Yes, you can point an email alias to multiple addresses.
To assign an email alias to multiple addresses, simply separate them with a comma. Make sure there's no space. For example, to have the alias info to two email accounts, you would simply place "firstname.lastname@example.org,email@example.com" in the email address field (without quotes) as though it were a single address. Our servers will then forward your email to both accounts.
Congratulations! You have successfully created an email alias pointed to multiple addresses!
