Hi,

Emails sent to a few of our users are generating the following NDRs:

Delivery has failed to these recipients or distribution lists:

Your message wasn't delivered because of security policies. Microsoft Exchange will not try to redeliver this message for you. Please provide the following diagnostic text to your system administrator.

The following organization rejected your message: mail.rollernet.us.

Any idea why this is happening?

No way to tell, not enough information. The sender and recipients can't be redacted and we need full headers. It's obviously an SPF policy issue, but the only way to tell is by looking at the sender domain's SPF records and comparing it to the sender IP.
