Also, when opening up a ticket based on a forum thread, it is great if the forum thread can be referenced in the ticket. I just got the new ticket (1562010) and had to find this forum thread accidentally while reading the forums at the same time.
// Minimal value of user's 'keep_alive' setting (in seconds)
// Must be less than 'session_lifetime'
$rcmail_config['min_keep_alive'] = 60;
