It's news to me that it even looks for a dial tone, Lona, but that doesn't mean to say it doesn't. If I were you, I might, however, just be inclined to check that I haven't inherited a rogue dialler from somewhere. Check your Network Connections folder, to make sure it's just Pipex in there, then check IE Tools > Internet Options > Connections, to make sure it's dialling Pipex. The only other thing I can think of to check is that your e-mail client isn't disconnecting after sending / receiving.
