Can you explain the DNS part? AFAIK the sender just looks for MX on the domain itself, regardless of local part.

The actual address in the email header should still contain the subdomain though.
The address "[email protected]" doesn't point to a subdomain, though, the only reference to the company is the local part of the address, and so has nothing to do with DNS.
If he said he used "[email protected]", then it's possible he has a wildcard MX record for *.example.com, but that's not at all what he said, although perhaps it's what he meant.
Regardless, the question remains unanswered.
