Bulk email will always raise heckles. It's not something I'm involved in
- quite the contrary - I work in *blocking* it.

But as you rightly point out, bulk email in itself is not spam. Facebook
send bulk, eBay send bulk, Amazon send bulk etc. Whilst it can be argued
that some of this is irritating and spam like, permission based bulk
emailing is a fact of life. In fact this very mailing list is bulk by
nature.

With that in mind, and the fact that email is still an effective
communication medium (just as the Post Office how much of their business
it has eaten) it follows that some people who work with MTA's may, at
some point, be asked to look at providing solutions for legal bulk
emailing. It's not witchcraft or black science - just a legitimate fact
of life (even if some of us find it quite depressing).

As our economy struggles to find its feet, communication, advertising
and marketing are going to play their part, and email is going to play a
part in that - like it or lump it.

FOOS and Bulk Email are nothing new. There are great projects out there
(http://www.openemm.org/). My question was just a hypothetical based on
some outlandish claims of an MTA provider who happens to charge a little
shy of $4k a year in licensing. I had hoped it to be a valid and
interesting question that got a good cross-sectional technical response.
On this occasion it was shot down and the best technical replies came
from the Postfix list, where there was (unusually) no abuse or fighting,
just a great response. Something that used to happen here :-(

I've been posting here for a couple of years and I don't profess to have
the experience or skill of many here. I'm physically disabled with
failing sight and dyslexic too boot, making things a bit of a challenge
some times. To be able to ask skilled experts for views and help is a
lifeline to me, and I apologise if I ruffled any feathers doing it. I
wish I never asked now!
