cschantz a6556bd540 Apply false positive reduction filter to mail-log-analyzer.sh 
- Add same post-extraction filtering as email-diagnostics.sh
- Filter out negation keywords, question contexts, and non-RBL blocks
- Ensures consistency across all blacklist detection tools
- Prevents over-reporting of blacklist issues in mail analysis

Same exclusion patterns used:
- Negations: "not blacklisted", "delisted", "removed from"
- Questions: "check if", "if your server"
- General descriptions: "we block", "rarely", "based on sender"
- Non-RBL blocks: "firewall", "policy block", "rate limit"

This ensures mail-log-analyzer provides same high-accuracy
blacklist detection as email-diagnostics and other tools.

cschantz e47c58dc1a 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.
