My b2evolution Version: 3.3.1 Los Angeles

HI everybody:

I have installed version 3.3.1 and I have activated the "email subscription" in severa blogs and it works OK, however I have realised that the system is using the e-mail of the blogger to comunicate the new entries, allthough I have configured an email in the variable notify_from in the _advanced.php file.

Should I change any futher configuration?.
