If this is for you iCloud account, log into your account.
Go to icloud.com/#mailand sign in using your Apple ID (the one you use with iCloud) or your @icloud.com email address (not an alias).
Click on the gear in the bottom left of window. Select Preferences.
Click on Accounts
You will see your alias account listed.
In Mail > Preferences > Accounts select your iCloud account.
Check under the Popup that you see the same alias accounts.
If all is set correctly, delete the account in Mail THEN add it back.
Let me know if this helps.
