+    Enable X509_V_FLAG_TRUSTED_FIRST by default in the legacy verifier.
+    
+    In order to work around the expired DST Root CA X3 certficiate, enable
+    X509_V_FLAG_TRUSTED_FIRST in the legacy verifier. This means that the
+    default chain provided by Let's Encrypt will stop at the ISRG Root X1
+    intermediate, rather than following the DST Root CA X3 intermediate.
+    
+    Note that the new verifier does not suffer from this issue, so only a
+    small number of things will hit this code path.
