# Mailu with Let's Encrypt Using Docker Compose
📙 The complete installation guide is available on my [website](https://www.heyvaldemar.com/install-mailu-using-docker-compose/).
❗ Change variables in the `.env` to meet your requirements.
To generate a 128-bit security key for the `SECRET_KEY` variable, use the following OpenSSL command:
`openssl rand -hex 16`
💡 Note that the `.env` file should be in the same directory as `mailu-traefik-letsencrypt-docker-compose.yml`.
Set up the following DNS and firewall configurations for our Mailu email server on yourdomain.com:
## DNS Records
### A Records
- `mailu.yourdomain.com` → `[Server IP]`
- `admin.mailu.yourdomain.com` → `[Server IP]`
- `webmail.mailu.yourdomain.com` → `[Server IP]`
- `webdav.mailu.yourdomain.com` → `[Server IP]`
- `traefik.mailu.yourdomain.com` → `[Server IP]`
### MX Record
- `yourdomain.com MX` → `mailu.yourdomain.com (Priority: 10)`
### SPF Record
- `TXT yourdomain.com` → `v=spf1 a mx ~all`
### DKIM Record
- `TXT mail._domainkey.yourdomain.com` → `(DKIM Key)`
### DMARC Record
- `TXT _dmarc.yourdomain.com` → `v=DMARC1; p=none; rua=mailto:[email protected]`
### PTR Record
- `[Server IP]` → `mailu.yourdomain.com`
### Firewall Ports to Open
- **SMTP:** 25, 465, 587
- **IMAP/POP3:** 143, 993, 110, 995
- **Sieve:** 4190
- **Web Traffic:** 80, 443
Replace `[Server IP]` and `(DKIM Key)` with the appropriate values for your server.
Create networks for your services before deploying the configuration using the commands:
`docker network create traefik-network`
Deploy Mailu using Docker Compose:
`docker compose -f mailu-traefik-letsencrypt-docker-compose.yml -p mailu up -d`
## Administrator Account
Set password for administrator account. Replace `PASSWORD` with a strong, secure password:
`docker compose -p mailu exec admin flask mailu admin admin yourdomain.com PASSWORD`

hey everyone,
💾 I’ve been in the IT game for over 20 years, cutting my teeth with some big names like [IBM](https://www.linkedin.com/in/heyvaldemar/), [Thales](https://www.linkedin.com/in/heyvaldemar/), and [Amazon](https://www.linkedin.com/in/heyvaldemar/). These days, I wear the hat of a DevOps Consultant and Team Lead, but what really gets me going is Docker and container technology - I’m kind of obsessed!
💛 I have my own IT [blog](https://www.heyvaldemar.com/), where I’ve built a [community](https://discord.gg/AJQGCCBcqf) of DevOps enthusiasts who share my love for all things Docker, containers, and IT technologies in general. And to make sure everyone can jump on this awesome DevOps train, I write super detailed guides (seriously, they’re foolproof!) that help even newbies deploy and manage complex IT solutions.
🚀 My dream is to empower every single person in the DevOps community to squeeze every last drop of potential out of Docker and container tech.
🐳 As a [Docker Captain](https://www.docker.com/captains/vladimir-mikhalev/), I’m stoked to share my knowledge, experiences, and a good dose of passion for the tech. My aim is to encourage learning, innovation, and growth, and to inspire the next generation of IT whizz-kids to push Docker and container tech to its limits.
Let’s do this together!
