FTS solr info
by Brad Koehn 11 Dec '16

11 Dec '16

Are there updated instructions on setting up FTS with solr? I’m in the midst of upgrading my site and the links don’t appear to work or be applicable to current versions of solr. I grabbed 6.3.0 from apache and the instructions are no longer working, e.g., there’s no `solr/conf/schema.xml` file to replace; the `start.jar` has moved, etc. Just wondering if there’s somewhere else I should look, or if I should just hack it together on my own. Thanks! Brad Koehn

doveadm-server uses 100% cpu and never finishes, dsync backup also never finishes
by Patrick van Zweden 09 Dec '16

09 Dec '16

Hi Guys, I have a quite interesting problem. I have two servers that replicate to each-other. Suddenly one of the accounts is starting to eat a very large amount of disk space on, what basically is the replica for this account. doveadm-server seems to hang and keeps on filling the disk. I came across this message in the logs: Dec 8 07:36:40 <server> dovecot: dsync-server(<account>): Fatal: pool_system_malloc(6291528): Out of memory Dec 8 07:36:40 <server> dovecot: dsync-server(<account>): Fatal: master: service(doveadm): child 883 returned error 83 (Out of memory (service doveadm { vsz_limit=256 MB }, you may need to increase it) - set DEBUG_OUTOFMEM=1 environment to get core dump) I’ve increased the vsz_limit to 5G so it has stopped complaining. Only… the process never seems to finish. I’ve tried to export the mailbox using dsync: dsync -Dv backup -u 'xxxxx' sdbox:/tmp/patrick_export/ However this process never finishes either. It looks like it stays in one of the mailboxes and keeps on trying to copy messages. Format of the mailbox is sdbox Version of dovecot on all servers: 2.2.9 Any pointers for solving this problem? Kind regards, Patrick -- Patrick van Zweden

doveadm

Hello list, I'm interested in setting up dovecot replication but when I run the command doveadm user '*', which is necessary as indicated here: http://wiki2.dovecot.org/Replication, I get the following output: Error: User listing returned failure Fatal: user listing failed It also indicates the following on the wiki2: "Make sure that user listing is configured for your userdb, this is required by replication to find the list of users that are periodically replicated" I use a vpopmail backup so the question is how do I "Make sure that user listing is configured for...userdb"? This is my userdb settings for vpopmail: userdb { args = cache_key=%u quota_template=quota_rule=*:backend=%q driver = vpopmail } Thank-you Eric

Correct user for replication
by John Fawcett 08 Dec '16

08 Dec '16

Hi I've set up replication with the settings below. With these settings, aggregator runs as user dovecot and replicator as user root. Are those the recommended settings or should I change them, in particular for replicator which is running as a privileged user? service aggregator { fifo_listener replication-notify-fifo { mode = 0666 user = vmail } unix_listener replication-notify { mode = 0666 user = vmail } } service replicator { unix_listener replicator-doveadm { mode = 0660 group = mail } } service doveadm { inet_listener { port = 999 ssl = yes } } ssl_client_ca_file = /etc/pki/tls/cert.pem doveadm_password = secret plugin { mail_replica = tcps:hostname.domainname.tld:999 } thanks John

Migrate from dovecot 1.1 to 2.2 Maildir to 2.2 mdbox
by Daniel Betz 08 Dec '16

08 Dec '16

Hello list, im am trying to migrate customer mails via dsync from an old dovecot 1.1 setup to an new installed dovecot 2.2.25 setup with mdbox. Upgrading the old dovecot 1.1 to 2.2 with Maildir isnt an problem and the replication to the new setup works well too. The only problem now is, that the POP3 UIDL are completely wrong on the target setup. Im using for Maildir pop3_uidl_format = %f With mdbox i cant use it anymore. But what do i need for mdbox ? Or is there an way to migrate the POP3 uidl list to the mdbox ? I could live with it, when i were able to mark the mails older 14 days as read. Is there an way to do this on many mailboxes ? I have read in Release News from 2.2.26 that there are some fixes with POP3 UIDL .. what is it in detail and could it help me ? Hop you can point me to the right direction.

Dovecot: Mails flagged as read get flagged as unread
by plataleas 07 Dec '16

07 Dec '16

Hi all We experience some unexpected behavior with dovecot. It happens that emails marked as read get marked as unread (MUA is Thunderbird on port 143). Unfortunately this happens randomly, reproducing this issue is difficult. We could not find any pattern, it happens rarely. We are running dovecot version 2.2.24 on Debian Jessie (backports repository). /root@dovecot01:~# dovecot --version// //2.2.24 (a82c823)/ Our Setup: /ha-proxy01 -> dovecot-proxy01 (proxy=yes) -> dovecot01 (proxy=no) * IP is used for multiple services (ports). We use the haproxy to send traffic on different ports to different servers. / Below the configuration (IMAPC is active for migration purposes). Do you have any recommendations where we could focus for troubleshooting? I found some posts about mbox_lazy_writes causing similar issues. However we use mdbox in our setup. If we enable rawlog for what log patterns should we search? Your Inputs are highly appreciated! Thanks and Regards plataleas *----- haproxy configuration ------ *frontend frontend_mail.company.org-143 bind 10.100.189.34:143 mode tcp default_backend backend_mail.company.org-143 backend backend_mail.company.org-143 mode tcp balance source server dovecot-proxy01.company.org dovecot-proxy01.company.org:10143 check send-proxy-v2 server dovecot-proxy02.company.org dovecot-proxy02.company.org:10143 check send-proxy-v2 backup *----- config Dovecot Proxy -----* /root@dovecot-proxy01:~# dovecot -n #

Dovecot migration via dsync : mail_location problem (INBOX) ?

See http://wiki2.dovecot.org/Plugins/MailCrypt + stats: Global stats can be sent to Carbon server by setting stats_carbon_server=ip:port + imap/pop3 proxy: If passdb returns proxy_not_trusted, don't send ID/XCLIENT + Added generic hash modifier for %variables: %{<hash algorithm>;rounds=<n>,truncate=<bits>,salt=s>:field} Hash algorithm is any of the supported ones, e.g. md5, sha1, sha256. Also "pkcs5" is supported using SHA256. For example: %{sha256:user} or %{md5;truncate=32:user}. + Added support for SHA3-256 and SHA3-512 hashes. + config: Support DNS wildcards in local_name, e.g. local_name *.example.com { .. } matches anything.example.com, but not multiple.anything.example.com. + config: Support multiple names in local_name, e.g. local_name "1.example.com 2.example.com" { .. } - Fixed crash in auth process when auth-policy was configured and authentication was aborted/failed without a username set. - director: If two users had different tags but the same hash, the users may have been redirected to the wrong tag's hosts. - Index files may have been thought incorrectly lost, causing "Missing middle file seq=.." to be logged and index rebuild. This happened more easily with IMAP hibernation enabled. - Various fixes to restoring state correctly in un-hibernation. - dovecot.index files were commonly 4 bytes per email too large. This is because 3 bytes per email were being wasted that could have been used for IMAP keywords. - Various fixes to handle dovecot.list.index corruption better. - lib-fts: Fixed assert-crash in address tokenizer with specific input. - Fixed assert-crash in HTML to text parsing with specific input (e.g. for FTS indexing or snippet generation) - doveadm sync -1: Fixed handling mailbox GUID conflicts. - sdbox, mdbox: Perform full index rebuild if corruption is detected inside lib-index, which runs index fsck. - quota: Don't skip quota checks when moving mails between different quota roots. - search: Multiple sequence sets or UID sets in search parameters weren't handled correctly. They were incorrectly merged together.
