(You might notice that this is a slightly-modified repost of previous content. It was necessary to deal with Blogger suddenly taking issue with a post containing a giant list of domains.

Click here to download the full “MAGY” (Microsoft, AOL, Gmail, Yahoo) domain list, and feel free to use it for email segmentation. (And please don’t use it for spammy purposes.)
