<div>Do you have a permanent static IP address? If not, you

<div>Also, it seems to me that even permanent static IP
addresses are not made the same. I get a feeling that some
spam databases do not "like" certain ranges of IP addresses.
Although I have no direct evidence of it, I suspect that
these spam database sites run periodic checks on how much
spam a subnet produces and when it exceeds some threshold
the entire subnet is marked "dirty".</div>
