-This repo exists to automatically capture any releases of the SaaS edition of SimpleLogin. It checks once a day, and builds the latest one automatically if it is newer than the currentlty built version.
+I did this to simplify deployment of my self-hosted SimpleLogin instance. SimpleLogin do not provide an up-to-date version for self-hosting, leaving you with the options of either running a very outdated version with no app support, a beta version, or their `simplelogin/app-ci` version. This last option works well if you use an x86 machine, but I'm running SimpleLogin on an ARM machine. Since I don't want to have to build containers on the machine itself, this repo handles that for me.
 
-This exists to simplify deployment of SimpleLogin in a self-hosted capacity, while also allowing the use of the latest version; SimpleLogin do not provide an up-to-date version for this use.
-
-The image is built for amd64 and arm64 devices.
+As a result, this image is built for both amd64 and arm64 devices.

 ```
+
+## Additional security measures
+
+For additional security, we recommend you take some extra steps.
+
+### Enable Certificate Authority Authorization (CAA)
+
+[Certificate Authority Authorization](https://letsencrypt.org/docs/caa/) is a step you can take to restrict the list of certificate authorities that are allowed to issue certificates for your domains.
+
+Use [SSLMate’s CAA Record Generator](https://sslmate.com/caa/) to create a **CAA record** with the following configuration:
+
+- `flags`: `0`
+- `tag`: `issue`
+- `value`: `"letsencrypt.org"`
+
+To verify if the DNS works, the following command
+
+```bash
+dig @1.1.1.1 mydomain.com caa
+```
+
+should return:
+
+```
+mydomain.com.	3600	IN	CAA	0 issue "letsencrypt.org"
+```
+
+### SMTP MTA Strict Transport Security (MTA-STS)
+
+[MTA-STS](https://datatracker.ietf.org/doc/html/rfc8461) is an extra step you can take to broadcast the ability of your instance to receive and, optionally enforce, TSL-secure SMTP connections to protect email traffic.
+
+Enabling MTA-STS requires you serve a specific file from subdomain `mta-sts.domain.com` on a well-known route.
+
+Create a text file `/var/www/.well-known/mta-sts.txt` with the content:
+
+```txt
+version: STSv1
+mode: testing
+mx: app.mydomain.com
+max_age: 86400
+```
+
+It is recommended to start with `mode: testing` for starters to get time to review failure reports. Add as many `mx:` domain entries as you have matching **MX records** in your DNS configuration.
+
+Create a **TXT record** for `_mta-sts.mydomain.com.` with the following value:
+
+```txt
+v=STSv1; id=UNIX_TIMESTAMP
+```
+
+With `UNIX_TIMESTAMP` being the current date/time.
+
+Use the following command to generate the record:
+
+```bash
+echo "v=STSv1; id=$(date +%s)"
+```
+
+To verify if the DNS works, the following command
+
+```bash
+dig @1.1.1.1 _mta-sts.mydomain.com txt
+```
+
+should return a result similar to this one:
+
+```
+_mta-sts.mydomain.com.	3600	IN	TXT	"v=STSv1; id=1689416399"
+```
+
+Create an additional Nginx configuration in `/etc/nginx/sites-enabled/mta-sts` with the following content:
+
+```
+server {
+	server_name mta-sts.mydomain.com;
+	root /var/www;
+	listen 80;
+
+	location ^~ /.well-known {}
+}
+```
+
+Restart Nginx with the following command:
+
+```sh
+sudo service nginx restart
+```
+
+A correct configuration of MTA-STS, however, requires that the certificate used to host the `mta-sts` subdomain matches that of the subdomain referred to by the **MX record** from the DNS. In other words, both `mta-sts.mydomain.com` and `app.mydomain.com` must share the same certificate.
+
+The easiest way to do this is to _expand_ the certificate associated with `app.mydomain.com` to also support the `mta-sts` subdomain using the following command:
+
+```sh
+certbot --expand --nginx -d app.mydomain.com,mta-sts.mydomain.com
+```
+
+## SMTP TLS Reporting
+
+[TLSRPT](https://datatracker.ietf.org/doc/html/rfc8460) is used by SMTP systems to report failures in establishing TLS-secure sessions as broadcast by the MTA-STS configuration.
+
+Configuring MTA-STS in `mode: testing` as shown in the previous section gives you time to review failures from some SMTP senders.
+
+Create a **TXT record** for `_smtp._tls.mydomain.com.` with the following value:
+
+```txt
+v=TSLRPTv1; rua=mailto:YOUR_EMAIL
+```
+
+The TLSRPT configuration at the DNS level allows SMTP senders that fail to initiate TLS-secure sessions to send reports to a particular email address.  We suggest creating a `tls-reports` alias in SimpleLogin for this purpose.
+
+To verify if the DNS works, the following command
+
+```bash
+dig @1.1.1.1 _smtp._tls.mydomain.com txt
+```
+
+should return a result similar to this one:
+
+```
+_smtp._tls.mydomain.com.	3600	IN	TXT	"v=TSLRPTv1; rua=mailto:tls-reports@mydomain.com"
+```
