How to delete unwanted Sender (me) addresses in OS X Mail

contactsemailmail.app

I have a few email addresses in the dropdown list of Senders (i.e., my own email addresses that I send mail From) which are obsolete. One of them includes the string "4Q2delist@mac.com" which I never had as part of any email address.

Anyway, I want to delete these outdated email addresses from this list. NOTE: the list I am referring to is not the "recent recipients" list – it's the list of my own email addresses.

Does anyone know how to do this, or know what "4Q2delist" means, or where this file (presumably a property list) is located?

I'm on OS X Yosemite 10.10.4, Mail 8.2. Removing aliases in iCloud didn't do anything.

In Mail.app go to Preferences → Accounts → Alias

Then select Edit Aliases in the drop down list:

It should take you to icloud.com mail settings where you can edit them all:
