- 1 个 dispatcher + N 个 worker 池（默认 4）并行投递，启动时立即 扫描清空积压；workers=0/1 退化为串行（旧行为） - 每收件域并发信号量（默认 2，配置 max_concurrent_per_domain）， 防对单个 MX 域并发过多被判定滥发；中继模式统一按 relay 限制 - store 新增 Claim 原子抢占（sending 状态防重复投递），并发下 每封邮件恰好投递一次 - 新增配置 workers/batch_size（替代硬编码 50）；dispatcher 改为 抢占后投递、worker 只负责发送，退避重试/退信/状态机不变 - 新增测试：真并发、串行回退、每域上限、临时/永久失败、错误隔离、 Claim 并发原子性与状态可抢占性；-race 无警告
