450 4.1.2 <user@valid.tld>: Recipient address rejected: Domain not found

[ivdok]

I've spent an hour trying to fix this, and I already hate PMG.

1. Neither mail.domain.tld nor domain.tld in "Default Relay" fix this error.
2. "Relay Domains" have both mail subdomain and main domain - same shit.
3. "Transports" has both set up relaying to local Exchange DAG, but even keeping only mail.domain.tld or domain.tld doesn't change SHIT.

So how can I recommend a product for purchasing to the C-levels if it's broken as fuck?
