Multi-recipient Addresses (MRAs) are groups of addresses that email is forwarded to when it is received in a specific mailbox. They work similar to Mail Forwarders, but you can forward to multiple addresses instead of just one. The top address is where mail will be received, while the recipient addresses are those that the mail will be forwarded to. Choose “Multi-Recipient Addresses” from the Domain Menu, then click “Add New” to add one.
Note – only one address can be added per line. Also, the number of addresses is restricted to 50.
