1 Introduction
When you manage Postfix and have a trouble with your mail infrastructure, you may want to set in maintenance your Postfix without stopping the service. Here is a way to hold the queue, giving the time to analyze the problem and then release the queue.
2 Usage
You need to configure your Postfix as follow:
 /etc/postfix/main.cf
|
defer_transports = hold default_transport = hold |
Then restart Postfix. Once you're ready and want to release the queue, remove those two previous lines, restart Postfix and force the queue to release:
|
service postfix restart mailq -q |
You can then look at the current status of deferred mails:
| qshape
|
> qshape deferred
