They are amending the API on Monday, does anyone have a 5 mile high view on whether Discourse sites that use SparkPost will be affected?:
" As a reminder, and as outlined in this [blog post](http://page.messagesystems.com/NL00vS8u000m3qD0uC80i1f), we will make suppression checks asynchronously on incoming messages. As a result, the response in both the REST Transmissions API and the SMTP API will change as follows:
SMTP API
- Current: return a ‘250 Ok’ and ‘policy rejection’ event (no injection event)
- Future: return a ‘250 Ok’ with ‘injection’ event followed by a ‘bounce’ event
Transmissions REST API
Single recipient
- Current: return a 400 with special error message, followed by a ‘generation rejection’ event
- Future: return a 200 with an ‘injection’ event followed by a ‘bounce’ event
Multiple recipient
- Current: return a 200 followed by a ‘generation rejection’ event (no injection event)
- Future: return a 200 with an ‘injection’ event followed by a ‘bounce’ event
When a bounce is generated due to suppression, the webhook will have bounce\_class of “25” and an error\_code of “554” and reason of “Recipient address was suppressed due to customer policy” or “Recipient address was suppressed due to system policy”."

You’re sending via smtp, not the API, right? So the API doesn’t matter.

Ah Thanks. Wasn’t sure if what they mean by “SMTP API” is their SMTP interface … forgive me, not an expert and didn’t know what discourse is doing under the hood with the SMTP credentials …
Ah, this could be a good description of the difference:
