Hi, I would like to implement Open Dkim on my server but I don't want to broke postfix.. Actually there is some filter like RBL, SPF.. And second thinks, I would like to prevent my server to be a source of spam; for this.. I've an idea but don't know if it's possible and how to do it.. So, it should be a cron, this One check the queue (postfix) and if queue > X then I disable the account.. But how to do that? Thanks !!!
