You said something about black lists, if you mean mail blacklists then a dedicated i.p. wouldn't help either since they black list the host names ip not the websites ip.

I have to correct myself.....iptables doesn't work with virtual interfaces
so what I was thinking doesn't work......my bad
I'll think of another
reason then.......I'll get back on this
About the blacklist I never said anything about single ips or ips of websites
being blacklisted. I said it can't hurt to check the dbs of organisations that
maintain blacklists such spamcop/spamhaus in case the previous "owner" of
your ip addresses got your ips blacklisted. Quite often they block a whole
range instead of single ips. If you see any ip within your range is blacklisted
you should contact them and request removal.
Not every blacklist works by FQDN or hostnames many spamlists blacklist
by ip of the MTA caught spamming or as mentioned before a whole range of
ips from the provider that hosts the abusive host.
