How to forward a mailbox to another address

Forwarding sends incoming messages to one or more other addresses.

Steps

1. Open Mail in Plesk.
2. Select the email address, then open the Forwarding tab.
3. Turn on mail forwarding.
4. Enter each destination address and save the change.
5. Send a test message from an unrelated address.

Plesk normally keeps a copy in the original mailbox unless you turn mailbox delivery off. Keeping copies can fill the mailbox, while turning delivery off means webmail will not retain them. Pick the behaviour you actually need and check the mailbox after testing.
