Improved accuracy:
- Bounces now only count actual SMTP delivery failures (550-554 codes)
- Excludes SMTP/IMAP/FTP authentication failures from bounce count
- Spam rejected now only counts actually rejected emails
- Excludes emails delivered to spam folder (those are successful deliveries)
- Updated display sections to match new filtering logic
This fixes the misleading "334 bounced" count that was actually
showing authentication failures, not email delivery problems.
The script now searches:
- /var/log/exim_mainlog (Exim delivery logs)
- /var/log/maillog (Dovecot auth + delivery)
- /var/log/messages (fallback)
This fixes the issue where only auth logs were found but actual
email deliveries were missed because they were in different log files.
Now properly separates delivery events from authentication events
across all log sources.
Key improvements:
- Add Quick Summary section at top for instant status
- Always show main metrics (sent/received/delivered) even if 0
- Fix contradictory "account not found" when successful logins exist
- Better verdict logic for authentication-only scenarios
- Clearer section headers ("Mailbox Access Activity" vs delivery)
- Group problems together, only show if they exist
- Improve status messages with context
Output now shows:
1. Quick Summary - instant understanding of status
2. Email Delivery Activity - always show main counts
3. Problems section - only if issues detected
4. Mailbox Access Activity - clarify IMAP/POP3 vs email delivery
5. Account Status - use successful logins as proof account exists
6. Better verdicts for auth-only, no-activity scenarios
