See: https://doc.dovecot.org/settings/plugin/fts-plugin/#plugin_setting-fts-fts_tokenizers This has nothing to do with flatcurve (or any FTS driver) - Dovecot will never send the full "/home/johndoe/render.php" to the driver to be indexed. > fts_autoindex = no > fts_enforced = yes > > A search command like this: > > doveadm -D search -u j...@doe.com mailbox INBOX SUBJECT > "/home/johndoe/render.php" > > should show the messages with subject: "CRON: /home/johndoe/render.php OK" > but produces a lot of extra undesired results and I think the second line in > this debug output indicates the reason: > > May 23 07:44:13 doveadm(j...@doe.com): Debug: fts-flatcurve(INBOX): Query > (hdr_subject:/home/johndoe/render.php*) matches=0 uids= This is correct, since "/home/johndoe/render.php" was not indexed so there should be zero results. > May 23 07:44:13 doveadm(j...@doe.com): Debug: fts-flatcurve(INBOX): Query > (hdr_subject:php* AND hdr_subject:render* AND hdr_subject:johndoe* AND > hdr_subject:home*) matches=272 And this is also correct, as the search phrase is attempted by searching both its full string and also all of its tokenized components. (Both the original text and all search terms are processed through the tokenizer before passing to a FTS driver.) > I tried rebuilding the indexes with "fts_flatcurve_substring_search = yes" > too but that didn't change anything. It works as expected with lucene plugin > because in that case header search is performed via dovecot indexes instead > of FTS. May be I am not doing something right in configuring this new FTS? I'm not a lucene expert... but with the old lucene plugin, you were almost certainly using it without Dovecot tokenization support, since the plugin predates it (I think) - using Dovecot tokenization would have required 'use_libfts' to be present in the fts_lucene setting (which I doubt was ever documented). I believe Dovecot was just doing simple white-space tokenization instead, so lucene code/library was likely receiving the full string and doing internal tokenization. michael ___ dovecot mailing list -- dovecot@dovecot.org To unsubscribe send an email to dovecot-le...@dovecot.org

I can try looking around the core file next week to see if it gives any good insight. Aki ___ dovecot mailing list -- dovecot@dovecot.org To unsubscribe send an email to dovecot-le...@dovecot.org

Which version of Dovecot are you running? The /3.0/ documentation is for unreleased version of Dovecot. Also, since you are already authenticating the user on the submission service, why not use submission xclient to pass the user etc. information to the backend MTA instead of re-authenticating the user?

subscriptions via master user
Hello,
When I impersonate an regular user using master user (log in to
Roundcube as "user*masteruser") - there are user's subscriptions
missing. I can see all folders, but have to manually enable visibility
in settings.
Is this normal? Can I fix it?
passdb {
driver = passwd-file
master = yes
args = /filepath
pass = yes
}
passdb {
driver = passwd-file
args = /filepath
}
userdb {
driver = passwd-file
args = /filepath
default_fields = uid=vmail gid=vmail system_groups_user=vmail
home=/srv/vmail/%d/%n master_user=%u
}
