Connections to the server “imap.virginmedia.com” on the default ports timed out.
I've been having exactly the same problem for a couple of weeks now. It's driving me mad. Nothing has changed at my end so it must be VM. When I contacted them last week they admitted there was a problem with email which they were working on. They must have changed something because it's been fine for years! I'm getting really fed up with it!
