{% hint style="info" %}
Discarding mail initiates a pause on the mail queue and deletes all newly injected mail during the discard process. Pausing the mail queue without a discard preserves all messages until the queue has been resumed.&#x20;

Start monitoring the log file before you perform an action to see your changes take effect. In this case, we'll monitor a Discard, which will show all our recipients marked as SUPP for suppressed in the velvet log file.&#x20;

{% hint style="danger" %}
**You must click Resume when a Discard is complete or your mail queue will stay in a Discard state, permanently suppressing all newly injected mail.**&#x20;
{% endhint %}

{% hint style="info" %}
**Bypass Deferral**

If an IP address is waiting for an extended timeout period that was triggered by a deferral with a mailbox provider such as Yahoo and you want to test if the deferral condition has expired already, you can select bypass deferral to initiate an immediate delivery retry.&#x20;
