mailq

Postfix to Sendmail compatibility interface

List the mail queue. Each entry shows the queue file ID, message size, arrival time, sender, and the recipients that still need to be delivered. If mail could not be delivered upon the last attempt, the reason for failure is shown. This mode of operation is implemented by executing the postqueue(1) command.

root@Webserver:~# mailq
-Queue ID- --Size-- ----Arrival Time---- -Sender/Recipient-------
6761B21C519      470 Sat Jul 15 14:56:33  www-data@Webserver.local
