Any clues what could be the cause of such problem?
Ok, I was wrong. In 2.4 vnd.dovecot.environment does not work at all. It
looks like a bug. Could some dev look into it, please? Sieve script to
reproduce problem printed below. You can reproduce it on build-in
varialbes. No need to set custom config variables. So should be easy.
I loaded: environment variables vnd.dovecot.debug vnd.dovecot.environment.
- environment variables vnd.dovecot.debug - works, I can access
environment "version" variable, I can debug log, I can set variables.
- vnd.dovecot.environment - does not work for some reason, I can not
access build-in nor config variables
Sometimes on logs I see such error, but it shows up randomly:
- dovecot0: lmtp(test.u...@domain.com)<66724><ZAM4IH6TNWikBAEAXAnA5A>:
Error: sieve: 0000.test: line X: referring to variable in unknown
namespace 'vnd'
More logs and sieve trace below.
Dovecot config:
sieve_extensions = environment variables vnd.dovecot.debug
vnd.dovecot.environment
Sieve script:
require "environment";
require "variables";
require "vnd.dovecot.debug";
require "vnd.dovecot.environment";
if environment :matches "version" "*" { set "environment_version" "${0}"; }
if string :matches "${vnd.dovecot.username}" "*" { set
"dovecot_username" "${0}"; }
if string :matches "${env.vnd.dovecot.config.fs_group}" "*" { set
"dovecot_config_fs_group" "${0}"; }
debug_log "environment_version= '${environment_version}'";
debug_log "dovecot_username= '${dovecot_username}'";
debug_log "dovecot_config_fs_group= '${dovecot_config_fs_group}'";
debug_log "vnd.dovecot.username= '${vnd.dovecot.username}'";
debug_log "env.vnd.dovecot.config.fs_group=
