Removing Messages from Queue
In case of an email address typos or network connection issues, the emails need to be removed manually from the Queue. In this case, the Remove Messages button can be used. It contains 3 available options for Removing only selected messages, Removing all messages, or Removing messages that match certain search criteria.

Afterward, the verification message will appear with the count number of removed messages.
The sender will receive the following postmaster message about "Message was manually deleted from the queue".

Go to Status > Message Queue > Message Queue Processing to view the status of messages that are currently being processed.
