Wanted to know if now AntiSpam and Mail Policy programs installed by iRedMail is updated and working fine on Ubuntu 15.x version ?
Also if I have multiple domains on a single IP, because not all domains would have reverse DNS, what does iRedMail oconfigure to avoid the email from being marked as spam or undelivered by Gmail?
