If you create an email forwarder that forwards email to firstname.lastname@example.org, and create a POP email account of the same name – let’s call this email@example.com – then you’ll receive 2 emails. 1 will be at firstname.lastname@example.org, and 1 will be at email@example.com. This isn’t ideal though, because sometimes you’ll need a POP account to reply mails with, and so you can’t just use a pure forwarder. Some email service providers such as Gmail has a “forward and delete” functionality, and this is a behavior we can replicate. However, we can’t use the normal email forwarders. For this, we’ll need the account-level filtering function.
Go to account-level filtering in Hosting Dashboard, and then create a new filter. In the “Rules” section”, choose “Any header”, and put in your email address (e.g. firstname.lastname@example.org). Now for the “Actions” section, choose “Redirect to email”, and put in the email address that you want all these mail to go to (e.g. email@example.com).
Viola! You now have a “forward and delete” behavior for your email.
