Dovecot Director self ip
by Tomaž 12 Aug '16

12 Aug '16

Hello everybody! I kindly ask somebody to help me with this problem. I'm trying to configure Dovecot proxy with Director. On the same machine is KeepAlived that needs this configured to bind non local IP: sysctl net.ipv4.ip_nonlocal_bind=1 But as already mentioned in this email: http://www.dovecot.org/list/dovecot/2012-November/087033.html Dovecot Director needs sysctl net.ipv4.ip_nonlocal_bind=0 (if this is set, everything works ok, but we break keepalived) because otherwise the second server uses IP from the first server as "self". Is it possible to configure this some other way, so Dovecot Director doesn't try to bind to all IPs and because of above configuration, uses the first one that binds. This is the result from director status on server 1: root@u1:~# doveadm director ring status director ip port type last failed status 172.16.100.191 9090 self never handshaking 172.16.100.192 9090 never handshaking and server 2: root@u2:/var/log# doveadm director ring status director ip port type last failed status 172.16.100.191 9090 self never handshaking 172.16.100.192 9090 never My dovecot config: http://pastebin.com/RnmHRWhY Thank you very much!

dovecot 2.2.25 & deleting emails from \Junk special-use assigned folder
by Marc Jauvin 11 Aug '16

11 Aug '16

Since our cPanel installation upgraded Dovecot from 2.2.23 to 2.2.25, deleting emails located in the Junk folder (\Junk special-use), the emails end-up in the \Trash special-use folder instead of being purged as before. Is there something that changed or this some configuration I am missing? Thanks for any help regarding this. -- Marc Jauvin Register4less, Inc. 514-905-6500 x403

I have a ton of these errors in my logs: Aug 11 14:16:04 imap(xxxx(a)xxxxx.xxxx): Error: Corrupted index file...../dovecot.list.index: Header's corrupted flag is set Does Dovecot not automatically fix these? Or what is the correct action to take? -- Tom

Replication issue EOF or unknown flag V
by Rick Romero 09 Aug '16

09 Aug '16

Hi, I'm trying to sort out a replication error: It was working initially, but now it no longer works. Dovecot 2.2.25, Maildir format Delivering via LMTP. If I run doveadm replicator replicate rick(a)havokmon.com On the 'master' side I see : Aug 09 14:02:17 dsync-server(rick(a)havokmon.com): Error: read(172.16.1.86) failed: EOF (version not received) Aug 09 14:02:17 dsync-local(rick(a)havokmon.com): Error: read(172.16.1.86) failed: EOF (version not received) On the 'slave' side I see: Aug 09 14:02:10 doveadm(172.16.1.81,rick(a)havokmon.com): Error: doveadm client: Unknown flag: V Aug 09 14:02:17 doveadm(172.16.1.81,rick(a)havokmon.com): Error: doveadm client: Unknown flag: V This seems to just happen with my mailbox, so I've completely removed it on both sides, to no avail. My mailbox was re-created on the slave side, but nothing else has occurred (no folders or new mail). #doveadm user rick(a)havokmon.com field value uid 89 gid 89 home /home/prime/domains/havokmon.com/rick mail maildir:/home/prime/domains/havokmon.com/rick/Maildir/ host 172.16.1.81 proxy_maybe Y mail_home /home/prime/domains/havokmon.com/rick mail_location maildir:/home/prime/domains/havokmon.com/rick/Maildir/ Any thoughts?

custom mail_location detection for dovecot lda
by Alexander 'Leo' Bergolth 09 Aug '16

09 Aug '16

Hi! Is it possible to do something like "post-login scripting" to detect and set a per-user custom mail location for dovecot LDA delivery? I tried to use a wrapper-script around dovecot-lda that sets the environment variables MAIL="..." and USERDB_KEYS="MAIL" just like overriding userdb fields may be done using imap postlogin scripts, but unfortunately this doesn't seem to be honored. (Also tried with dovecot-lda -k.) Woud be very useful for slow migration from one mailbox format to another. Is there any other way to supply a custom mail_location to dovecot-lda?

Questions about how fts-solr works
by Radu Gheorghe 08 Aug '16

08 Aug '16

Hello, I'm quite a Dovecot newbie, so please be gentle :) Though I did my homework as well as I could, I still have some questions regarding the Solr plugin. Specifically: - I understand that by default, a mailbox is indexed on the first search and then deltas are indexed in subsequent searches. Are Emails indexed in batches or one by one? Looking at the code, I see a hardcoded limit of 1000, and I'm guessing if the mailbox is done and there are <1000 Emails in the buffer, it just flushes them, right? - if I set fts_autoindex=yes, does it mean that as soon as the Email is delivered by the MTA, it will be indexed in Solr? or does it have to read by the user or touched in any way? - also, with fts_autoindex=yes, are Emails indexed in batches? if yes, is there also a time limit besides the size limit? e.g. if only 100 messages were received - I have the same question about deletes: when do they happen, and are they batched? - what happens if Solr is unavailable? I know Dovecot keeps track of what indexed in dovecot.indexed files, but does it retry? if yes, what's the retry policy and can it be configured? Also, does it behave the same if Solr is actually available and throws an error? - the same question is for attachments, though I think this is general FTS - what if Tika fails to parse the attachment? Does Dovecot still index the Email metadata? As a side, I'm also wondering if I could use the Tika that comes with Solr (https://cwiki.apache.org/confluence/display/solr/Uploading+Data+with+Solr+C…) Can fts-solr handle attachments at all? I'm asking because I don't see that field in the default schema.xml - can I add arbitrary URI parameters to the Solr request? I see that one could fiddle with the path, which I assume will let one have one collection per mailbox (though I'm curious how that works with batches - I'm guessing one batch/indexing thread per mailbox?). Specifically, I'm interested in using the mailbox as a routing value - if I read the code well, Dovecot does a soft commit when it's done with the specific mailbox. For indexing at search time, I see why it makes sense. If I do "autoindex", can I disable that and let Solr autoSoftCommit every N seconds? That should improve indexing throughput and reduce load. I see that one can already do this for hard commits (I'd use autoCommit there, though a hard commit is also triggered when ramBufferSizeMB gets hit) - when querying, can I sort by an arbitrary field, such as the date? I saw I can sort by score, but I can't find anything in the code that will suggest it's supported - also when querying, can I specify which fields to return? I see that the plugin asks for Email ID, so I'm guessing it fetches things like from/to from the Email itself. I'm thinking that if I want to sort by those values I need to set docValues=true on them, to save memory. In that case, I might as well retrieve the original string from docValues, which should be a whole lot faster My plan is to do all sorts of tests, but having a better background on how it works will certainly help. Any pointers, feedback, encouragement, etc is certainly welcome - thanks in advance!
