Spam related stupidity
I used to use Verizon DSL. The main reason I switched from Verizon DSL to Cox High Speed Internet is because Verizon required all mail sent through their SMTP servers to have my “@verizon.com” address in the “From” field. They said this was to fight spam. You and I both know that this was either a) evidence of Verizon’s gross incompetence, b) a deliberate lie, or c) both, because requiring “@verizon.com” in the “From” field has nothing whatsoever to do with spam. So now I use Cox High Speed Internet, and I’ve been very pleased with them.
Let’s assume that Verizon wasn’t lying to me, and that someone there really thought that their policy would have some effect on spam. Sure, it’s hard to believe anyone could be so grievously stupid, but apparently such spam-related stupidity is pretty common. For example, there are a number of ISPs which block port 25. This is pretty damned stupid. I’ll let George Ou tell you why.
