Hello again. I'm quite new to SMTP setups, and we want to send email invites to a lot of persons and if we are sending more than 100's at a time, we are afraid of blacklisting. So I google and one of the soluions is IP Rotation, how would we do that in iRedMail? I tried googling but there isn't too much stuff available, or it doesn't make sense to me. I have 5 public ip's available for rotation. Currently I already set it up on my interfaces config. What's next after it?
