Enhance mail-log-analyzer.sh with sophisticated blacklist detection
- Replace basic blacklist patterns with comprehensive detection engine
- Use same detection patterns as email-diagnostics.sh (26+ providers)
- Improved provider recognition: Spamhaus, SpamCop, Barracuda, Gmail, Microsoft, Yahoo, SORBS, CBL
- Add severity-based recommendations:
- CRITICAL: >100 rejections (immediate action needed)
- WARNING: 10-100 rejections (review and analyze)
- INFO: <10 rejections (monitor and track)
- Better guidance with cross-references to blacklist-check tool
- Extract and track specific provider names, not just generic RBLs
Detection coverage expanded from basic patterns to:
- Error codes: S3150, S3140, AS(48xx), CS01
- Gmail reputation patterns
- Microsoft/Outlook specific patterns
- All major email provider block messages
- Traditional RBL queries and responses
Recommendations now include:
- Tool suggestions (blacklist-check, email-diagnostics)
- Severity assessment based on rejection count
- Actionable next steps for resolution
mail-log-analyzer now provides deeper analysis of blacklist
issues identified in mail logs, helping administrators quickly
identify systemic listing problems vs. one-time incidents.
