David, once again many thanks. This sounds logical and I appreciate your help. I am now reading the articles you refer to.
I had posted the "multiple smtp routing question" which you kindly answered earlier because of the need to route messages between these organisations and at the time thought the interorg tool would not work in my set up. Based on your answer here (i.e. replicating routing information via the interorg tool) I would assume that the inter-org agreement would handle the routing of messages correctly and I would not need to maually set up multiple smtp connectors to the e5.5 org addresses? This is why I was asking that earlier question. Now all I am left with is the routing email to and from the internet for migrated users from the E5.5 orgs that now reside on the E2k server. I would assume I should do this by setting up the standard Virtual SMTP server on the new E2k server to route all outbound emails to the smart host on the internet. Where would the E2k server send the email for a migrated user on E2k if he wanted to send email to the internet. Would it go though to his old server and out through the internet and how would it get back to him etc etc Or would it work like this: --------------------------- As the E2k org is essentially one org with the E5.5 org, the E2k org knows what is internal (i.e. the replicated routing information) and anything else would be sent externally via it's own smtp virtual server. Any incoming internet based email would still come in throuh the E5.5 internet mail service until it was switched ioff and the mx records were repointed to the e2k server? Am I right?
