Forced delivery and removal of messages from the queue
To forcedly send or remove messages from the queue of the MTA:
In the main window of the application web interface, open the management console tree and select the Message Queue section.
View the list of queued messages in the workspace.
To the left of the queue type name, select check boxes next to the messages that you want to process.
Click one of the following buttons on the toolbar in the upper part of the workspace:
Flush if you want to forcedly send the selected messages.
Flush All if you want to forcedly send all messages.
Frequent attempts to deliver undelivered messages out of turn affect the speed with which the other messages are sent.
Delete if you want to delete the selected messages.
Delete All if you want to delete all messages.
The operation of removing all messages from the queue permanently removes all data from the queue, including messages that have been received but not processed yet.
