I've been trying to solve this but can't seem how to do it, let alone if its possible; So in my address book I have a contact saved, lets say saved as 'Mr. Joe Bloggs' with email eg. email@example.com. However when Mr. Joe Bloggs sends me an email, in Mail it says sender as 'J.J. Bloggs' (with email firstname.lastname@example.org), probably the way Joe wants his name to be viewed in the recipients inbox. Even though its the same email address, is there any way that when I receive an email, it displays the Contact name (Mr. Joe Bloggs) I have associated with that email instead of what the sender wants? Take an example where two people send me emails, with their sender names both as J.J Bloggs, but different email addresses. If I have their names saved differently it would help a lot in differentiating between them in my inbox. Obviously this only applies to senders who I have information saved in Address Book. Thanks for any info, b.
