Email Campaign doesn't send email

[rnatavio]

Hello.

I have SugarCRMCE5.0.0c (i used the 'exe' windows installer), and MySQL Server5.0, and the latest version of PHP installed. I have configured my email settings properly based on my Mozilla Thunderbird SMTP settings but whenever I try to send email, i get prompted with:

Error emailing:The following From address failed: [myemail@goes.here]

I am able to receive emails but the problem is, i can't send outgoing mails. Which also mean that I can't get to try the Email Campaigns, and the Marketing side as a whole. Am i missing something?

btw, I'm using both Mozilla Firefox2.0.0.14 and MSIE6.

Have you set up a Inbound Mailbox in the Administration backend?
