+# Deployment Values
+
+For each deployment, you need to set the environment variables and configurations.
+Here is some specific information on how to set the values.
+
+## E-Mails
+
+You need to set environment variables to send registration and invitation information or notifications to users, for example.
+
+### SPF and DKIM
+
+More and more e-mail providers require settings for authorization and verification of e-mail senders.
+
+### SPF
+
+Sometimes it is enough to create an SPF record in your DNS.
+
+### DKIM
+
+However, if you need DKIM authorization and verification, you must set the appropriate environment variables:
+
+```bash
+SMTP_DKIM_DOMAINNAME=<your e-mail sender domain>
+SMTP_DKIM_KEYSELECTOR=2017
+SMTP_DKIM_PRIVATKEY="-----BEGIN RSA PRIVATE KEY-----\n<your base64 encoded privat key data>\n-----END RSA PRIVATE KEY-----\n"
+```
+
+You can find out how DKIM works here:
+
+<https://www.ionos.com/digitalguide/e-mail/e-mail-security/dkim-domainkeys/>
+
+To create the private and public DKIM key, see here:
