Hi,
Issue: Sieve works perfectly and does deliver the mail to the correct mail directories. However Thunderbird doesn't detect the new email, until the user clicks on the folder and then all of a sudden it shows the newly detected emails. Perhaps this is a task for the Thunderbird forums? (Thunderbird 24.2.0) Server Side: * CentOS release 6.3 (Final) * dovecot-2.0.9-7.el6.x86_64 * dovecot-pigeonhole-2.0.9-7.el6.x86_64 * postfix-2.6.6-2.2.el6_1.x86_64 * Server Sieve Settings: mail_location = maildir:~/Maildir plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_vacation_default_period = 10d sieve_vacation_max_period = 30d sieve_vacation_min_period = 1h } * Client App: - Thunderbird 24.2.0 * Userlevel config; File: ~/.dovecot.sieve require "fileinto"; if address :is "to" "sysad...@example.com" { fileinto "sysadmin"; } elsif address :is "to" "root@" { fileinto "sysadmin"; } elsif address :is "from" "root@" { fileinto "sysadmin"; } cya Craig
