Everything worked until last week, when I had some suspicious emails, supposedly from Amazon, saying someone in malaysia was trying to hack my account.
So, just to be safe, I updated my email password (I'm a legacy customer using ntl) and since then it has stopped working. Sending works, but receiving doesn't, the error message says it can't log in to the server (pop.ntlworld.com) because authentication failed. I've tried to get a VM error number but haven't managed so far.
