+# Mailcow Email Server on NC1
+
+**Status:** Blocked - Awaiting NC1 cleanup + Frostwall  
+**Priority:** Tier 2 - Major Infrastructure  
+**Time:** 2-3 hours  
+**Location:** NC1 Charlotte (216.239.104.130)  
+**Last Updated:** 2026-02-16
+
+## Overview
+Deploy Mailcow email server on NC1 for professional @firefrostgaming.com addresses. Self-hosted, full control, eliminates Plesk accessibility nightmare.
+
+## Why NC1
+- $0/month vs $10/month VPS ($120/year saved)
+- Geographic redundancy (Email NC, AI TX)
+- Clean IP confirmed by Breezehost
+- Monster hardware (32-core EPYC)
+- 46GB storage available after cleanup
+- GRE tunnel protects email IP from game traffic
+
+## Resources
+- RAM: 6GB Mailcow / 251GB total = 2.4%
+- Storage: 30GB Mailcow / 46GB free = 65% used
+- CPU: Massive overkill
+
+## Deployment Steps
+1. Deploy Mailcow via Docker (Postfix, Dovecot, SOGo, Rspamd, ClamAV)
+2. Configure DNS (MX, SPF, DKIM, DMARC)
+3. Create 10-15 initial addresses
+4. Test deliverability (Gmail, Outlook, Yahoo)
+5. Check spam scores/blacklists
+6. Migrate off Plesk
+
+## Success Criteria
+- ✅ Professional email operational
+- ✅ Self-hosted, full control
+- ✅ Plesk eliminated
+- ✅ $120/year saved
+
+**Blocks:** NC1 cleanup ✅, Frostwall Protocol
