If it is not one thing, it is another. I recently had to set up a web server using Mac OS X 10.4 that needed PHP 5 and Postfix so I could send email via a particular PHP script. I used Marc Liyanage ‘s PHP 5 package and then decided to to then use Mac OS X’s built install of Postfix to handle the mail. After having some issues getting Postfix working, I finally found a great article on http://www.macosxhints.com which helped with my mail and launchd questions – as I have never had to do anything with launchd up until this point. (Goodbye cron, hello launchd)
At this point I was pretty proud of myself and figured I got Postfix working because of my pizza combos intake, but then a few minutes later and a ton of email messages later, I realized all my failed attempts and test messages had built up in the que. I now had to scramble to unplug the server and figure out how to manage the Postfix queue…something I had never done before. Enter my quick tips for managing the Postfix queue:
- To view the queue, use:
mailq - To delete a message, use:
postsuper -d 111(111= the message ID found by runningmailq) - If you want to delete all messages in the queue, use:
postsuper -d ALL
One problem solved, 24 more to go
