This is just a short little blog on getting ‘mutt’ going with GPG support on a Mac OS X machine. Started off with me having issues getting to my mail at customer sites and the over all lack of a good PGP option on my iPhone.
This seemed like a simple option. (Mostly this post is so I can recall how I set things up for the next time I need to do it in the .muttrc file)
The first thing your going to want / need is Xcode on your Mac so you have GCC -
*this is free in the App Store*
After that d/l and install Mac ports:
http://www.macports.org/
then run the following command
sudo port install mutt-devel +imap +ssl +headercache +gnupg +smtp +sasl +trash
Now you will need to build a .muttrc file for your home dir; mine looks like this, you will need to edit username, hostname, and the PGP key 0x00000000.

Note that you will also need to setup gpg to work with your keys or make keys.
At this point you are good to go, just run ‘mutt’ from the command-line and your rockin.

Can you install Mutt with Homebrew? Homebrew is a lot easier to work with than MacPorts imo.
