Solr/Tika patches for dovecot 2.3.21
by John Fawcett 03 Jan '24

03 Jan '24

Hi I've just made updated versions of 3 patches against the latest release 2.3.21 in case they are useful to someone or might get considered for official inclusion. John *dovecot-2.3.21-tika-http-auth.patch* Allows specification of username and password in the fts_tika setting for basic auth against tika server. For example fts_tika = https://user:password@tika_server:443/tika *dovecot-2.3.21-solr-max-size.patch * This is a simplified version of my previous patch. Sets a size limit (configuration fts_max_size) on message bodies that are to be indexed. Message bodies for messages larger than fts_max_size are not sent to solr. Defaults to zero which means no limit. For example fts_max_size = 10M *dovecot-2.3.21-solr-max-rows.patch * When dovecot sends a search to solr it uses the rows parameter. For multiple mailbox search the value used is SOLR_MAX_MULTI_ROWS , hardcoded to 100000. For single mailbox search the value is uidnext. This patch introduces an upper limit for single mailbox search using the same value as SOLR_MAX_MULTI_ROWS, while leaving the existing functionality of sending the uidnext value if it is smaller. This is just to place a more reasonable upper bound since uidnext can get much larger.

how to take mdbox extract of time interval and restore that again?
by lutz.niederer＠gmx.net 03 Jan '24

Hi! Due to a fatal hardware error we have to extract data of all existing imap accounts and all their boxes/folders etc. from an mdbox store starting with the 5th of december until today. Then we have to restore the old system and import the data back into it. Mail before 5th will come from the system backup, newer mail from that export. After that it may be possible that some/few mails may exist twice in the boxes, but that's ok. 1. What would be the command line for doveadm to extract everything starting the 5th? I find that the command line for doveadm is pretty complicated. I tried but I am not sure if I really got all mails exported. So I would like to ask if someone with much more experience can give me a command line that surely does what we want. The command will be run from a remote machine. 2. And what would be the command line to restore all the mails that we have exported back into the system? (The folder and account structure is the same.) 3. After that some of the mails may exist twice. Is that a problem, maybe because of internal IDs? 4. Are there any other things we need to be aware of when doing that? I thank you very much for your help! Cheers! -lutzn

Broken Docs

The page: https://doc.dovecot.org/configuration_manual/protocols/lmtp_server/ ... has links to the old dovecot wiki which are now broken, specifically the Postfix and Exim links at the bottom of the page. Can someone please port those pages over to the docs and fix the links? Peter

A bug and a misleading description
by David Van Edwards 01 Jan '24

01 Jan '24

!. I have just tried deleting Sent messages and when I put the search string 1:200 in only one message was deleted. And when I put in 1:500 again only one message was deleted. In both cases a green message box came up saying the operation was successful. 2. I successfully deleted 1000 messages from my Inbox using the search string 1:1000 but it was not clear to me that this would delete the 1000 most RECENT emails, not as I imagined the FIRST 1000 emails counting from the beginning. Is that the case? It certainly seems to have been the result and it’s rather upsetting. Should your documentation make it clear whether 1:1000 is counting forwards or backwards?
