Am using tiscali smtp / pop3 settings to recieve / send e mail through outlook. All are 100% as tiscali state they should be. But Outlook will not send any mail ... could it have anything to do with Norton 2007 settings ? Or anything else ?
Sounds like a firewall issue. Try disabling norton (you should be able to do this by right-clicking on its icon at the bottom-right of your screen), and then see if it works.
