Windows Firewall stopping sending mail via SMTP

windows-firewallwindows-server-2008

With Windows Firewall enabled (turned on) on Windows Server 2008 my 3rd party application (3ware RAID controller interface) can't send email notifications –
Basically, in the settings, i configure SMTP server, user, password etc…

When i turn off windows firewall, it can send it fine…

Which setting in Windows Firewall would be preventing this?

Add each application to the firewall's allowed list.
