I have built an jsp - based eMail client! For instance I can read and write mails with it. It works for all providers. Only at the provider T-online it givs an problem by reading mails: "javax.mail.MessagingException: Connect failed; nested exception is: java.net.ConnectException: Connection refused" --> this is the error message
Can any one of us help me?

thx + Greetings
