First of all make sure you have the correct information in your SMTP settings (page "Administration" - "Settings" - "Notifications" - section "E-Mail sending settings").

Then check if you have McAfee VirusScan or any other Antivirus/Firewall software installed on your computer. These applications might block TCP port 25. Unblock this port in firewall/antivirus settings.
