Hello @LotusJeff

Did you have a look at these settings, as I think they will get you some part of the way there:

Configure these settings in **`/admin/settings/`**

| **Setting** | **Suggested Value** | **Effect** |
| --- | --- | --- |
| `purge_unactivated_users_grace_period_days` | **1** | Deletes unactivated accounts in 1 day instead of 14. It is’t instant like asked in #2, but it’s the same effect with a smaller delay. |
| `blocked_email_domains` | Add known spam TLDs/domains manually | Blocks registration from known offenders |

For anything fully automated like you ask, I think a plugin would need to be built (or none exists afaik), or you can take a look at the [new workflow feature](https://meta.discourse.org/t/discourse-workflows/407100). I don’t know if what you want is possible yet, but it’s updating almost daily so who knows 🙂

For the plugin route, there is an event you could hook in `DiscourseEvent.on(:email_bounce)`

Also worth looking at [Configure VERP to handle bouncing e-mails](https://meta.discourse.org/t/configure-verp-to-handle-bouncing-e-mails/45343) maybe
