How Pervasive is ISP Outbound Email Filtering?

Erris writes "A member of the Baton Rouge LUG noticed that Cox checks the text of outgoing email and rejects mail containing key phrases. I was aware of forced inbox filtering that has caused problems and been abused by other ISPs in China and in the US. I've also read about forced use of ISP SMTP and outbound throttling, but did not know they outbound filtered as well. How prevalent and justified is this practice? Wouldn't it be better to cut off people with infected computers than to censor the internet?"

I'd say that every ISP should do that, that is, if you could get it unblocked if you requested it or via some online account management.
99% of all people wouldn't need it anyway(except the bots on their machines) and the ones who do, would know how to open it. Of course it is a not the ideal way to solve the problem, but it's all we got for now.

You forgot about the US government

However, filtering also raises the "you are now liable for what they say to an extent" issue that the whole Safe Harbor thing was suppose to fix for ISPs and could definately cost a huge pile more than just cutting access and losing customers. People have raised that idea as wel about AT&Ts plan to filter their network for copyrighted material.

The answer I have to that is "9/11 Changed Everything".

Seriously -- when the US government asked the telcos to commit surveillance crimes against the US citizens, only Qwest refused. Usually, breaking the law is a bad thing, but the US government was offering lots of money to the telcos, and presumably the promise not to prosecute. So the only company that got in trouble was the one following the law. And somehow the Qwest CEO that refused the deal ended up in jail. Meanwhile Dick Cheney is desperately trying to get immunity for the cooperating telcos for their crimes. See how that works?

So on the surface of things scanning and filtering our email might seem to be a bad busines move. But if the same US Government that got illegal telephone surveillance of US Citizens is also going for illegal surveillance of our emails, email filtering starts to make much more business sense.

It used to be that the idea of the US government secretly finding out what was in your emails was in the tin-foil hat realm. But the illegal surveillance of telephone calls would have been as well, along with secretly torturing people in secret overseas prisons. As well as "constitution-free" zones such as Gitmo that are paid for by US taxpayer dollars.

So if you have a government that scans your telephone calls, email, and web-surfing habits, you get very close to a goal of "total information awareness", which was one of the government's programs that was renamed and shuffled around after the public got very upset.
