do this and it works (tested sending to Exchange Servers and standard POP/IMAP apple)
Step 1: if you have a RegularUser object marked as Intelligent and it holds the attribute for email called EmailAdress - edit this and Remove the "masking as email" on the bottom
Step 2: Open your settings and edit the FromEmailAddress object to show as an example - "David Smith" dsmith@hotmail.com
everything including the quotes name quotes - the syntax is "Friendly Name" <email address here>
Works like a charm thanks for the others who pointed me in the right direction
txs, nina 😉
