Exchange Edge Transport AND Exchange Hosted Filtering

Hello,

Is it at all possible to use Edge Transport in combination with Exchange
Hosted Filtering?

The requirement is "USE a gateway in the perimeter" and Use Exchange Hosted
Services if possible (or find another service provider) for all out going
and incoming mail by:

Have a secondary MX (that has a priority much higher than frontbridge) point
to the edge transport server as backup (yes forefront will be protecting
that server, could be changed to primary MX record when hosted services is
down or not wanted anymore).

Send all outgoing mail to Frontbridge, (to be changed in case the hosted
services is down or not wanted anymore).

Can it be done, I know it goes against the docs that say that edge transport
should not be used with Exchange Hosted Services but this is a requirement.
I think it can work but I would like your input on this (how and what) .

Thx

It would be pointless because Edge wouldn't pick anything up.

Don't go creating multiple MX records. The Frontbridge service isn't
one box, it's an armarda of kit all over the place. That's about as
likely to go down as Message Labs (famous last words)

What do you want; protection or just another box in a perimiter?

I want a good solid solution :-) And I agree with the short but correct
assesment. But life is not allways that easy.

Any way policy says the mail needs to be delivered to perimeter.  So it
might as well be a linux box doing nothing but relaying mail :-) in the
Frontbridge scenario.Customer wants a box in perimeter (policy). There is a
big distrust in hosted services and MS is not making things easy on the
Forefront / Hosted Services level with their licensing scemes, pricing and
software assurance which doesn't seem to be a good fit for them. It might
have nothing to do with technical issues but it does make them weary of the
services rendered.

My stance is either go for hosted solution or do it yourself, don't mix. Not
both. But that box in the perimeter is a requirement. Perhaps it will be
dropped in due time but today we discusses issues about the pricing and
possibilities and the price per user per year that they get from their
current vendors for Anti Spam and Anti virus (Mcafee for all PC's, servers,
mail, gateway) priced at 68% of the MS offering for Frontfront anti virus
(Mail only) and Anti-spam (hosted or not). This combined with the MS
sales/licensing - they should really make it easier to be a customer in both
sales schemes and easy of optimizing for real client needs- and the "taboe"
word Software Assurance wiped the entire Exhange Hosted services / Edge
Transport idea of the table today for complete review :-)  We're back to
what they have: a mail gateway in perimeter. The "service" business has in
many ways promised so much that never materialized for their organization so
this which leads to only one conclusion I think: it's not for them. And
tryong to do both is a little madness.

Thx for your time.

MS are pushing Hosted in a big way so if the take up isn't high you
can bet your boots it'll come down. Compare their prices to Message
Labs, how competetive are they? I haven't actually looked, not being
concerned with such vulgarities as cash and all.

I like the DIY path, in which case Edge would be deployed as the
licensing would be competetive with FrontBridge/Message Labs etc.
There is the 3rd option of an appliance that you can stick into the
DMZ and then have it deliver mail to a CAS/HT on which you deploy the
anti spam (it's a monad script in the scripts directory) agents. That
way you have a non MS appliance which pleases certain quarters in the
business and you also have a 2nd line of defence on a box that isn't
your MB.

When in such a state, maitain it! :-) Comparing vulgarities has been
increasingly difficult due to sales tactics. I bet they are competitively
priced, that's not the main issue, the main issue is the price difference
with the DIY solution (combined with a "healty" distrust for people who want
to be your service "partner" for a price (sounds like another profession , I
don't know ...).

The main beef they have, and when looking at the numbers is I have to
concur, is all pricing is based on bundling of modules/suites/funcionality
which makes a decent price for one function hard to get and wich leads to
issues when you don't throw out everything you have for something else. The
price impact that would have on roll outs, changes etc ... is easily
forgotten ... My advice to anyone trying to break into managed services is
make your licensing/pricing so easy, transparant and competitive that one
should be a fool not to use it instead of the entire hard mess that world
seems to be today that comparing is almost a "mission". You might laugh or
cry at it but I've known companies to buy stuff just te be done with the
entire hassle of trying to get the better deal. Sort of like taking the blue
pill or the red pill ...

When you have some good staff, some money, well you can get a lot of stuff
done at a price any service vendor is yet to break. If you don't have any
staff or bad ones well yes ... takes their wages and throw them in to the
equation. How ever the price of a small good IT staf that runs most of the
stuff versus hosting it all ... well that I'm not convinced about. Or is the
quality and supply of good It staff that low?

I do appreciate you opinions. Thx for sharing.

I have been quite surprised about IT staff since I started a new job.
Most I have met are very keen but I have been disturbed that we're
getting business from companies who employ staff that I would expect
to know the stuff. I guess it's just a case of the staff requirements
exceeding the ability of the market to supply appropriately skilled
staff. It'll balance out in the end.
