Comment terrible ISPs (Score 1) 252
Earthlink and Comcast customers account for a significant amount of SPAM sent to my email server. I have contacted these ISP's repeatedly with date, time, and IP address of the offenders with zero response and I continued to be spammed by these same IP addresses.
I have Earthlink and Comcast designated as "terrible ISP" internally and now firewall out IP addresses sending spam from any ISP so designated.
When people are sending these ISPs all the information required to stop spam and they do nothing, I think anything they have to say regarding stopping SPAM rings hollow.
We are not talking best practices here, they cannot or will not do the minimum.
