It knows the domain already and SMTP credentials are already saved. I’ve already set creds for abc@domain.tld, xyz@domain.tld and pr course as usual I can reply, send new emails from these addresses. But I should also be able to send emails/reply from pqrs/dfg/john/tom/ram/bond/bill/etc@domain.tld. Of course reply will be automatic but sending new email might just require changing the from field. It can have a setting that “if a from address identified isn’t already added as an identity, it should use the SMTP creds of matching domain”. It won’t work for something like Gmail, Outlook.com (I mean one anyway can’t have catch-all on these domains) but would work great for personal emails. This is what I meant. Because without such a feature - catchall feature is often rendered very limited. Even iCloud+ supports replying - id you’ve to send a fresh mail from a catchall/disposable (or service/provider/business specific) email address you’re out of luck.
