Context: let's say I have the domain
example.com, but the registrar doesn't provide an "email forward" system.
How can I configure
postfix (or even a simple Python script would be better, because I could customize certain forwarding rules) to use my server of IP 18.104.22.168 as a server that only redirects every mail incoming to
*@example.com ("catch-all") to
The DNS record would probably be something like:
mx.example.com MX mailforwarder.example.com mailforwarder.example.com A 22.214.171.124
