Restrict Hub Transport choice in Exchange 2007?

Hello. If you have 2 mailbox servers and 2 hub transports, is there a
way to have each mailbox server only use one of them? The two hub
transports can communicate between themselves normally so messages
will still flow.

If you have two AD sites, you can have a HT and MB server in each, but
is there any way to do it when they are in the same site?

Thanks,

Neil

First question is really why would you want to do this?

If one Hub goes down then one Mailbox Server cannot send mail. You are
removing built in HA.

I can't see any benefit to what you want to do at all.

There is a way to do it, i'd have to check my notes however..

Thanks for the update. As for why, a customer has a security
requirement where certain classes of user get specific server
hardware / builds. So they want 'User A' to have a dedicated set of
server hardware and software, and 'User B' another.

It's a fairly peculiar set of requirements :)

Have you told them they're mad? :-)

Maybe not quite as bluntly as that... <cough>

All I can do is list out the specifics of the insanity in business
friendly language. If they still want to go ahead, I tip my cap, go
ahead with what the customer wants and smile on the way to the bank :)

And there's a certain perverse part of me that is curious about doing
a different implementation.

Use the SubmissionServerOverrideList paramter.

It actually can be a useful switch. I know people who do this so that
a certain mailbox server only communicate with a certain HT that then
routes messages to a specfic server etc...

Thanks for the information. The main downside is the extra servers
required to provide fault tolerance (4 HTs required instead of 2 for 2
MB servers, for example) and the extra complexity for the routing from
a support perspective. But they're happy with that.

Thanks again,

Neil

Fair enough I guess, take care,
