Fatal: write(indexer) failed: Resource temporarily unavailable
by Joan Moreau 06 Nov '20

06 Nov '20

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.
