I want to configure Exchange 2003 to accept email for two internet domains. I know how to do this by adding another domain to the default recipient policy. I also want the users to be able to send email from either domain by changing the address in the "from" field.
I have set this up before by creating an additional user for each account and changing the default email address for the dummy user and then setting "Send as" and "Send on behalf of" permissions.
I have lost my notes and cannot find the knowledgebase article at microsoft.com - I think that it has been taken off.
Can someone point me in the right direction on either where to find the article that I refer to or maybe suggest a better solution if one is now available (It was a while ago I configured this before)
I don't want o use a third-party tool like ivasoft choosefrom.
To sum up I need to configure exchange for a user to send email from firstname.lastname@example.org or email@example.com by using the from field.
