Can I automatically generate a contact list from my emails?

Question

I've been using Mail for years. But not Address Book.
I've got about 10,000 emails, and I'm wondering if there's a way to pull all the email addresses from Mail and automatically generate an Address Book out of it?
Or is there a utility somewhere?
Thanks in advance!

Answer 1

Yes there is.
There is a collection of AppleScripts called Mail Scripts available at this link.
http://homepage.mac.com/aamann/Mail_Scripts.html
The script you want to use from the collection of scripts is called Add Addresses.
+*Add Addresses*+
+Select all messages you want to use for creating the mailing list (for creating a mailing list, you would choose all messages in a mailbox which contains all messages on a certain topic).+
+Run the script and you get a list with all addresses contained in the selected messages - mark all the addresses you want to add to the Address Book using the checkboxes.+
+From the popup menu, choose which group you want to update with the selected addresses or select "Create new Group..." and enter the name for the new group to be created.+
+The script checks whether an address is already present before adding it to the Address Book in order to avoid duplicate entries. If additional information is available for an entry already present in the Address Book (e.g., full name information for an entry which had prior been email-only), the entry will be updated.+
