Hello.

I have email server with two public IPs and I want to send all forwarded mails via specific IP to prevent primary IP to become blacklisted.

So:
primary public IP: send all emails that are actually send by email user, hosting on email server
secondary public IP: send all email which have been setup to be forwarded in SOGo sieve or iredadmin

How can i achieve that?
