[Dovecot] Sub-Subfolder from public folders
by Torsten Harenberg 10 Jun '11

10 Jun '11

Dear all, I just moved from an old cyrus instance to a brand new dovecot installation. Everything worked pretty well so far. The only small problem I have is: we have public folders, so I defined namespace { type = public separator = . prefix = public. location = maildir:/var/mail/public:INDEX=%u/public subscriptions = no list = children } And I define ACLs for the folders inside. This works, but the some of these folders have sub-folders and these cannot be seen by (what I have tested is Apple Mail, Thunderbird, Outlook and squirrelmail). File system looks like this: mail# cd /var/mail/public/.icecube-c mail# ls -l .ice* .icecube-hard: total 232 drwxrwxrwx 2 root wheel 512 Jun 9 13:07 cur -rwxrwxrwx 1 root wheel 167 Jun 9 13:07 dovecot-keywords -rwxrwxrwx 1 root wheel 105179 Jun 9 13:07 dovecot-uidlist drwxrwxrwx 2 root wheel 123904 Jun 9 13:07 new drwxrwxrwx 2 root wheel 512 Jun 9 13:07 tmp .icecube-soft: total 2214 drwxrwxrwx 2 root wheel 512 Jun 9 13:06 cur -rwxrwxrwx 1 root wheel 167 Jun 9 13:07 dovecot-keywords -rwxrwxrwx 1 root wheel 1019250 Jun 9 13:07 dovecot-uidlist -rwxrwxrwx 1 root wheel 0 Jun 9 13:06 maildirfolder drwxrwxrwx 2 root wheel 1195008 Jun 9 13:07 new drwxrwxrwx 2 root wheel 512 Jun 9 13:07 tmp mail# ls .icecube-hard .icecube-soft cur dovecot-acl dovecot-keywords dovecot-uidlist new subscriptions tmp Maybe anybody can help with this?

[Dovecot] On-delivery deduplication?
by Xin LI 10 Jun '11

10 Jun '11

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hi, A feature of Cyrus-IMAPd I really missed after migrated to Dovecot is their optional "duplicate suppression", which eliminates duplicate message at deliver time, if their envelope sender, recipient and message-id matches. For example, if one subscribes to a mailing list, and someone hit "Reply All" to reply to him, there will be two different SMTP deliveries, one from the replier's server and one from the mailing list. Is it possible to do the same on latest Dovecot? (Looking at the documentation it seems not?) Or is there some better ways to implement the same functionality? Thanks in advance!

[Dovecot] possible bug leading to lmtp crashes
by Trever L. Adams 10 Jun '11

10 Jun '11

I have been using Samba 4 kerberos and ldap with dovecot. Samba 4 changed a while back (resulting in me asking for help) which requires kerberos auth for ldap lookups. My setup worked perfectly before hand. Before and after were with dovecot-2.0.11 and the after also happens with 2.0.11. The only changes were (in my ldap.conf for dovecot -- changes are new lines starting with *, * is not in the conf, just showing changes): hosts = example.org base = dc=example,dc=org ldap_version = 3 user_attrs = userPrincipalName=user user_filter = (&(objectClass=person)(|(mail=%u)(sAMAccountName=%u)(userPrincipalName=%u))) *dn = MACHINEACCOUNT$(a)EXAMPLE.ORG *sasl_bind = yes *sasl_mech = GSSAPI *sasl_realm = EXAMPLE.ORG *#sasl_authz_id = MACHINEACCOUNT$(a)EXAMPE.ORG # For using doveadm -A: iterate_attrs = userPrincipalName=user iterate_filter = (objectClass=person) in dovecot.conf: import_environment = TZ KRB5CCNAME=/etc/dovecot/krb5.cc With that do any of the following lines from the referenced hg rev set mean I am missing anything on my import_environment variable? Or is it all good? 10.15 +/* <settings checks> */ 10.16 +#ifdef HAVE_SYSTEMD 10.17 +# define ENV_SYSTEMD " LISTEN_PID LISTEN_FDS" 10.18 +#else 10.19 +# define ENV_SYSTEMD "" 10.20 +#endif 10.21 +#ifdef DEBUG 10.22 +# define ENV_GDB " GDB" 10.23 +#else 10.24 +# define ENV_GDB "" 10.25 +#endif 10.26 +/* </settings checks> */ 10.27 + 10.28 static const struct master_settings master_default_settings = { 10.29 .base_dir = PKG_RUNDIR, 10.30 .libexec_dir = PKG_LIBEXECDIR, 10.31 + .import_environment = "TZ" ENV_SYSTEMD ENV_GDB, If I am not missing anything, then there seems to be a problem with kerberos sasl with ldap lookups.

[Dovecot] IMAP Label Updates not showing up across shared account
by Ricardo Branco 09 Jun '11

09 Jun '11

Dovecot 2.0.13 Centos 5.4 x86_64 2.6.18-164.9.1.el5 (on ESXi) OS/Logs on local storage, /home all on NFS server for datastore (NFS Store Centos 5.5 x86_64 2.6.18-194.11.1.el5) Thunderbird 3.1.10 on XP/W7 Desktops We are seeing a werid issue where there is a delay of up to a few mins in seeing label updates on messages. I have confirmed that Thunderbird is sending the update to the server with WireShark, its just additional users connected to the same mailbox do not see them. Marking a message as Seen/Un-Seen happens faster just not labels. If you have a label set when you mark a message as Seen/Un-Seen the other clients then see the update straight away. -- The information contained in or attached to this email is intended only for the use of the individual or entity to which it is addressed.

Hi Doing mail debug I found this dovecot: lmtp(12696, user1(a)domain.tld) Error: o_stream_send_istream(/var/vmail/domain.tld/user1/Maildir/tmp/1307537596.M117043P12696.smtp1) failed: No space left on device dovecot: lmtp(12696, user1(a)domain.tld) Error: o_stream_flush(/var/vmail/domain.tld/user1/Maildir/tmp/1307537596.M117043P12696.smtp1) failed: No space left on device So dovecot write in to a tmp folder inside the user Maildir before definitly copying it to new folder.

Hi I migrated to dovecot 2 and I started using lmtp for mail delivery. But I have found this on my logs "save failed to INBOX: Not enough disk space" . There is enougth space on disk. and I am not using quota plugin on lmtp my lmtp conf is as follow: # ## LMTP specific settings ## # Support proxying to other LMTP/SMTP servers by performing passdb lookups. #lmtp_proxy = no # When recipient address includes the detail (e.g. user+detail), try to save # the mail to the detail mailbox. See also recipient_delimiter and # lda_mailbox_autocreate settings. #lmtp_save_to_detail_mailbox = no protocol lmtp { # Space separated list of plugins to load (default is global mail_plugins). #mail_plugins = $mail_plugins mail_plugins = sieve postmaster_address = admin(a)domain.tld } Any idea please? Thanks

Hi, I try to deliver into specific folders with the "plus addressing", namely: rcpt to:<userid+folder@domain> This works only if the folder exists.
