In addition to what Al said, DSaccess and DSProxy are the 2 components
responsible for locating, resolving and providing referrals for internal users located
AD. SMTP Categorizer uses DSAccess to resolve a mailbox addy to a user (and for
other things). Exchange knows to send an email to an external server by looking
at the domain name part of the email address and determining whether it is
responsible for THAT domain or not. If it is not responsible for the domain,
Exchange (nay, all SMTP servers) categorizes the email as outbound. If it
determines that it is responsible for the domain, it then utilizes its
components to resolve the mailbox and route the email for delivery based on the
resolution. It’s more involved than that, but you get the gist. When you get to the Exchange Library site, be sure to look for the “Exchange
Technical Reference” doc. Deji -----Original Message----- Exchange doesn't care about internal/external in that way.
Exchange is SMTP based and follows the concept of authoritative for a domain or
not. That's configured via Recipient Policies GUI typically. GUIDS to find users? I've never heard that and can't comment past
saying that a user-object has a guid and an SMTP address as attributes. They
are connected and could be used, but why? Homemdb (and several other
attributes that must exist in order to qualify for mail receipt) would be more
useful I would guess. As for addresses, Exchange has to do lookups for the SMTP addresses and
then deliver the message. Since it's SMTP based and uses a centralized
directory service, as mail comes in from external systems (external to Exchange)
it MUST lookup the address either in cache or in the directory itself to
be able to bring the transaction to resolution. That's where the 1:4
MHZ server to GC recommendation comes from; you'll knock over a GC in a high-volume environment if you're not careful. As for docs that explain internal routing, you can find those at http://www.microsoft.com/exchange/library and I would suggest the troubleshooting routing docs. Does that help?

with a smtp address? or rather, how exactly does exchange tell if an address is in AD or out
on the internet and how does it find the owner of said address(if in AD)
under the hood? are there any docs you could point me to? thanks joe wrote: > Yep.
