Hello I have this issue for Xapian plugin: https://github.com/grosjo/fts-xapian/issues/62 But I am not sure where can it comes from. Is dovecot calling some specific function in the plugin after the init, that would create such error ? In doveadm dealing differently with plugins that dovecot core does ? Has there been some recent changes in the plugin framework that would lead to such error ? Thank you

Understanding the limitations of Dovecot Submission Service
by R. Diez 04 Nov '20

04 Nov '20

Hi all: The Dovecot Submission Service is very enticing for laz... I mean for busy people like me. A couple of lines in dovecot.conf , and you have a local SMTP server that does authentication. No SASL loops to jump through! Very cool people like me also appreciate cool new features like BURL. But now I want to understand its limitations. Say I just bought e-mail domain xxx(a)example.org . Say employee A has e-mail address a(a)example.org . It this employee turns evil, will he/she be able to send e-mails impersonating b(a)example.org ? Or does the Dovecot Submission Service check that he only has permission to send as a(a)example.org ? My requirements are pretty modest. Basically e-mail should just be sent all right. But are there any other reasons why I should avoid the Dovecot Submission Server anyway? The documentation does not really say much. Thanks in advance, rdiez

Panic-Error (ctx->nested_parts_count > 0)
by Andreas Piper 04 Nov '20

04 Nov '20

Hello, on my dovecot-replicator-backend I see lots of panic-messages "assertion failed: (ctx->nested_parts_count > 0)", produced from a single user. I assume that this is correlated with https://github.com/dovecot/core/commit/a668d767a710ca18ab6e7177d8e8be22a6b0… How can I identify the incorrect formatted message in the user's mailbox? I want to remove it, as the error-processes drive up the backend's load incredibly. Will a fixed dovecot-package be out soon? Any help is appreciated.

Feature Request: Redis support for username and TLS
by Mark Moseley 04 Nov '20

04 Nov '20

I was wondering if there was any imminent support in 2.3.12+ for using a username to log into Redis, as well as support for using TLS to connect to Redis. And if not, I'd like to put in a feature request for those two things (AUTH with username/password, and TLS connections to Redis). Specifically, I was looking at using a username/password combo to log into Redis for the quota_clone plugin. I found the 'password' param in the source (not documented at https://wiki.dovecot.org/Dictionary) There's no 'username' param (the 'username' in the source seems to refer to the mailbox, for the purpose of building the key name). Redis 6 supports authenticating with a username and password, as well as the ability to listen on a TLS-enabled port. Both of these significantly improve security, combined with the new ACL system. Obviously, these Redis 6 features are brand new, so I'd be shocked if they were already supported. But it'd be awesome if those were added to Dovecot :) Currently, I've got a localhost Envoy proxy doing TCP proxying from localhost+non-TLS to my Redis TLS port, which is a kludge at best. There's a neat Envoy Redis proxy that *almost* does the trick but the Envoy Redis proxy unfortunately doesn't support MULTI/EXEC, which Dovecot quota_clone uses, or I'd be using that instead of a plain TCP proxy (since the Envoy Redis proxy can use a username/password+tls to connect to the upstream Redis).
