dovecot-2.2.21 問い合わせ fts_autoindex - index-worker problem Hello List, I installed dovecot-2.2.21 on CentOS 6.7. I use ldap for userdb to separate an e-mail address and the user. Index to apache solr failed in fts_authindex when I received an email after setting. The error message is "indexer-worker: Error: User 0029(a)09.jp lookup failed: Unknown user" Is there any solution? This is current conf -------------------------------------------- # cat /etc/dovecot/conf.d/auth-ldap.conf.ext userdb { driver = ldap default_fields = uid=dovecot gid=dovecot home=/var/dovecot/%Ld/%Ln args = /etc/dovecot/dovecot-ldap.conf.ext } -------------------------------------------- #

Re-starting replication after a long disconnect
by John Krug 30 Jan '16

30 Jan '16

Using Dovecot 2.2.15.8 We use dsync as shown at http://wiki.dovecot.org/Replication <http://wiki.dovecot.org/Replication> to have a second copy of our mail store. Users connect to one server and the other is considered a secondary, and is there “just in case”. If one-way backup/sync would make more sense, I would consider that, but at the time we set it up (October 2013), I recall there was some issue with one-way not being as reliable. We had some problems with the secondary mail server and had to take it off line for while. Now that the mail on that server is stale, what is the best way of starting over? When I simply turned it back on after a lengthy break (weeks), some users were reporting deleted messages showing up in their inboxes. I know dsync is master/master and uses index files, but I am not certain of the details and whether this behavior is completely unexpected or not. The laundry list: What are the f and R flags for sync? http://wiki2.dovecot.org/Tools/Doveadm/Sync Use doveadm backup to get the initial data over to the seconday? Can the server be in use while I do backup? Do I need to wipe the secondary and start over?

Setting Recent Flag on New Messages?
by Haravikk 29 Jan '16

29 Jan '16

So I’m looking at setting up some house-keeping for my dovecot mailboxes, specifically deleting messages in trash, spam etc., by deleting Seen messages older than X days. In order to protect against the edge case of a user reading a message right before the deletion task however I’d like to do something like the following: doveadm expunge -A OLD SEEN BEFORE 7d MAILBOX Trash doveadm flags -A remove '\Recent' SEEN BEFORE 7d MAILBOX Trash (except I’m actually doing this per-user with a script and per-user settings for flexibility, but you get the idea) Basically the expunge step only deletes messages without the Recent flag (and which haven’t been marked as unseen again). It then removes this flag from messages which have been seen, so that they will be deleted next time the expunge command runs. In other words, if this command runs once a day, there will be a minimum delay of 24 hours between a message being seen, and then being deleted. However I can’t for the life of me figure out how to set the Recent flag except via doveadm flags. While I could periodically run doveadm -A flags add ‘\Recent’ SEEN or such this doesn’t seem like a great way to do it (adding the flag after the messages are stored), really I’d rather do it as they arrive. I’ve tried sieve, but it can’t set this flag. Have I managed to completely miss an option for setting this when new messages arrive?

Dovecot (director, lmtp) IPv4/IPv6?
by Andrey Fesenko 29 Jan '16

29 Jan '16

Hello, I'm build system with two director/proxy and dual stack network (or IPv6-only local services) http://wiki2.dovecot.org/Director say "This also means that a single director ring must use either IPv4 or IPv6 addresses, but not both at the same time." OK All servers have 2 interface (public and local network), and all dual stack IPv4/IPv6, imap/pop (mail) and lmtp (mx) proxy run in dedicated server. If network IPv4-only this work fine IPv6-only or IPv4/IPv6 configs not work (on mail director) dovecot-2.2.10-5.el7, CentOS Linux release 7.2.1511 (Core) My configs contain Directors listen = IPv4-public1, IPv4-local1, IPv6-public1, IPv6-local1 director_servers = IPv6-local1 IPv6-local2 director_mail_servers = IPv4-public3 IPv4-local3 IPv6-public3 IPv6-local3 service lmtp { client_limit = 5 executable = lmtp -L idle_kill = 0 process_limit = 0 process_min_avail = 0 protocol = lmtp service_count = 0 inet_listener lmtp { address = IPv6-local1 IPv4-local1 port = 24 } } # 20-lmtp lmtp_proxy = yes service director { unix_listener login/director { mode = 0666 } fifo_listener login/proxy-notify { mode = 0600 } unix_listener director-userdb { mode = 0600 } inet_listener { address = IPv6-local1 port = 9090 } } Without line "address =" in service, all services start all listen.

Correct Way to Run expunge for All?
by Haravikk 29 Jan '16

29 Jan '16

So as part of my daily mailbox maintenance I have the following command: doveadm expunge -A DELETED i.e- I’m only expunging messages that have been specifically marked as deleted. I also only do this *after* running doveadm purge, as this means that there is at least a 24 hour window between a message being marked as deleted, and it being gone forever. However I get the following error message: Fatal: expunge: To avoid accidents, search query must contain MAILBOX in all search branches While I can see the logic in this, it isn’t an accidental use of this command, so who do I force it to proceed? Going forward I’d like to recommend that expunge -A DELETED should be allowed, as it doesn’t seem like an especially dangerous form of the command, particularly with mdboxes where the messages won’t be removed until the purge step. Either that or there should be a flag to force the command when you know it isn’t an accident; anyone adding this to all their queries deserves the damage they inflict =)

Maildir to mdbox conersion size issue
by Petr Bousek 28 Jan '16

28 Jan '16

Hello, I have issue with dovecot 2.2.13 I want to change all Maildirs to mdbox format and I do it per partes, so I change mail_location for user (in sql), than I use doveadm sync -u user path_to_maildir and everything works mostly fine. But now I found that when I migrate quite huge Maildir (about 24G of mails) to mdbox, after sync the final mdbox is twice as big as source Maildir (48GB). I tried to find duplicities, but didn't find any. Is there any reason why mdbox consume so much data? Or I do something wrong? Does somebody have same experience? Thanks Petr

dovecot-2.2.10-5.el7, CentOS Linux release 7.2.1511 (Core) Users stored in LDAP, backend name set his hostname (need for TLS on backend) auth: Debug: passdb out: PASS 1 user=mail proxy=yes host=backend starttls=yes hostip=IPv6-public how algorithm choice IP for hostip, and whether it is possible to implement it repeated request? Now I'm understand the following algorithm, DNS IPv6, /etc/hosts IPv4 single not alternative resolution. If my backend have only local address this FAIL
