That pretty much lists everything available to me... The colo is Hurricane Electric in Fremont, but that's only because a) budget and b) locality. I have a colo that I'm in right now that unfortunately isn't capable of providing "any service level". So my options are limited. The biggest problem is that this line of business really isn't a money make for us since large companies can simply undercut any price we set (or primary job is software architecture) and that we still have a need to support email for our custom clients. I understand the blocking issue of IP's, which is why I think ideas such as SORBS has merit (though I was burned when the reported my current ISP as a dynamic block after being static for year -- some time ago). Which is why I kind of started this thread. I know that I have to register my primary MX out services with several of the larger providers, SORBS (probably through HE), setup RDNS, and whatever else. It's that whatever else that I'm just making sure that I have done. I was supposed to receive the IP's today but haven't yet (as we had to resend the wonderful justification again). As for VPS services, I've haven't really had any problem with mine in terms of services. I check pretty frequently to see if my VPS is on any blacklist and it hasn't popped up at this point. Anyway, if you happen to know a cheap colo in that area, I'm willing to change already, but thus far I haven't found anything else in budget.
