[Dovecot] I wrote CheckPassword Shell example for Dovecot

[Nicolay Vizovitin]

Hello,

Seeing as there are not too many Dovecot CheckPassword driver usage
examples on the Internet, I wrote one using Shell script.

You can see post about it here:
http://devblog.plesk.com/2013/11/shell-checkpassword-authentication-in-dovecot/.
The post also has a link to Mercurial repository with the example.

Feel free to use the example as you see fit. You may even include it into
documentation (or link to it), if you'd like.

Thanks for such great software as Dovecot!
