I like to periodically change passwords on everything, especially on my personal email server. Changing passwords regularly keeps the bad guys, and the NSA guessing.
On my email server, the mail store is actually stored in an encrypted Truecrypt volume. Also, my email server is running on Linux so that means I have to do everything via a terminal.
So here is how I change that password:
With the Truecrypt volume dismounted run the following:
#truecrypt -C tc-volume.tcFollow the prompts to change your password! Simple right?!
Make sure you change the volume name above with your Truecrypt volume name.
