Configuration via REST
Most users use the dashboard to manually set up an SMTPeter account. However, all configuration settings can also be set and queried using the REST API. There are for example methods to set up sender domains and to check whether your DNS records are valid.
Advanced settings
If you use SMTPeter to route all your outgoing email, you just have to set up sender domains and follow up the DNS recommendations with the methods mentioned above. This fixes all your outgoing messages. However, if you also send out mail from other IP addresses, you have to set up extra SPF settings, and you might need the private key that is currently in use.
SMTPeter automatically rotates DKIM keys, so that you never have to worry about updating your own DKIM keys or DNS records. However, the REST API supports seting up your own custom DKIM keys.
