for Google Workspace / for Microsoft 365
为了让我们的系统保持稳定的状态，HENNGE Email DLP 的服务有分别各别环境的整体寄信限制和用户个人的寄信限制。
无论您使用的系统是 Google Workspace 或是 Microsoft 365 ，信件寄送是内部或是外部，以下的限制都是一致的。
如果用户的寄信量或是整体环境的寄信量超过了以下的规范限制，Email DLP 服务会寄送错误讯息至您的 Google Workspace 或是 Microsoft 365。
谢谢您体谅我们为维护系统所设定的需求。
如果您有任何问题，欢迎来信 (tw-support@hennge.com) 连络我们。

(*1)HENNGE Email DLP 服务会分析每封电子邮件里面的收件者，如果同一封信件有三个收件地址，则为三封电子邮件。
(*2) 如果用户在短时间内寄送大量的信件，信件服务器（如 Google Workspace、Microsoft 365 等服务）和垃圾邮件过滤服务（RBL 黑名单）有可能把我们的 IP 位址列如电子邮件的黑名单并标记为垃圾邮件。这可能会影响到我们的服务和使用我们服务的其它用户的权益。
