Looking to extract all domain names containing EA, EB, EC, all the way to EZ (case sensitive). List has over 1k domains, sometimes much more.

Short Example:

List of all domains

EveryTime.com
EContest.com
EasyBuilder.com
EagleTech.com
EPlaylist.com
EEvents.com
EmeraldStore.com

What I need:

EContest.com
EPlaylist.com
EEvents.com

---

Now it wasn't hard to figure out a very slow way to do this - I am just in need of a faster way since I have to do it often.

If anyone knows how to do something like this any help is highly appreciated!
