I am trying to set up my fedora core 2 server, with postfix running as the MTA, to restrict access to my internal email distribution lists. My distribution list is very simple at this point. I have one alias in aliases.db that maps to 2 local users. when i add these commands to main.cf, postfix starts, this is what I get when i telnet to localhost 25: [root@dev1 postfix]# telnet localhost 25 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. It should be [root@dev1 postfix]# telnet localhost 25 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. 220 dev1.maniatv.com ESMTP Postfix Any idea what i am doing wrong? I followed these instructions: (http://www.postfix.org/RESTRICTION_CLASS_README.html) /etc/postfix/main.cf: smtpd_recipient_restrictions = hash:/etc/postfix/protected_destinations ...the usual stuff... smtpd_restriction_classes = insiders_only insiders_only = check_sender_access hash:/etc/postfix/insiders, reject /etc/postfix/protected_destinations: all@xxxxxxxxx insiders_only all@xxxxxxxxxxx insiders_only /etc/postfix/insiders: my.domain OK matches my.domain and subdomains another.domain OK matches another.domain and subdomains Thank you, Ryan Swift Below is my postconf -n...
