Like I said...if it taxes their resources even one tenth of one percent,

It's not their resources, it's the resources they have stolen from other

NO. I'm making it sound like greylisting is NOT the world's answer to
stopping spam. It's NOT a miracle cure, it is NOT the last, best hope
for peace.
Sigh. You might want to read the paper Experiences with Greylisting
from the 2005 CEAS conference.

No, the problem is you haven't understood the point I was making.
Here's the summary as I understand it.
You're against greylisting because:
a)
Cellular operators know that their clients expect speedy
delivery of SMS, including those sent via SMTP.
Actually, in my experience SMTP to SMS gateways can have significant
delays unrelated to greylisting. Travel agencies like Orbitz send out
notices about flight changes and delays via SMTP-SMS

Email is not an instant messaging system, no matter how much you want
it to be one.
Cell phone companies won't take pages any other way no matter how much you
want them to.
This might be a good time to learn about outfits like clickatell.com

That's probably par.

Actually, no. Greylisting works because it delays the spam injector
long enough that the injector will get blacklisted by the time that the
greylist opens
