[https://products.office.com/en-us/CMSImages/Office365Logo_Orange.png?version...] Your message to SEMPL@ccastudents.me couldn't be delivered. A custom mail flow rule created by an admin at ccaeducate.me has blocked your message. External senders are not permitted to send email to CCA student accounts webmaster Office 365 ccastudents.me Sender Action Required Blocked by mail flow rule

How to Fix It An email admin at ccaeducate.me has created a custom mail flow rule that blocks messages that meet certain conditions, and it appears that your message has met one or more of those conditions.

* Check the text above for a custom message from the email admin that may help explain why your message was blocked and how you might be able to fix it. For example, removing prohibited words from the message or sending the message from a different email account may be sufficient to deliver your message.

If you've tried and you're still not able to fix the problem, consider contacting the email admin at ccaeducate.me to discuss what to do. While they're unlikely to remove or relax the rule, if you have a legitimate need to deliver your message they may offer guidance for how to do so.

More Info for Email Admins Status code: 550 5.7.1_ETR

This error occurs because an email admin at ccaeducate.me 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 ccaeducate.me 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.
