This is a bad idea. Just waiting for an accident where you suddenly
become a relay for say hotmail.com, just because you may need to tune
a transport entry for this destination.
This also makes all domains in the transport table local, with their
sub-domains implicitly designated as relay domains (default relay_domains
= $mydestination). This also means that your recipient validation is wrong,
because you want local_recipient_maps not relay_recipient_maps for most
domains.

The transport table is performance critical, I recommend virtual(5)
instead and either no transport table at all, or just one that
special-cases a few domains. Per-user transport is available and robust
(no mail silently lost), but especially over MySQL/LDAP/PgSQL/... not
highly performant and too prone to outages and so is not recommended
(by me).

This mixing of address classes is often bogus. Use virtual_mailbox_domains
for virtual mailboxes.

Use virtual_mailbox_domains, not transport_maps to define which domains
are delivered to virtual users. Or use "mailbox_transport" via local(8).

It has problems, you just have not found them yet.
