Thanks for replying to my problem. I'm using Window Mail not Outlook Express. I did as you suggested and checked "This server requires a secure connection" for both boxes for Outgoing (SMTP) and Incoming (POP3). I then tried again to send the message. It did not work. I got the following error.
"Subject 'Two pictures of Your Mum and I', Account: 'pop-server.satx.rr.com', Server: 'smtp-server.satx.rr.com', Protocol: SMTP, Server Response: '250 8BITMIME', Port: 25, Secure(SSL): Yes, Server Error: 250, Error Number: 0x800CCC7D.
The connection to the server has failed. Account: 'pop-server.satx.rr.com', Server: 'pop-server.satx.rr.com', Protocol: POP3, Port: 995, Secure(SSL): Yes, Socket Error: 10060, Error Number: 0x800CCC0E."
So now I have a different problem. Before doing as you suggested I clicked on the Server tab and checked the box "My Server requires authentication." Maybe that was the wrong thing to do. Thanks a gain for your help.
