SORBS?!

That is again, not true.

Senderbase's listings don't correlate to any public information so it's pretty much impossible to pro-actively protect ourselves from having our IPs set to poor.

I.e. when Senderbase assigns IPs to poor, those same IPs aren't listed on any RBLs or anything.

They operate in a vacuum where there is no visibility into why they do anything. Unlike organizations like Spamhaus where you know exactly why IPs are listed.

Thanks,

If it was industry-wide standard practice that just notifying a provider resulted in something being done, we'd not need things like Senderbase, which is after all basically a list of people who don't take action when notified...
