Function IsSelfSend

internal/loopback/loopback.go:50–58

IsSelfSend reports whether req targets only the sender's own inbox — i.e., the agent is writing a note to itself. Returns true only when there's a single To recipient that matches the agent's own address (case-insensitive, trimmed) AND no Cc/Bcc — any mixed/external recipient routes through normal S

(req outbound.SendRequest, agentEmail string)

// alias-strip downstream as a self-spam guard, so doing it here is
// purely "see through" the aliases earlier.
func IsSelfSend(req outbound.SendRequest, agentEmail string) bool {
	if len(req.CC) != 0 || len(req.BCC) != 0 {
		return false
	}
	if len(req.To) != 1 {
		return false
	}
	return strings.EqualFold(strings.TrimSpace(req.To[0]), agentEmail)
}

// StripAgentSelfAliases removes case-insensitive, whitespace-trimmed
// matches of agentEmail from addrs. Used to pre-clean reply recipients
