# Runbook: mailcow health (mx2)
|
||
|
|
|
||
|
|
Target: [mx2.windy.me](../hosts/mx2.windy.me.md)
|
||
|
|
Path: `/opt/mail`
|
||
|
|
Prefer: `./scripts/check-mx2.sh` from this repo, or the steps below over SSH.
|
||
|
|
|
||
|
|
## 1. Containers
|
||
|
|
|
||
|
|
```bash
|
||
|
|
ssh windy@mx2.windy.me 'cd /opt/mail && docker compose ps -a'
|
||
|
|
```
|
||
|
|
|
||
|
|
Expect mailcow (`cow-*`) services **Up**. Note any Exit/Restarting.
|
||
|
|
|
||
|
|
## 2. Watchdog
|
||
|
|
|
||
|
|
```bash
|
||
|
|
ssh windy@mx2.windy.me 'cd /opt/mail && docker compose logs --tail=40 watchdog-mailcow'
|
||
|
|
```
|
||
|
|
|
||
|
|
Expect recent lines at **100%** for Nginx, Postfix, Dovecot, MySQL, Redis, SOGo, Rspamd, ACME, etc.
|
||
|
|
|
||
|
|
## 3. Queue
|
||
|
|
|
||
|
|
```bash
|
||
|
|
ssh windy@mx2.windy.me 'cd /opt/mail && docker compose exec -T postfix-mailcow postqueue -p'
|
||
|
|
```
|
||
|
|
|
||
|
|
Healthy: empty / `Mail queue is empty`.
|
||
|
|
|
||
|
|
## 4. Local listeners
|
||
|
|
|
||
|
|
```bash
|
||
|
|
ssh windy@mx2.windy.me 'ss -tlnp | grep -E ":(25|465|587|143|993|995|80|443|4190)\\s"'
|
||
|
|
```
|
||
|
|
|
||
|
|
## 5. External checks (from laptop / agent host)
|
||
|
|
|
||
|
|
```bash
|
||
|
|
curl -sI --max-time 10 http://mx2.windy.me/ | head -5
|
||
|
|
curl -skI --max-time 10 https://mx2.windy.me/ | head -15
|
||
|
|
echo | openssl s_client -connect mx2.windy.me:443 -servername mx2.windy.me 2>/dev/null \
|
||
|
|
| openssl x509 -noout -subject -issuer -dates
|
||
|
|
timeout 8 bash -c 'exec 3<>/dev/tcp/mx2.windy.me/25; echo -e "EHLO test.local\r\nQUIT\r\n" >&3; cat <&3' | head -20
|
||
|
|
```
|
||
|
|
|
||
|
|
Expect: HTTP 301 → HTTPS; HTTPS 200; LE cert for `mx2.windy.me`; SMTP banner `Postcow`.
|
||
|
|
|
||
|
|
## 6. DNS summary
|
||
|
|
|
||
|
|
Use a public resolver if the local stub is flaky (WSL `127.0.0.53`):
|
||
|
|
|
||
|
|
```bash
|
||
|
|
dig @1.1.1.1 +short mx2.windy.me A
|
||
|
|
dig @1.1.1.1 +short mx2.windy.me AAAA
|
||
|
|
dig @1.1.1.1 +short -x 194.163.160.244
|
||
|
|
dig @1.1.1.1 +short windy.me MX
|
||
|
|
dig @1.1.1.1 +short windy.me TXT | grep -i spf
|
||
|
|
```
|
||
|
|
|
||
|
|
## Scheduled local check
|
||
|
|
|
||
|
|
The sanitized Ansible health profile is `mailcow` (`ansible/playbooks/healthchecks.yml`). It preserves the existing standalone `scripts/check-mx2.sh` as the richer operator check, while the server-local timer emits a sanitized result at `/var/lib/vps-health/latest.json`. Neither check changes Mailcow configuration or service state.
|
||
|
|
|
||
|
|
## Pass criteria
|
||
|
|
|
||
|
|
- Compose stack up; watchdog ~100%
|
||
|
|
- Queue empty (or explain backlog)
|
||
|
|
- TLS valid; mail ports reachable externally
|
||
|
|
- A/AAAA/PTR/MX consistent with [host facts](../hosts/mx2.windy.me.md)
|
||
|
|
|
||
|
|
Update the **Verified** line on the host page after a successful check.
