This is likely the RCPT acl (because the RCPT is rejected).
It would be more than helpful to get access to your configuration, as a
starting point to the RCPT acl at least.
The deferral can be caused by any kind remote lookup (DNS, *SQL, LDAP,
…) or by any action that causes such a lookup (e.g. "verify = …" acl
condition).

Depends on you tried to reproduce it.

If logging isn't enough, you can get even more information with
debugging output. But in the actual case I don't think it's necessary.
