DNSBL
DNSBL helps control whether your mail server has been listed in anti-spam system blacklists.
This task type requires the PRO plan.
When to use
- When the server sends mail and it's important to notice reputation deterioration in time.
- When you want to monitor the risk of email delivery issues.
When to choose another type
- If you are checking website blocks in safe DNS or government registries, it's better to use the corresponding task types.
- If you are interested in website availability, choose HTTP.

When the alert will trigger
The alert will trigger if the specified server or IP is found in at least one of the selected DNSBL lists.
Notification settings
For each notification channel in the task, you can set additional parameters. They only apply to DOWN events.
| Parameter | What it does |
|---|---|
| Enabled | Allows or prohibits sending notifications through this channel for this task. |
| Delay by PRO | Delays the first DOWN notification by the selected time (up to 12 hours). Convenient to avoid alerts for short-term failures. |
| Repeat after PRO | Periodically repeats the notification while the task remains in DOWN status (up to 1 hour between repeats). Suitable when it's important not to miss a prolonged failure. |
The "Delay" and "Repeat" parameters do not affect UP events and recovery notifications.
