Delete a saved SMTP profile. Domains using it are reassigned automatically (to managed SMTP on paid plans, otherwise not_configured). Requires TREKMAIL_ALLOW_DESTRUCTIVE=true.
AI agents call delete_domain_smtp_profile to permanently remove resources in TrekMail MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly deletes SMTP profile data with organizational impact—domains lose their configured mail handling and revert to defaults. While not data loss in the traditional sense, SMTP profile deletion is an unrecoverable infrastructure change that affects email delivery. The explicit DESTRUCTIVE flag requirement confirms the security model categorizes this as destructive.
From the tool's definition Tool description explicitly states 'Delete a saved SMTP profile' and requires 'TREKMAIL_ALLOW_DESTRUCTIVE=true' environment variable to execute, indicating irreversible deletion of infrastructure configuration.
