Ability to reroute subdomains emails like Cloudflare

[bermudi]

Cloudflare allows the use of wildcard subdomains to follow the same forwarding rules as the main domain without having to manually add them.

For example:

hello@custom.tld and hello@sub.custom.tld are equivalent.

This allows the creation of on the fly addresses like contact@[random-prefix].custom.tld.

Thanks.
