Customer wants to customise the Directory Connector to create a different smtp domain name for the emailaddress field for each mail contact created for domino users. This is the emailaddress field in the General tab for the Mail Contact (not proxy or target address).
For example, currently all AD Mail Contacts have the emailaddress populated as name@DomainA.com (matches the internet address in Domino). Customer wants to change this to name@DomainB.com . The left hand part of the address needs to stay the same as the left hand part of the Domino internet address.
