Mac OS X Lion Mail.app has a ton of new features and not the least of them is the conversation view that makes it look much in like Gmail.
Still, unlike Gmail, Mail.app by default shows only incoming conversation and omits sent messages, unless one presses the “Show related messages” button.
Fortunately there is a preference option to turn this on constantly.
Go to menu “Mail > Preferences > View” and check “Include related messages” box.
I wonder why this option is turned off by default?
Some time ago I found a rather useful way to use my Address Book contacts – group them and when you type the name of the group in Mail.app address field, it is expanded to all the contacts. But the problem was that when a contact had multiple addersses, I could not determine which was to be used for the group automatically and if I wanted to write to a specific address I had to manually adjust, which I forgot rather often.
Edit Distribution List
Fortunately Address Book has a way to specify the default address for any group (or distribution list as it is called). Just right-click on one of the groups, as shown below and pick “Edit Distribution List…”
Pick Edit Distribution List from options
Now a window pops up that shows you the entire list and all of the multiple addresses for each card. Just skim through the list and highlight in bold the default addresses which should be used automatically for this list:
Clik OK to save changes and your done.
