I recently had a spamming incident and got listed on a blacklist. I have rectified the issue, removed from the blacklist, but my IP reputation is now classified as a high volume sender.

What is the best way to rectify this? I have an additional IP address. I am thinking configure my server to make outbound SMTP connections using the other IP.

My questions are:

How long does it take for my reputation to stabilize again?
How do I configure my server/mailserver to use a specified outbound IP?

Setup:

Server 2008 Web
hMailserver
2 IPs configured on one NIC
Cloud based server

Your urgent help would be greatly appreciated.

Cheers
