Im running Mavericks on a mid-2012 MBP. Finally took the plunge and moved my data over there from a mid-2010 MBP running Lion. Maybe I had this problem before and maybe not, but anyway I have it now: Some of my incoming mail displays just my name, like Jane Doe or Doe Jane in the to column. I used to see Jane Doe firstname.lastname@example.org or just email@example.com and that is what I want now. I dont want just my name showing up in the to column, I want AT LEAST the email address to which the mail was sent, if not also the name which actually matters far less. Like lots of people, I have multiple email addressses so I always want to see to which a mail was sent when I look at any of my mail messages. Im using the classic layout preference for the viewing window but even if I dont, I still have this problem. Turning on or off smart addresses doesnt make any difference. Even when I put all headers as my viewing preference (which it certainly is NOT), I only see the to email address in the X-apparently-to field when the to column of a mail only displays my name. Is there some way to fix this display attribute as a default by using some terminal command? I always want to see the "to" email address in my mails.
