MTA is rejecting all incoming mails due to blacklisting from

Since yesterday, all incoming external mails are rejected due to "RBL listing". However like they are not on any RBL if I check.

This happens on both independent XG 19.0.1 I am using (Home Edition)

Could the reason be a malfunctioning SASI update?

Disabling RBL checks altogether lets the mails flow in again.
