How to have multiple names in Apple Mail?

In ~/Library/Mail/V2/MailData/Accounts.plist :

  • In Root > MailAccounts > Item # where # is the account to which you want to link the new aliases.
  • Create a new Array called EmailAliases
  • In this Array add a dictionary call Item # for each name you want
  • In each dictionary you created add 2 string fields : name and alias.
  • In name you put the name and in aliases you put the mail address.
  • Restart Mail.app
  • Enjoy.
