More Info for Email Admins Status code: 550 5.7.1_ETR
This error occurs because an email admin at mukilteoschooldistrict.onmicrosoft.com has created a custom mail flow rule that has blocked the sender's message.
In some cases, the sender can change the message so it no longer violates the rule. However, depending on the rule's conditions, it's possible that the only way to deliver the message is to change the rule itself, and only an email admin at mukilteoschooldistrict.onmicrosoft.com can do that. Although it's possible the rule is unintentionally flawed or it's stricter than the admin intended, it may be working exactly as they want it to.
