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.

Mail Server Stuff

First off, the learning curve on postfix blows donkey balls. Secondly, I've been using sendmail for way too long and don't really WANT to use postfix. However, I admit that there are quite a few great advantages to the postfix MTA, such as Virtual Domains and the user interface.

Postfix How-To

How to clear the queue

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.

 postsuper -d 0C0FF240F2
