Since SSL only affects the outgoing mail, receiving mail shouldn't be a problem. Two questions/comments/suggestions.
Are you trying to set this up via a WiFi connection to a broadband link provided by NTL? This could be an issue if you're not because many service providers will not accept non-SSL outgoing mail because of a security risk - for 'vanilla' SMTP no account name or password is required and so it's possible to send emails purporting to come from someone else. It's called the 'port 25 relay problem' and so most service providers will only accept outgoing SMTP mail if the SSL option is used, unless you're sending from your 'home' broadband/WiFi network. Then the service provider can positively identify you. I have this problem too and so I use a hybrid account - I receive (using POP or IMAP) on my service provider's mail server but send using gmail, because Google supports SSL.
