As far as I know only address can be dynamic using expressions. Names are static

@james.franklin Hi, to the best of my knowledge and as per my experiences with Email configurations and as per the documentation, it isn't possible .

Until and unless we miss something where Appian folks or Practitioners who are experienced in Mail Server Configurations can let us know, it's evident from the Document or Configuration files that email address is the only dynamically configurable attribute and key=translation value pairs in email-address-config-custom_xx_YY.properties is lacking the ability to accept an expression and drive the value dynamically.

@james.franklin Further I would like to add that a quick test made by me has determined that the display name can't be dynamic and in-fact whatever translation value (be it a expression or constant or hard coded value) you provide in properties file appears as the display name in the email. I am not sure if I missed anything, but that's what I was ended up with.

Thanks for the input guys, for the time being a static value should be fit for purpose. I was just surprised this was the case as when sending as the process initiator the user name appears correctly in front of the mail address. Maybe this is being handled by outlook interpreting the base email address and domain from the mail header. Given time constraints I think I will run with the fixed value and leave further investigation for another day.
Thanks, James
