Hello, I have just installed Postfix mailerdeamon, and now I am unable to send email out of the network. After searching, I discovered that I am also unable to telnet to the smtp port of the delivery-mailserver. That is: $ telnet mail.somewhere.nl 25 Trying 194.... and then it hangs. It is with every mailserver I tried. Other ports work correct. What is going on? Has it something to do with my Postfix configuration? Thanks, Sebastiaan
