[Dovecot] dovecot & OCFS2 Cluster
by Osvaldo Alvarez Pozo 20 May '11

20 May '11

hi all We have an ocfs2 cluster compose of 4 Debian lenny serveurs wich have access to an ISCSI LUN we have create a partition on this Lun and formated this partition as OCFS2. 2 serveurs does mail delivery (SMTP) and the two other are pop/imap servers. The smtp servers use dovecot LDA to deliver to mailboxes. La version de dovecot is 1.2.13, ldirectord balance conexion to the servers(pop/pops/imap/imaps to the two imap/pop serveurs) (smtp to the two smtp servers). this is a part of my dovecot.conf mail_location = maildir:/var/vmail/%d/%u/Maildir mail_access_groups = mail first_valid_uid = 5000 last_valid_uid = 5000 mail_max_userip_connections = 100 maildir_copy_with_hardlinks = yes disable_plaintext_auth = no dotlock_use_excl=yes mmap_disable = yes protocols = imap imaps pop3 pop3s managesieve protocol imap { mail_plugins = quota imap_quota imap_client_workarounds = outlook-idle delay-newmail } protocol pop3 { mail_plugins = quota pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_uidl_format = %08Xu%08Xv } protocol lda { mail_plugins = quota sieve log_path = /var/log/dovecot-deliver.log info_log_path = /var/log/dovecot-deliver.log } protocol managesieve { managesieve_implementation_string = dovecot } auth default { mechanisms = plain login passdb sql { args = /etc/dovecot/sql.conf } userdb prefetch { } userdb sql { args = /etc/dovecot/sql.conf } user = nobody socket listen { master { path = /var/run/dovecot/auth-master mode = 0660 user = vmail group = mail } client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = mail } We are having severals problems from "cpu stuck for 61 seconds" to "too many connexion". I wonder if there is a configuation type of dovecot when using ocfs2. In tje dovecot site they give advices about how to configure dovecot when using NFS, but not about OCFS2. Somme people say that lda shuld not be used. Any help please? Thanks nebano

[Dovecot] Migrate to new server without raw copy
by Daniel L. Miller 20 May '11

20 May '11

I've setup a new virtual machine to run my mail servers. Dovecot is installed and talking with the LDAP server for the user list. Now the question is how to migrate the data from the old Dovecot to the new. The data is stored in mdbox, with some possible corruption. Accordingly, any form of simple file copy is not the answer - I need the messages to be processed by something and then stored fresh on the new server. I do have NFS access both ways if that does anything. I tried imapsync - but it quickly broke on some of the messages. Is dsync the answer? Or do I use a MUA and drag-n-drop the messages a batch at a time between the servers? -- Daniel

[Dovecot] How to stop mail_executable from cwd to ~home
by Gary Duncan 19 May '11

19 May '11

In our environment home directories are auto-mounted via /home/<user> including on the server provided mail. Within the various mail services though we try to isolate and override with local /mail/home/<user> Works well except that dovecot still wants to cd to the real home triggering a useless and potentially hindering automount when it invokes the imap or pop3 process specified by mail_executable, ie an lsof of the process shows cwd of /home/<user> and the automounted home. It does this even though home is properly overridden within. I suspect this is part of changing to invoke as the user as the *-login process are ok but then they are still running as dovecot. Various recent attempts to explicitly respecify HOME for mail_executable via a wrapper script or using env have been to no avail (as seen below). How can I resolve? And no I don't just want to override /home at the system level. Thanks -- Gary # 1.0.9: /etc/dovecot.conf base_dir: /var/run/dovecot/ 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_ca_file: /etc/ssl/certs/gd_bundle.crt ssl_cert_file: /etc/ssl/certs/engr.uvic.ca.crt ssl_key_file: /etc/ssl/private/engineeringwildcard.key ssl_parameters_regenerate: 24 disable_plaintext_auth: no 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 login_log_format_elements: %u [%r] %c login_process_size: 32 login_processes_count: 8 login_max_processes_count: 150 verbose_proctitle: yes first_valid_uid: 100 default_mail_env: mbox:/mail/home/%u/mail/:INBOX=/mail/boxes/%u:INDEX=/mail/indexes/%u mail_location: mbox:/mail/home/%u/mail/:INBOX=/mail/boxes/%u:INDEX=/mail/indexes/%u mbox_read_locks: fcntl dotlock mbox_write_locks: fcntl dotlock mail_executable(default): /bin/env 'HOME=/mail/home/$USER' /usr/libexec/dovecot/imap mail_executable(imap): /bin/env 'HOME=/mail/home/$USER' /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3-home mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 imap_client_workarounds(default): delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(imap): delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(pop3): outlook-idle pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %v.%u pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): oe-ns-eoh outlook-no-nuls auth default: passdb: driver: pam userdb: driver: passwd args: home=/mail/home/%u plugin: home: /mail/home/%u

[Dovecot] v2.0.13 released
by Timo Sirainen 19 May '11

19 May '11

http://dovecot.org/releases/2.0/dovecot-2.0.13.tar.gz http://dovecot.org/releases/2.0/dovecot-2.0.13.tar.gz.sig I've almost managed to read my email backlog, but there are still some unanswered mails. Feel free to resend if you think I should have answered some of your mails. The most important changes since v2.0.12: + Added "doveadm index" command to add unindexed messages into index/cache. If full text search is enabled, it also adds unindexed messages to the fts database. + added "doveadm director dump" command. + pop3: Added support for showing messages in "POP3 order", which can be different from IMAP message order. This can be useful for migrations from other servers. Implemented it for Maildir as 'O' field in dovecot-uidlist. - doveconf: Fixed a wrong "subsection has ssl=yes" warning. - mdbox purge: Fixed wrong warning about corrupted extrefs. - sdbox: INBOX GUID changed when INBOX was autocreated, leading to trouble with dsync. - script-login binary wasn't actually dropping privileges to the user/group/chroot specified by its service settings. - Fixed potential crashes and other problems when parsing header names that contained NUL characters.

[Dovecot] integrating procmail
by errno 19 May '11

19 May '11

Hello, list members! I'm new to dovecot, and haven't needed to maintain an email server instance for quite some time. I recently got a fairly simple postfix + dovecot installation functional as needed, however I now need to get procmail filtering incoming mail, and after reading various docs and wikis, I find that I'm still having a tough time feeling confident on how best to approach it in the simplest manner. (this is for a small installation.... 10 email accounts, max). Below, I've provide the relevant snippets of my current functional configuration; how best to integrate procmail into the mix? /etc/postfix/main.cf: ... alias_maps = hash:/etc/mail/aliases local_recipient_maps = hash:/etc/postfix/vmailbox, $alias_maps virtual_transport = dovecot virtual_mailbox_domains = $mydomain virtual_mailbox_base = /var/vmail/ virtual_mailbox_maps = hash:/etc/postfix/vmailbox virtual_minimum_uid = 500 virtual_uid_maps = static:501 virtual_gid_maps = static:501 ... /etc/postfix/master.cf: ... dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/libexec/dovecot/deliver -f ${sender} - d ${recipient} ... /etc/dovecot/dovecot.conf: ... mail_location = maildir:~/Maildir protocol lda { sendmail_path = /usr/sbin/sendmail } auth default { mechanisms = plain passdb passwd-file { args = /var/vmail/passwd } userdb static { args = uid=vmail gid=vmail home=/var/vmail/%d/%u } socket listen { master { path = /var/run/dovecot/auth-master mode = 0600 user = vmail group = vmail } } } ... Thankyou for any tips, much appreciated!
