Forwarding email for an entire domain I recently acquired the .com of my company name; previously been using .net domain.

I don’t want to switch emails from  .net, is it possible to setup anything at my .com to forward to my .net transparently?

I.E. somebody emails sales@mycompany.com and it forwards the message to sales@mycompany.net keeping the original sender name and address.
depending of the registar and where your email server is you can. For example Ionos (ex 1and1) allow user to redirect any un-existing email to another email. This is done with the wildcard *@yourdomainname.ext
