mailcow dockerized comes with a snakeoil CA "mailcow" and a server certificate in `data/assets/ssl`. Please use your own trusted certificates.
|
|
|
|
mailcow uses 3 domain names that should be covered by your new certificate:
|
|
|
|
- ${MAILCOW_HOSTNAME}
|
|
- autodiscover.**example.org**
|
|
- autoconfig.**example.org**
|
|
|
|
### Let's Encrypt

|
This is just an example of how to obtain certificates with certbot. There are several methods!
|
|
|
|
1\. Get the certbot client:
|
|
``` bash
|
|
wget https://dl.eff.org/certbot-auto -O /usr/local/sbin/certbot && chmod +x /usr/local/sbin/certbot
|
|
```
|
|
|
|
2\. Make sure you set `HTTP_BIND=0.0.0.0` and `HTTP_PORT=80` in `mailcow.conf` or setup a reverse proxy to enable connections to port 80. If you changed HTTP_BIND, then rebuild Nginx:
|
|
``` bash
|
|
docker-compose up -d
|
|
```
|
|
|
|
3\. Request the certificate with the webroot method:
|
|
``` bash
|
|
cd /path/to/git/clone/mailcow-dockerized
|
|
source mailcow.conf
|
|
certbot certonly \
|
|
--webroot \
|
|
-w ${PWD}/data/web \
|
|
-d ${MAILCOW_HOSTNAME} \
|
|
-d autodiscover.example.org \
|
|
-d autoconfig.example.org \
|
|
--email you@example.org \
|
|
--agree-tos
|
|
```
|
|
|
|
**Remember to replace the example.org domain with your own domain, this command will not work if you dont.**
|
|
|
|
4\. Create hard links to the full path of the new certificates. Assuming you are still in the mailcow root folder:
|
|
``` bash
|
|
mv data/assets/ssl/cert.{pem,pem.backup}
|
|
mv data/assets/ssl/key.{pem,pem.backup}
|
|
ln $(readlink -f /etc/letsencrypt/live/${MAILCOW_HOSTNAME}/fullchain.pem) data/assets/ssl/cert.pem
|
|
ln $(readlink -f /etc/letsencrypt/live/${MAILCOW_HOSTNAME}/privkey.pem) data/assets/ssl/key.pem
|
|
```
|
|
|
|
5\. Restart affected containers:
|
|
```
|
|
docker-compose restart postfix-mailcow dovecot-mailcow nginx-mailcow
|
|
```
|
|
|
|
When renewing certificates, run the last two steps (link + restart) as post-hook in a script.
