Creating a Forwarder
Enable Forwarding
Check Switch on mail forwarding and enter the destination address to forward mail to.
You can forward to multiple addresses by entering each one on a separate line.
Forwarding Without Keeping a Copy
By default, Plesk can store a copy in the local mailbox while also forwarding. If you do not want to retain a local copy, disable the mailbox storage option on the same settings page.Forwarder-Only Address (No Mailbox)
If you want a forwarding address that does not have a mailbox at all (e.g.contact@example.com forwards to your personal Gmail), create the email address in Plesk, then disable the mailbox and enable forwarding as described above.
