Use second IP address for mail server
I leased a dedicated server from a large ISP a few months ago. The primary IP address apparently had spam problems historically.
At this time it seems the whole range of IP addresses for this ISP (126.96.36.199/24) seem to have a poor reputation with Cisco Ironport, and a couple of our clients hosted on this particular server are being blocked. The ISP has been deaing with Cisco for moe than a week about it, but no resolution so far.
The server has never had spam passing through, the mail flow is almost nothing. The Ironport reports on it do not show spam as far as we can see, but the reputation remains "poor".
The server has 5 IP addresses. Can one of the "clean" IP addresses be used for the mail server IP? The server runs Centos 5 set up as a "Perfect Server" running ispconfig 2, postfix, dovecot etc.
Any ideas or any way to get around that server's IP with a bad rep?
