Our DMARC report is showing that email was sent from the domain @blackbaudmail.netcommunity1.com. Is this a problem?
There is no cause for concern as this is the built-in email domain for Blackbaud NetCommunity and BBIS to use as an asynchronous (async) bounce handler. An async bounce is when the recipient server accepts the email at first and then later rejects it. It then sends an email to the bounce handler with the error. The bounce handler then marks the email as a bounce (instead of the original success).
