Prerequisites
OS X with Mail and cron installed
Information
This is a little script I wrote out of necessity to disabled my work email account after work hours and at weekends. I use cron with the following info to run the task every half an hour mon-fri.
0,30 * * * 1-5 /usr/bin/osascript /Library/Scripts/Custom/workemail.scpt
osascript is neccessary as cron can't call an applescript directly
To customise replace Dev etc with the name of the email account you wish to be the subject.
Recognition
I pulled snippets of information and code from various sources, some pretty obscure. If you recognise your work and want a mention please send me a message.
