Mail looses e-mail aliases when upgrading from 10.10 to 10.11

Number:rdar://22931082 Date Originated:01-Oct-2015
Status:Open Resolved:
Product:Mail Product Version:9.0 (3094)
Classification:Dataloss Reproducible:Did not try
In previous versions of Mail it was possible to configure aliases for the same e-mail account by adding them as a comma separated list to the text field "e-mail address".

After the upgrade to 10.11 and Mail 9.0 e-mail aliases can now be configured using a popup menu.
The previously configured aliases are not migrated to the popup menu. Instead they are completely lost.

Steps to Reproduce:
1. Configure e-mail aliases using a comma separated list in the "Email Address" text field in Mail on OS X 10.10 as explained here:
2. Upgrade to 10.11 (Mail 9.0)

Expected Results:
Aliases are migrated to new "Alias" pop-up menu explained here:

Actual Results:
Alias pop-up menu only contains the first e-mail address from the "e-mail address" text field on 10.10. The previously configured aliases are lost.

I'm a heavy user of e-mail aliases. I use a different e-mail alias for nearly every service/company with a catch all account on my private domain. While it is certainly possible to reconfigure the lost aliases whenever responding to an e-mail from an alias that was lost, it is unnecessary work that could have been prevented by adding migration code from the comma separated list to the new pop-up.

Apple Script as a work around to migrate aliases from old still existing ~/Library/Mail/V2/MailData/Accounts.plist to Mail 9.0
