How do I make mail for a mailbox forward to another address as well?
Our customers sometimes ask something like this: "We've created an email mailbox for our salesperson, Robert, at firstname.lastname@example.org. But any mail sent to that address also needs to go to Robert's boss, Mollie, at email@example.com. How do we forward the firstname.lastname@example.org mail to Mollie as well?"
To do this, simply put the address in both the "POP/IMAP/Webmail Mailboxes" and "Forwarding Addresses" sections of your email options.
For example, if the address already exists as a mailbox, choose "Add Forwarding Address", type the same address that already exists in the mailbox section, and create forwarding destinations for it.
Similarly, if the address already exists as a forwarding address, you can choose "Add Mailbox" and type the same address that already exists in the forwarding section.
