Before you deploy

On first boot, Stalwart auto-generates admin credentials and prints them to the container logs. Check the service logs to find the admin username and password. Then access the web admin at the service domain and log in. From there, configure your domain under Management > Directory > Domains, and Stalwart will generate the required DNS records (MX, DKIM, SPF, DMARC) for you. Set the correct server hostname in Settings > Server > Network. Mail ports (SMTP 25, submission 587/465, IMAP 143/993, POP3 110/995, ManageSieve 4190) are exposed for direct access.
