This post assume that you already have Mutt running on your Mac OS X.

I choose Abook to manage my address book because it's very simple and suitable for my need.

If you don't have Abook yet, you can install it. I'm using MacPorts, so just execute this command:

$ sudo port install abook

And then, add these lines to your .muttrc config file:

set query_command = "abook --mutt-query '%s'"macro generic,index,pager \ca "<shell-escape>abook<return>" "launch abook"macro index,pager A "<pipe-message>abook --add-email<return>" "add the sender address to abook" 

A little explanation for above script:
1. set query_command (pressing ctrl-t) on Mutt - Compose view, will execute abook to look for match address based on the few letter(s) you already type in.
2. pressing ctrl-a on Mutt, will execute abook to input manually
3. pressing shift-a (or A capital) on Mutt - Index view, will add the sender from any highlight email

Just save your .muttrc and reload the config on Mutt, and you're good to go :)

On this past few weeks, I've been back using mutt. And this time, with much advanced configuration. One of its configuration is opening URL inside emails on your favorite browser. The requirement is simply using urlview that you can download from here (I'm using version 0.9), extract and compile it. Then add this config to your .muttrc file:

macro index \cu |urlview\n      # simulate the old browse-url function                                                                                                           

macro pager \cu |urlview\n

Also, you need to add ~/.urlview and put this line:

REGEXP (((http|https|ftp|gopher)|mailto)[.:][^ >"\t]*|www\.[-a-z0-9.]+)[^ .,;\t>">\):]

COMMAND <your-browser> %s

After all done, try to open one email in your mutt. Then in view mode, press ctrl-u and urlview will listing all available URL inside that email. You just have to choose one and press Enter, and your browser will automatically open and load that URL.
