Kathleen.
Thank you for your reply.
In the end it was changing SMTP from 25 to 587.
BT have said that there is a temporary problem with there server and Vista,
port 25 at present is not working and as a temporary mesure they are using
port 587 until port 25 is fixed which they expect to be in a few weeks.
They say that port 25 is the main port for the server, and to keep trying to
change back over the next few weeks, as 587 is really not the correct port if
you know what i mean.
I imagine this subject will come up again when the correct server is back on
line.
Again many thanks for your advice
Cheers
