Problem:

Setup a post view, filter the results by post title's first letter.

Solution:

There isn't such kind built-in feature within Views plugin, as a workaround, you can try these:

1) Create a custom taxonomy "alphabetic",

2) Edit each post, setup term a,b,c ... z in above taxonomy "alphabetic"

3) So you will be able to add taxonomy "alphabetic" filters into the Views search form.
