Suggestion for Challenge/Response anti-spam system on servers

[tkraffty]

Yup - It's hard to even imagine the systems-overhead and hardware and bandiwdth you all must have to manage due to spam... Like I said before, it's ironic (and I'm sure also a big pain in the butt for you) that some preventative measures might even cause *more* problems for you...

Someone should add up the cost that spam encurs on business (in terms of administrative and infgrastructure overhead) and we should all then send our invoices to the government Oh drats... but the government would just use our money to pay the bill anyways, so we're screwed either way ...

Have you pursued this at all recently?

I'd be interested if you would make it available, whereby resellers can turn it on for clients when request more spam protection, and willing to pay a small fee to keep clients. Thanks.
