smtp lastlogin
by Eduardo Ramos 30 Oct '14

30 Oct '14

Hey guys! I've been googling without success. Do anyone know if there is a way to track last login of a smtp authentication? I've tried without success using: service auth { executable = auth lastlogin unix_listener auth-userdb { } unix_listener /var/spool/postfix/private/auth { mode = 0660 group = postfix } } service lastlogin { executable = script-login -d /usr/local/bin/lastlogin.sh unix_listener lastlogin { user = $default_internal_user mode = 0666 } }

[Pigeonhole] Problem compiling latest snapshot
by Bernd Kuhls 29 Oct '14

29 Oct '14

Hi, http://hg.rename-it.nl/dovecot-2.2-pigeonhole/rev/a1e57385b267 added the use of update-version.sh, but this file and is-tagged.py are not included in Pigeonhole, only in Dovecot sourcecode. Therefore pigeonhole- version.h is not generated during compilation leading to a compile error: ../../../../src/lib-sieve/sieve-config.h:8:32: fatal error: pigeonhole- version.h: No such file or directory #include "pigeonhole-version.h" Regards, Bernd

Pigeonhole 0.4.4 error with no sieve rules
by James 29 Oct '14

29 Oct '14

I have built and installed Pigeonhole 0.4.4 with Dovecot 2.2.15. For users with no sieve at all I am getting an error on delivery. Delivery is from exim via lmtp. Syslog: Oct 28 11:03:50 mailhost dovecot: [ID 583609 mail.crit] lmtp(18915): Fatal: master: service(lmtp): child 18915 killed with signal 11 (core not dumped - set service lmtp { drop_priv_before_exec=yes }) There is no global sieve script because there is no global sieve rule. Where an account has sieve rules delivery works as expected. To make it work again I've gone back to 2.2.15 with 0.4.3. James.

Dovecot 2.2.14 and per user \Seen flags
by Thomas Robers 29 Oct '14

29 Oct '14

Hello, I have a Dovecot Installation Version 2.2.14 on CentOS 6.5 with shared folder. UserA shares his INBOX to user UserB. I activated "per user \Seen flags" with location = maildir:%%h/Maildir:INDEX=%h/shared/%%u:CONTROL=%h/shared/%%u:INDEXPVT=%h/shared I think the INDEXPVT setting activates this setting, right? I activated this setting when there were already several accounts in use. Before we used shared \Seen flags. But this setting doesn't work on my system. For example UserB marks several Messages as read in a shared INBOX from UserA and erverything seems alright but then suddenly all seen Messages are marked as unread again and I see the following error message in the log file: Oct 27 14:40:48 mail dovecot: imap(UserB(a)tutech.de): Error: /export/home/imap/UserB(a)tutech.de /shared/.INBOX/dovecot.index.pvt reset, view is now inconsistent Oct 27 14:40:48 mail dovecot: imap(UserB(a)tutech.de): Disconnected: BUG: Unknown internal error in=1020 out=2757 My Dovecot configuration is: root@mail:~# doveconf -n # 2.2.14: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-431.29.2.el6.x86_64 x86_64 CentOS release 6.5 (Final) ext4 auth_master_user_separator = * auth_mechanisms = plain login auth_verbose = yes disable_plaintext_auth = no mail_debug = yes mail_location = maildir:/export/home/imap/%Lu/Maildir mail_plugins = acl zlib managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave duplicate mbox_write_locks = fcntl namespace { hidden = no ignore_on_failure = no inbox = no list = children location = maildir:%%h/Maildir:INDEX=%h/shared/%%u:CONTROL=%h/shared/%%u:INDEXPVT=%h/shared prefix = shared/%%u/ separator = / subscriptions = yes type = shared } namespace inbox { hidden = no inbox = yes list = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = INBOX/ separator = / type = private } passdb { args = /etc/dovecot/master-users driver = passwd-file master = yes } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { acl = vfile:/etc/dovecot/global-acls:cache_secs=300 acl_shared_dict = file:/export/home/shared-db/shared-mailboxes mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename mail_log_fields = uid box msgid size zlib_save = gz zlib_save_level = 6 } protocols = imap pop3 lmtp sieve service auth { unix_listener /var/spool/postfix/private/auth { mode = 0666 } unix_listener auth-userdb { group = vmail mode = 0660 user = vmail } } service imap-login { process_limit = 500 process_min_avail = 20 } service lmtp { inet_listener lmtp { address = 127.0.0.1 port = 24 } } ssl = required ssl_cert = </etc/pki/dovecot/certs/mail.tutech.de.crt_chain ssl_key = </etc/pki/dovecot/private/mail.tutech.de.key ssl_protocols = !SSLv3 !SSLv2 syslog_facility = local6 userdb { args = /etc/dovecot/dovecot-ldap-userdb.conf.ext driver = ldap } protocol lmtp { mail_plugins = acl zlib sieve } protocol imap { mail_plugins = acl zlib imap_zlib imap_acl } I don't know, is there something wrong with my configuration, am I missing sonething?

maildir++ quota support on dovecot
by Mirko ML 28 Oct '14

28 Oct '14

Some information about maildir++ that I have read: http://www.inter7.com/courierimap/README.maildirquota.html http://wiki2.dovecot.org/Quota/Maildir When I have to deliver a message with an MDA I can use dovecot-lda. If I have enabled "quota = maildir:User quota" I am pretty sure that in the mailbox on file system I find a file named "maildirsize" maildirsize on top contain something like this "xxxxxxxxxxS" that specifies the SIZE quota in bytes. LDA could delivery the message only when the SIZE written in mailbox is less than the SIZE defined by mail admin. "Each member of the list consists of an integer followed by a letter, specifying the nature of the quota. Currently defined quota types are 'S' - total size of all messages, and 'C' - the maximum count of messages in the maildir. For example, 10000000S,1000C specifies a quota of 10,000,000 bytes or 1,000 messages, whichever comes first." For this reason the value in bytes defined for the user must have S at the end. At the moment quota-maildir.c contains a control for S or C so I can find this in log: Quota rule: root=User quota mailbox=* bytes=20971520 messages=0 But quota-util.c do not contains a control for C and S, so probably the support of maildir++ format is not complete. Please let me know if I am wrong. -- Ciao Mirko

Namespaces (or another way) to put messages in a different drive
by Paulino Michelazzo 28 Oct '14

28 Oct '14

Hello people, I have a situation where I need to create a mailbox for clients where they put old messages (> 1year) but I would like to create this mailbox in a different disk. I have a server with the mailboxes and a storage mapped using NFS just to create those mailboxes for old messages. I was trying to namespaces but every time that I make the configurations, the authentication system stop and the clients can’t log in. I really don’t know if this is the best approach for my situation (mailbox with old emails in a storage) and, if namespaces can solve it. The infos that I have are: Dovecot version 2.1.7 mailboxes: Namespace configs: namespace { type = private separator = / prefix = #location defaults to mail_location. inbox = yes } namespace { type = private separator / prefix = storage/ location = /mnt/exibstor/%u inbox = no hidden = no list = yes } If someone knows how can I do that, I really appreciate it. Best regards, Paulino Michelazzo
