This is a list of the best solutions for an email forwarding service.
Pobox is by far my favorite email forwarding service. $34 a year and I can create as many aliases as I want on all my domains and then forward the emails to my primary Office 365 email account.
ImprovMX is 100% free and great for smaller projects. Simply point your MX records and forwarding everything from one domain to any email address you want.
