Find a page where a lot of people have posted their email ids in comments or posts.
For example: http://www.oyindia.in/forum/thread-8716.html
You can also checkout the mafia wars add pages on fb or orkut community forums about recharge codes and scams.
To know how many email ids are there on the page just click find (Ctr+F) and input @ you will see the number of email ids (I'm using Google Chrome browser)
Now select all the text (Ctrl+A) on the page and copy it (Ctrl+C)
Open this link http://eel.surf7.net.my/ and on the input window paste the content you copied (Ctrl+V), click extract and wait a few seconds.
After a while on the output window you will get the extracted email ids. Copy paste that into notepad or excel and save. Go to more pages and do the same and build a list.
