Notes Mail not to display delegated address when mails were sent by the delegated users Merged

When mails were sent by delegated users, they are displayed as sender on their recipients mail docs.

But when they don't have internet addresses, they can't receive return mails from outside if recipients reply to them(not mail file owners)

Request new function or setting to delete the delegated user info from the mails and only the mail file owner's address is displayed on the recipient's mails when mails are sent by delegated users.

If we set "from" at [Notes items to be removed from headers:] of Server configuration settings ([MIME]-[Advanced]-[Advanced Outbound Message Option]), it would be implemented for outbound mails. but the change affect all outbound message. And that's high impact and negative impact on delegated users who have internet addresses.

Need the new function to set per mail databases or per senders.
