Ok, I've been doing my homework on setting up a second Internet domain for our Exchange 5.5 SP4 server. It didn't work exactly as I was expecting, but I believe things are working correctly. All I did was add the second domain to the routing tab in the IMC and routed it to our original domain. Now I can use username@either_domain <mailto:username@either_domain> and it works great.
Now, from what I have read, no SMTP addresses will automatically get generated for the users, they still just have the original address. This is the part I wasn't expecting. I was thinking that I could go to the Site Addressing section and add a second SMTP address. However, that doesn't appear to be possible. So, my first question is, say I wanted to change everyone's main address to the new domain. Would I make the new domain route to "inbound" and have the old domain route to the new one and then modify the Site Addressing section so that the SMTP address is now @new_domain? This is just hypothetical and probably won't ever happen, but I'm trying to learn some new stuff. I'm assuming that if you update the SMTP address under Site Addressing it will then update all the mailboxes, please let me know if this assumption is incorrect. Finally, my last question, which isn't really related to two domains. If I wanted our employees to have email addresses like [EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> AND [EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> , how would I go about it? I was thinking I could set it up in the Site Addressing section for one of the naming schemes, but how would I add a second one? Our parent company does this but they are running Notes/Domino, not Exchange. Thanks for the help, Allen List Charter and FAQ at: http://www.sunbelt-software.com/exchange_list_charter.htm
