TTL, you don't have to be :) Use WLM's simple way or use the recipe at <http://www.postfix.org/STANDARD_CONFIGURATION_README.html#null_client> (see below the sig for the relevant excerpt). Postfix isn't H E A V Y (quite the contrary); if you like, I can post ps auxw | grep -i sendmail and ps auxw | grep -i postfix so you can see for yourself what is H E A V Y and what is lite. Plus, you keep open the options to corral the folks on your LAN so you won't have to worry about getting off the top few lines at senderbase.org. rgds/ldv <http://www.postfix.org/STANDARD_CONFIGURATION_README.html#null_client> says in part: In this example we assume that the Internet domain name is "example.com" and that the machine is named "nullclient.example.com". As usual, the examples show only parameters that are not left at their default settings. 1 /etc/postfix/main.cf: 2 myorigin = $mydomain 3 relayhost = $mydomain 4 inet_interfaces = 127.0.0.1 5 local_transport = error:local delivery is disabled 6 7 /etc/postfix/master.cf: 8 Comment out the local delivery agent entry Translation: * Line 2: Send mail as "user at example.com" (instead of "user at nullclient.example.com"), so that nothing ever has a reason to send mail to "user at nullclient.example.com". * Line 3: Forward all mail to the mail server that is responsible for the "example.com" domain. This prevents mail from getting stuck on the null client if it is turned off while some remote destination is unreachable. * Line 4: Do not accept mail from the network. * Lines 5-8: Disable local mail delivery. All mail goes to the mail server as specified in line 3.
