Finding out e-mails addresses

Question

I am closing down an e-mail address because of too much spam. I wanted to send a "mass" e-mail to all the e-mail addresses in the sent folder (after editing them) to give my new e-mail address. Is there a way to get these addresses without doing it manually (since I don't have all e-mails on my address book)?
Thanks!

There are several steps involved, and you will need the Numbers application from iLife or Excel; otherwise you'll have to do the hard part by hand, which could take awhile and is tedious.
1. Select all the Sent messages and Save As… Raw Message Source; name the file "sentfile" (without the quotes) and save it to your Desktop.
2. In Terminal, type cd ~/Desktop and press Return.
3. Copy/paste this command in Terminal and press Return:
grep '^From ' sentfile | awk '{ print $2 }' | sort | uniq > sent-messages
Then copy/paste this command and press Return:
grep '@' sent-messages > complete-list
Next, add the .txt extension to the last file and open the "complete-list.txt" file using Numbers or Excel. Then Save As… or Export (depending on the options for the program you have) the file as a CSV file.
Then open that "complete-list.csv file in Numbers or Excel, Select All the items in the list and Copy them; open a new message window in Mail and Paste the list into the BCC field, which should all be separated by commas, and put your own address in the To: field. Type your message and Send it.
If you have neither of these programs or even a trial of Office:Mac, you should download the Office:Mac trial if you can, or you'll have to open the "complete-list.txt file in TextEdit, remove the carriage returns manually and then add commas between each email address and Save it, then copy/paste those entries into the BCC field in Mail.
