SMTP Allowlist Tools
💡
SMTP tools require a paid plan.
By default, outbound SMTP (ports 25, 465, 587) is blocked for all agents to prevent spam abuse.
smtp_allowlist lets you permit outbound SMTP to specific trusted mail server hosts.
smtp_allowlist
Manage your SMTP outbound allowlist — add entries, list them, or remove them.
| Parameter | Type | Required | Description |
