e-mail settings for local use of Plone 3.0.1 on MacOS 10.4.10

Hello,

I'm absolutely Newbie in Plone. I would like to make the first steps local on 
my PowerBook. The installation is ok. With the admin I can enter and explore 
all the features.

But I would like to learn handling the content not as admin but as user with 
different rights. So I tried to create a new user but I can't finish the 
sign-on process. I get the error-message:
Failed to create your account: we were unable to send your password to your 
email address: (61, 'Connection refused'). I'm not familiar with setup 
mailservers and similar things.

I think my e-mail settings are wrong. I am very happy, if someone can tell me 
the values I have to set for
- Mail server: SMTP server, SMTP port (ESMTP username and password I think they 
will remain empty)
- Mail sender : Site 'From' name and Site 'From' addres.

Thanks in advance
Gilberto Zappatini
