想了解下关于邮件报警的几个问题，求解答

1、设置报警阈值的时候，600、60、ERROR,EXCEPTION都是固定的参数么？有什么区别？异常、延迟、Position超时、Process超时都应该写多少合适？
2、manager配置文件中端口可以用25么？
3、manager配置文件中可以用企业邮箱么？
求解答，多谢

Begin with the manager configuration and mail-alert threshold handling; trace where 600, 60, ERROR, and EXCEPTION are consumed. Verify supported ports and enterprise-mail settings, then document the distinctions, recommended timeout values, and configuration constraints so each question has an explicit answer.
