Hi All,
I'm having difficulty setting up sendmail in an FC2 network. The mail server is at 192.168.1.63 (on its LAN NIC) and all the other LAN machines are at 192.168.1.32-45. All the LAN machines can open the sendmail port on the mail server at 192.168.1.63:25, either by name or IP address. However, outgoing mail is only accepted from one machine: 192.168.1.32 All the other machines get 550 4.7.1 <email-address)... Relaying denied.
The same sendmail.mc and therefore sendmail.cf is being used on the mail server for the whole LAN, and does all the domain masquerading - so if it works for 192.168.1.32, why doesn't it work for 192.168.1.34 and the other LAN machines ? All the LAN machines are declared in the /etc/hosts file on the mail server and the HELO and server response is always correctly identified.
You can enable relaying for 192.168.1.* by adding the following line to /etc/mail/access:
192.168.1 RELAY
If you want to restrict relaying to just 192.168.1.32-45 then you'll need to list each IP individually:
192.168.1.32 RELAY 192.168.1.33 RELAY 192.168.1.34 RELAY .. 192.168.1.45 RELAY
Then, in directory /etc/mail, run:
make
Your LAN clients should then be able to relay mail through your mail server.
Paul.
