Normal email works fine.  If I try to attach a file to an email I get this message and the email does not go. "The host 'SMTP' could not be found. Please verify that you have entered the server name correctly"  (I have)  "Subject "name of my file" Account:POP3 Server SMTP, Protocol SMTP, Port 25, Secure (SSL): No, Socket Error:11001, Error Number: 0x800 CCCOD

This just started???
