Currently see this:
The connection to the server has failed. Account: 'Walker', Server: 'smtp.idnet.com', Protocol: SMTP, Port: 25, Secure(SSL): No, Socket Error: 10060, Error Number: 0x800CCC0E
Even webmail fails!
Doesn't seem to be any problem here, Andrew.
Thanks Simon, the dentist analogy has just kicked in!! Remarkably, it's recovered but neither PC in this house could send anything :)
