecot/certs/mail_nhusd_k12_ca_us.crt ssl_key_file: /etc/dovecot/certs/mail_nhusd_k12_ca_us.key disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login login_executable(managesieve): /usr/lib/dovecot/managesieve-login login_process_per_connection: no login_process_size: 512 login_processes_count: 20 login_max_processes_count: 3000 login_max_connections: 64 max_mail_processes: 2048 mail_max_userip_connections(default): 20 mail_max_userip_connections(imap): 20 mail_max_userip_connections(pop3): 10 mail_max_userip_connections(managesieve): 10 mail_access_groups: staffmailusers mail_privileged_group: dovecot mail_uid: mail mail_gid: 502 mail_location: maildir:~/Maildir:INDEX=/var/indexes/%u mail_nfs_storage: yes mbox_write_locks: fcntl dotlock mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_executable(managesieve): /usr/lib/dovecot/managesieve mail_plugins(default): acl imap_acl quota imap_quota expire mail_plugins(imap): acl imap_acl quota imap_quota expire mail_plugins(pop3): mail_plugins(managesieve): mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 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=~/Maildir/shared/%%u list: children lda: deliver_log_format: %$ -- FROM=%f SUBJECT=%s mail_plugins: cmusieve acl expire log_path: info_log_path: syslog_facility: mail postmaster_address:postmaster@nhusd.k12.ca.us hostname: mail.nhusd.k12.ca.us auth_socket_path: /var/run/dovecot/auth-master auth default: passdb: driver: pam passdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf userdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf socket: type: listen master: path: /var/run/dovecot/auth-master mode: 384 plugin: quota: maildir:User quota quota_rule: *:storage=9G quota_rule2: Trash:storage=200M acl: vfile acl_shared_dict:file:/home/staff/dovecot/shared-mailboxes expire: Trash 7 Trash/* 7 Spam 30 expire_dict: proxy::expire sieve: ~/.dovecot.sieve sieve_dir: ~/sieve sieve_extensions: +imapflags dict: expire: mysql:/etc/dovecot/dovecot-dict-expire.conf -- Chris Hobbs Director, Technology New Haven Unified School District -- This message was scanned by ESVA and is believed to be clean.

[Dovecot] And again... too many open files
by Joseba Torre 07 Oct '10

07 Oct '10

Hi! Two days ago I upgraded to 1.2.15, and again I the warning "Warning: fd limit 1024 is lower than what Dovecot can use under full load" reappeared. It's a bit weird, because my actual limits are higher. From /etc/security/limits.conf * soft nofile 4096 * hard nofile 8192 root soft nofile 4096 root hard nofile 8192 dovecot soft nofile 4096 dovecot hard nofile 8192 I added the * lines to avoid problems if a new user was involved, and finally supposed it was a bug in the detection process. Today, as expected, dovecot was not responding with the famous "Too many open files" error. Has something changed? Is there some way to know which is the maximum number of files that can be open? Is there some parameter I can change to avoid this? Here's my dovecot -n # 1.2.15: /usr/local/etc/dovecot.conf # OS: Linux 2.6.18-164.11.1.el5 x86_64 Red Hat Enterprise Linux Server release 5.4 (Tikanga) syslog_facility: local1 protocols: imap imaps pop3 pop3s listen(default): *:143 listen(imap): *:143 listen(pop3): *:110 ssl_listen(default): *:993 ssl_listen(imap): *:993 ssl_listen(pop3): *:995 ssl_cert_file: /usr/share/ssl/certs/imapd.pem ssl_key_file: /usr/share/ssl/certs/imapd.pem disable_plaintext_auth: no login_dir: /usr/local/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 login_process_per_connection: no login_process_size: 256 login_processes_count: 16 login_max_processes_count: 256 login_max_connections: 512 max_mail_processes: 2048 first_valid_uid: 100 mail_location: maildir:~/Maildir:INDEX=/var/dovecot/%u:CONTROL=/var/dovecot nas/%u/control mail_nfs_storage: yes lock_method: dotlock 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 pop3_uidl_format(default): %08Xu%08Xv pop3_uidl_format(imap): %08Xu%08Xv pop3_uidl_format(pop3): %v.%u auth default: cache_size: 1000 cache_ttl: 6000 master_user_separator: * debug: yes passdb: driver: passwd-file args: /usr/local/etc/bloqueados deny: yes passdb: driver: ldap args: /usr/local/etc/dovecot-ldap.conf passdb: driver: passwd-file args: /usr/local/etc/shadow passdb: driver: pam passdb: driver: passwd-file args: /usr/local/etc/dovecot-master.conf master: yes userdb: driver: prefetch userdb: driver: passwd-file args: /usr/local/etc/passwd userdb: driver: ldap args: /usr/local/etc/dovecot-ldap.conf socket: type: listen master: path: /var/run/dovecot/auth-master mode: 384 plugin: quota: fs -- Joseba Torre.

[Dovecot] dovecot-1.2.12 core
by Thomas Hummel 07 Oct '10

07 Oct '10

Hi Timo, just to report that . dovecot-1.2.12 which ran fine for several month . on FreeBSD 7.2-STABLE (/usr/obj/usr/src/sys/GENERIC amd64) . using Maildir (mailboxes, control and indexes on NFS) has crashed this morning on our server. I found nothing special in the logfile. Attached are dovecot -n output and a gdb backtrace of the core file. Thanks -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau
