DMARC report corrections and normalizations are now shown in the report viewer

When an invalid DMARC reports arrives, DMARCwise applies some corrections to facilitate processing.

This includes normalizations, which are high-confidence cleanups such as lowercasing values or removing invalid punctuations, recovered fields, such as when an invalid value is replaced with a valid one when the intent is clear enough, or discards, where an empty or invalid item is removed because it’s clearly the result of a bug in the report genreator.

DMARCwise applies these corrections to avoid discarding these reports, as they would fail validation even when the errors are minor or recoverable. Normalizations also help with filtering.

This behaviour has been documented in our Reports processing reference for a while, but we now expose these corrections in the DMARC report viewer interface, as shown in the screenshot above.

When a field or section was corrected, a badge appears next to it, showing whether it’s a normalization, a recovered field, or a discard. Clicking a badge opens a dialog that lists each correction with its original and corrected value.

The original unprocessed report remains available in XML format.
