In Mail.app I can send e-mails on behalf of different mail addresses. It looks like this:
enter image description here

I've achieved this by inputting multiple e-mail addresses separated by a comma in the Email Address field of the Account information in the Preferences.

I can also select a full name in the mail preferences: enter image description here

However, any name I input there is the same for all three reply-from e-mail addresses.

How can I set a name for each reply-from e-mail address?

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.

Here is a preview of this in the Xcode plist editor.

  • Sounded good, but unfortunately doesn't work. The reply-from drop down list still only shows the e-mail addresses inputted in the Email Address field without any name. The EmailAliases doesn't seem to have any effect. Feb 24, 2014 at 22:27
  • I missed an important point. The EmailAliases Array must be in MailAccounts > Item # where Item # is the account to which you want to link the new aliases. Feb 24, 2014 at 22:31
  • Yes, it works now! Thank you for your prolonged attention! Oh, and just a small detail: the string field names are name and alias (as in your screenshot). Not aliases as you write in the fourth point. It's too small for me to edit it, could you please change it so future users don't get confused? Feb 25, 2014 at 0:19

  • I recently upgraded to Mac OS 10.11 and it stopped working. However, the file still incorporates the proposed changes, but the names are not listed anymore. It is also discussed here: forums.developer.apple.com/thread/3881
