From time to time your mail queue may get filled up. This may be due to network problems or misconfiguration. For instance, if you botch (typo) the relayhost parameter, the mail will be undeliverable.
+
 
+
The first thing to do is fix the problem, meaning get the network back online, or fix the configuration. Issuing this command will tell postfix to try and deliver the mail from the queue.
+
 
+
  postfix flush
+
 
+
However if you discover (using the ''mailq'' command) that the deferred mail is useless anyway, it may be desirable to just purge it from the queue without delivering, like so...
+
 
+
  postsuper -d ALL deferred
+
 
+
Finally, specific messages can be removed based on their message ID, which is the first thing shown for each message shown in the ''mailq'' output.

Welcome!

Welcome to the Secure Computing Networks wiki. Our goal is to produce a resource for Unix, Mac, and Windows System Administrators with information on configuration, trouble-shooting, and utilities for easier use and management of their systems and networks.

I will be attending BSDCan this year! If you'd like to meet up, drop me an email.

Background

The SCN Wiki got started as a personal project of mine, to store all the various configuration and trouble-shooting data I acquire in my job as a FreeBSD Administrator, and as an ad-hoc developer. Over time, I started doing more complete write-ups for things such as OpenVPN and OpenLDAP. Today, I get a modest 4,000 hits per day to these complete articles.
