no email notifications from profilux

[BigAl07]

Mine works fine, settings:
smtp.mail.yahoo.com
port: 25

The weird thing is, it will only email to my yahoo account and not to other emails.

Above your password, don't put @yahoo.com - just put your username.

I tried those settings and still didn't get anything (even to my own yahoo account). Is there a way to run a "Test" and be able to "See" where it's failing?
