This has been remedied in 2.3. Unfortunately there is no clean fix to this, they all resort to various levels of trickery. Variables set in passdb/userdb overwrite the ones in plugin {} section.

Dovecot 2.3.0 TLS

All, our dovecot installation provides a bundle of intermedia CA certificates using the ssl_ca option. 2.3.0 does not supply the bundle, resulting in various clients either complaining about an unverifiable server cert, or quietly not connecting.

Repository / builds for Debian "buster"?

Hello, I am using the ‘auto = subscribe’ feature in the mailbox configuration section in the usual fashion (as shown in conf.d/15-mailboxes.conf): namespace inbox { inbox = yes mailbox Drafts { special_use = \Drafts auto = subscribe } ... } When I connect to an account with the Thunderbird mail client, those mailboxes/folders get autocreated and autosubscribed. Good! INBOX, however, does not get subscribed to automatically. When I look at the account’s subscriptions in … [View More]

FreeBSD 11.2 Postfix 3.3.2 Dovecot 2.3.4 I am trying to use dovecot lmtp with postfix to verify authentication of incoming email and to avoid being a spam relay (an issue I was having using sendmail as my MTA).

FTS delays
by Joan Moreau 21 Apr '19

21 Apr '19

Hi When I do a FTS search (using Xapian plugin) in the BODY part, the plugins returns the matching IDs within few milliseconds (as seen in the log). However, roundcube (connected on dovecot) takes ages to show (headers only vie IMAP) the few results (I tested with a matching requests of 9 emails) What could be the root cause ? Thank you
