Hi,

Sorry this is a followup after writing as there might not be sufficient
information in my OP about whats in the database:

Some sample data:

MariaDB [mailauth]> select * from bannedsenders limit 2;
+----+--------------------------------+
| id | sender                         |

+----+--------------------------------+
|  1 | communities-emailer@??? |
|  2 | reply@???          |

+----+--------------------------------+
2 rows in set (0.01 sec

Sorry for the multiple posts.

A.
