How can I parse bounce messages automatically?

Automated bounce parsing extracts actionable data:

Parsing approach:

MIME parsing: Extract multipart/report structure. DSN extraction: Parse message/delivery-status part. Field extraction: Pull Status, Diagnostic-Code, recipient. Pattern matching: Classify based on content.

Technical implementation:

Use MIME parsing library for your language. Extract delivery-status content type. Parse key-value pairs from status part. Apply regex for non-standard formats.

Classification logic:

Map SMTP codes to categories. Match diagnostic text against known patterns. Apply provider-specific rules. Default to conservative classification.

Tools and libraries:

Language-specific MIME libraries. Bounce parsing libraries (varies by language). ESP APIs often provide parsed data.

Automated parsing turns chaos into structured data. Consistent interpretation enables consistent response.
