DMARC record validation now checks reporting URI format

DMARC record validation now detects malformed rua and ruf reporting destinations.

The validator checks that each aggregate and failure reporting URI uses the expected mailto: format, for example mailto:reports@example.com. Invalid entries are shown as invalid tag values in the DMARC record validation section, helping you catch mistakes that could prevent reports from being delivered.

Existing DMARC records have been revalidated, so you may see a change in the record validation results if your records are invalid.
