I have Win 7 livemail linking to my Blueyonder/virgin account.
When I type new email and hit its "send" button , nothing happens. If I choose option to send later , it goes into outbox as expected, and goes OK when i hit send/rcv on toolbar. incoming mail works OK... pop/smpt config set up OK I guess as it does communicate with virgin/blueyonder. I raised it on the Win7 forum
