Hi Bill,
More specifics:
The linux machine with the toaster installed is set up to be used as an smtp-relay for my LAN. All LAN computers IP adresses have been added to the tcp.smtp file. These LAN computers all have the linux machine set up as smtp server for their (outgoing) mail. So what the toaster machine should do is: accept an incoming smtp connection from all LAN computers (which it does), relay it to the correct server. This is where it goes wrong:
My ISP blocks all incoming ports < port 1024. Which means if you would try to telnet to my linux toaster machine from a non-lan computer 'telnet ip-of-linuxmachine-with-toaster 25' => this would be blocked by my ISP. So the problem is that when my toaster tries to relay the outgoing mail I eventually get the message:
"delivery 11: deferral: Sorry,_I_wasn't_able_to_establish_an_SMTP_connection._(#4.4.1)/"
So I believe a more technical explanation would be that when relaying my machine sends a request as client to an external mailserver, this server sends its response, but the respons doesn't reach my server because the response is sent to a port < 1024. Can this be solved in any way?
I hope this is more clear.
