I am back six hours later and still the same problem. Earlier while I was here one of the Internet cafe's staff sent me an email using yahoo mail. I received it. When I tried to send a reply to her I received the same message. It seems everyone else can send emails from the Internet cafe. Only those using pprune email are blocked. This to me indicates that the problem must be at PPRune's server or ISP! How can it be here when everyone except pprune users can send email from here???
Pprune administrators - help and advice please! Thanks.
