Here is my situation. I am a recovering Windows administrator, and except for one exchange server, I have been Windows NT4 Server and Windows 2000 Server free for six months. Well, I am in my last phase of recovery, and am trying to break my addiction to Exchange by creating a Mandrake Linux server with Postfix to handle the email. Once I get the new email server working I can down Windows NT 4 for the last time. So, the good news is that everyone on the LAN can use MS Outlook 2000 to send emails to, and receive emails from everyone else on the LAN. Furthermore, everyone on the LAN can use MS Outlook 2000 to receive emails from clients, friends, and family, anyone from outside our LAN. The problem is that everyone on the LAN can not send emails to anyone outside our LAN; or perhaps better said is that no one from outside out LAN can receive emails from any of our users on the LAN. Below you will find a copy of the master.cf, and the main.cf files, as well as the text of messages we get four hours after we send a mail to the outside world. I don’t get any messages that tell me the address was undeliverable, or messages giving me any indication of why we cant get out mail to the outside world. A review of my /etc/xinet.d shows that I have imap, imaps, pop2, ipop3 and pop3s among others.
Please note that I have changes the name of the domain in the test below because I don’t want to be attacked by scriptkiddie who spotted a mistake I made in the configuration.
Any assistance will be greatly appreciated.
