- New page: Dovecot IMAP vsz_limit OOM from a bloated/corrupt index.log

- fail2ban IMAP self-ban: add permanent ignoreip-whitelist fix + dynamic-IP caveat.
- firewalld mail ports: add 'submission/587 never added' variant + correct
Fedora service name; note Ansible now manages the full mail-service set.
- Index + SUMMARY updated with the new page.
- Fixed 4 broken markdown links (bad relative paths in See Also sections)
- Corrected n8n port binding to 127.0.0.1:5678 (matches actual deployment)
- Updated SnapRAID article with actual majorhome paths (/majorRAID, disk1-3)
- Converted 67 Obsidian wikilinks to relative markdown links or plain text
- Added YAML frontmatter to 35 articles missing it entirely
- Completed frontmatter on 8 articles with missing fields
