Elliquiy has had no issues with spammer lists since leaving Ubiquity.
Even while at Ubiquity, our issues were limited solely to Outblaze and, at the tail end of that clusterfuck, Ubiquity got an entire /18 dropped into the SBL with us in it.
It was never targeted at Elliquiy at any point. I actually talked to the Outblaze people personally.
There were issues that caused trouble with specific ESPs. Most recently an error on Microsoft's part, and before that Google was having issues with our IPv6 allocation.
Nothing regarding us is going to have anything to do with you, however. How would we send stuff from your IP? Why would we do that if we could?
