Sieve: carry global variables from sieve_before to user sieve scripts
by Alexander 'Leo' Bergolth 26 Oct '14

26 Oct '14

Hi! Is there a way to initialize global variables with default values in sieve_before scripts that can be used in the sieve_default script or in user scripts? I've tried the following code but this doesn't work.. before.d/10-set-defaults.sieve: -------------------- 8< -------------------- require ["variables", "include"]; require "vnd.dovecot.debug"; set "global.S_TESTVAR leo"; debug_log "LEO SIEVE: in before.d/10-set-defaults, S_TESTVAR: ${global.S_TESTVAR}"; -------------------- 8< -------------------- default.sieve: -------------------- 8< -------------------- require ["variables", "include"]; require "vnd.dovecot.debug"; global "S_TESTVAR"; debug_log "LEO SIEVE: in default.sieve: S_TESTVAR: ${global.S_TESTVAR}, ${S_TESTVAR}"; -------------------- 8< -------------------- Is there any other way to set up defaults in a global sieve script?

imap-postlogin and doveadm
by Hans Morten Kind 26 Oct '14

26 Oct '14

We are configuring location= running a bash-script during imap-postlogin setting $MAIL in $USERDB_KEYS, as described in wiki/PostLoginScripting.txt This works fine. However, running a command like 'dovadm index [-u user] folder' only works for users with settings that match the default in mail_location= Would it be possible to make the location available for doveadm in a similar way, either with command line arguments or in the enviroment? hmk
