I've added aliases to my accounts.plist file which worked fine in Yosemite but they don't work in El Capitan.
I see that the plist file is now under ~/Library/Mail/V3/MailData/Accounts.plist and the same entries are there that were working on Yosemite, but they are just ignored.
I can add email address seperated by commas in the account setup, but that doesn't allow me to change the "send from" name.
Any ideas?
