Ever had some alerting software spam your production mail queue with 1000’s of alerts?
And you dont want to delete every message individually…

Here is the solution to delete all messages destined for user@example.com:

mailq | tail -n +2 | grep -v '^ *(' | 
gawk 'BEGIN {RS = ""} /user@example.com/ {print $1}' | 
tr -d '*!' | postsuper -d - 

Thanks to http://www.keithscode.com for that one!

echo “YAY HTML Works” | mail -s “$(echo -e “Subject Goes HerenContent-Type: text/html”)” to@yourmum.com

I recently moved my website to a cheap VPS I had the fun journey of trying to get it work without grinding to a halt everytime I clicked on a page, which you ‘should’ have noticed is fixed.

Firstly I needed to be realistic this blog wouldn’t have more than two simultanious connections at once, with that known I could then edit the amount for apache server threads to an un-godly small number in /etc/apache2/apache2.conf

StartServers 2
MinSpareServers 2
MaxSpareServers 2
MaxClients 20
MaxRequestsPerChild 0

With that noted a quick look at ‘top’ shows MySQL eating lots of Virtual Memory a quick swap of the configuration file: /usr/share/doc/mysql-server-5.1/examples/my-small.cnf to /etc/mysql/my.cnf sorts out that problem. (Don’t forget to backup your originals)

And finally modifying the WordPress max memory limit as noted in this post
