In your RCPT ACL:

Uncomment that. It's a first line of defence against incoming mail from
nonexistent domains. In the raw form, like this, all that is verified is
the existence of the sending domain.

Also you have:

> # require verify = recipient/callout=10s,defer_ok


Make that

require verify = recipient

Again, it'll run the routers in verify mode and ensure that either a
local delivery will succeed, or a remote one is possible. You can add
the callout again later with suitable restrictions so you don't
arbitrarily callout to every domain under the sun (this is a
long-discussed and oft-discussed issue).

Then restart Exim.
