RE: Not even sure how to title this..
Jeff... I am intimately familiar with this issue and most of its mutations. I am an Exchange / AD consultant and just completed a migration to E2K of 22,000 mailboxes where 3 mail systems all shared the same SMTP domain name. It took a little work, but routing is efficient and works like a charm. It all depends on the exact details of your implementation, but in a nutshell: you have to close the loop somewhere, and I suggest you let outside mail come in to the E2K boxes (like you already are). These servers will deliver the messages if the recipients are on E2K or the 5.5 boxes (they're in the same Org. right? So they'll know of ANY Exchange recipient, not just the ones residing on the E2K boxes, and they'll forward to the 5.5 boxes directly or based on routing group connectors, or whatever you have joining your sites) and if they don't see the recipient as having a mailbox on any of the Exchange servers, they'll pass it on to the Sendmail box. The Sendmail box then needs to either deliver locally, or NDR. The logic being, if Exchange passed it on to it, the only other place the recipient can exist is on the Sendmail box itself. So if Sendmail doesn't host the recipient, then it is safe to NDR the message, and it shouldn't send it to any of the 5.5 boxes. To make all of this work, the other key is to have the E2K boxes, which receive the outside mail, know of everyone on the inside of your organization - whether they're on Exchange or not. This way, the E2K boxes will accept mail for anyone on your internal mail systems (listserv lists, etc.) There are a bunch of different options on how to get Exchange to forward the messages to your smtp.domain.edu server, but I've found the forward unresolved... not to be the best choice... There's lots of little nuances in these scenarios, but it is possible, and actually not all that hard (once you've beat your head against the wall for a few weeks and found out a handful of undocumented things). I feel your pain on this, and would be happy to have a quick chat with you if you like. Send me an email at [EMAIL PROTECTED] and we can arrange for phone call.

Additionally all mailboxes in Exchange have an additional e-mail address of [EMAIL PROTECTED] (besides their primary of [EMAIL PROTECTED]).. this is so mail routed through smtp.domain.edu can route the smtp mail to either a sendmail box or exchange for example if [EMAIL PROTECTED] comes in to smtp.domain.edu and he is on exchange, the address is re-written to [EMAIL PROTECTED] ... if he is on the Sendmail box the address is left unchanged. --In E5.5 we have CRs configured with a primary address of @domain.edu and a forwarding address of @domain.edu (before my time and I'm unsure as to why it's this way)... messages addressed to these CRs flow out the IMC on e55-mail01 Problem: If I address a message to [EMAIL PROTECTED] this will route through smtp.domain.edu (sendmail) and into e2k-mail1 or e2k-mail2 (E2K)... these servers will not find this address... they will then (because they are configured to) route this to smtp.domain.edu (passing it through e55-mail01 on the way to smtp.domain.edu).. this is a mail loop and fills the transaction log drive on e55-mail01 summary: 1. email to: [EMAIL PROTECTED] (not a valid address in exchange) 2. smtp.domain.edu (sendmail) receives it from the internet 3. e2k-mail1 (or e2k-mail2) receives it from smtp.domain.edu 4.

Mail from exchange - if addr matches a primary address for a custom recipient that is forwarding to @domain.edu that is not resolvable locally, send it to smtp.domain.edu, do not treat it as a bounce.
