The deployment of Mailcow is mostly correct here. Mail protocol ports should be forwarded directly to the Mailcow server from the firewall. Traefik should only sit in front of Mailcow for web traffic, and it should pass HTTPS through transparently so Mailcow can manage and serve its own certificates.
## Purpose
The purpose of this document is to illustrate how to deploy Mailcow in a dockerized format.
!!! note "Assumptions"
It is assumed that you are deploying Mailcow into an existing Ubuntu Server environment. If you are using a different operating system, refer to the [official documentation](https://docs.mailcow.email/getstarted/install/).

### Download and Deploy Mailcow
Run the following commands to pull down the mailcow deployment files and install them with docker. Go get a cup of coffee as the `docker compose pull` command may take a while to run.

### Reverse-Proxy Configuration
For the purposes of this document, it will be assumed that you are deploying Mailcow behind Traefik for web traffic only. Traefik should pass HTTPS through transparently, allowing Mailcow to manage and serve its own certificates.

### Login to Mailcow
At this point, the Mailcow server has been deployed so you can log into it.
* **Administrators**: `https://${MAILCOW_HOSTNAME}/admin` (Username: `admin` | Password: `moohoo`)
* **Regular Mailbox Users**: `https://${MAILCOW_HOSTNAME}` (*FQDN only*)
### Mail-Client Considerations
You need to ensure that you generate an app password if you have MFA enabled within Mailcow. (MFA is non-functional in Roundcube/SoGo, you set it up via Mailcow itself). You can access it via the Mailcow configuration page: https://mail.bunny-lab.io/user, then look for the "**App Passwords**" tab.
### Running Updates
If you want to run updates, just SSH into the server, and navigate to `/opt/mailcow-dockerized` and run `./update.sh`. I recommend avoiding the IPv6 implementation section. Be patient, and the upgrade will be fully-automated.
