host: "smtp.mail.td",
port: 25,

자주 묻는 질문
What is SMTP Sandbox?
SMTP Sandbox is a fake SMTP server that captures all emails sent by your application. Emails are stored in your dashboard and never delivered to real recipients. It's ideal for testing email flows in development, staging, and CI/CD environments.
Does it send emails to real recipients?
No. All emails are intercepted and stored in your sandbox inbox. The SMTP server accepts any recipient address but never forwards the email. Real users will never receive test emails.
How do I authenticate?
Use SMTP AUTH PLAIN with any Pro API token as the password. The username can be anything. Create API tokens in the Pro Dashboard under API Tokens.
Do I need a Pro account?
Yes. SMTP Sandbox is a Pro feature. The Pro plan starts at $9/month and includes the sandbox, custom domains, webhooks, API tokens, and up to 100,000 mailboxes.
