I have two different internal domains , where i need to send mail from one domain to another domain using Common Name. conditions: It is from Web, Not from Notes Client. Reason why I'm using common name is We configured and used the common names for all the employees which we don't want to change For this Can we do anything on server configuration? I can see different setting in admin client but sure where or what will fix From Admin Client-server- Configuration setting -Router/SMTP - Address lookup : Fullname Only Above will do anything for my issue?
