My b2evolution Version: 2.x

I have a blog from b2evolution uploaded to http://blog.ghanatrot.be/blogs
To make it possible to publish blogposts by e-mail I had to create
a new e-mail account where the blog searches for new posts.

In my b2evolution account they ask for:

- Email method: POP3 or IMAP
Here I choosed POP3

- Email server or IP of entering email:
Here I choosed 'mx.000webhost.com'

- Port number:
Here I choosed 110

- Account identifier and password for email server
Here I filled in my login and password for the email account
I created in my blog hosting on 000webhost.

- ID of categorie
some initials

- Prefix of subject:
ID + '_'

The function of publishing blogposts by email doesn't get activated and
I don't know why. Please if someone has an idea ... ?
Thanks.
