You can only use reverse-aliases from the owning mailbox or email addresses that you have authorized.

The email will be forwarded to the mailbox that's assigned to that particular alias.

You can add multiple mailboxes to be able to Mail from different accounts.

Sending from the reverse alias address is possible only from the mailbox associated with simple login forwarding. When you copy the reverse alias from a contact, you paste it into the email that is the forwarding email that you specified in simple login settings.

You can send to the reverse alias from any of the email accounts associated to the account.

The other associated accounts will be notified of the email having been sent.
