Define ISP
I will sleep better tonight if I get this off my chest.
Yesterday I got an email from someone I dont know about something that needed my reply.
I replied.
Shortly thereafter I received a robot generated message from his ISP asking me to fill out a form to verify that my reply was not spam.
As I understand it, this is called whitelisting. At least some folk would like to think so. I call it being a pain in the ass ISP trying to get involved in things that dont concern ISPs.
I consider anything coming in that is not expected to be spam. I do not take kindly to some nutcase ISP spamming me about blocking spam.
ISPs need to do what they get paid for, Internet Service Providing. That is it. Spam blocking, phishing protection, adult material blocking, I dont need the ISP to do that. Those things are up to the user, not the ISP.
Take a look at the ISP version of the mission statement and compare it to the users mission statement. They may not be diametrically opposed but I bet they get close.
I dont trust ISPs to manage content and neither should you.
Besides, whitelisting needs to be done by the fellow receiving the email, not the guy sending it. If you allow the sender to fiddle with your whitelist, you are sure to get stuff you dont want or need. This is sort of like letting the IRS fill out your tax return. How many of you do that?
