Recently set up a Ubuntu LTS 12.04 box to act as a web and mail server.
I'm having some difficulty figuring out what to set in the Postfix configuration for the "Local Networks" setting using:
- I have 5 static IP Addresses from my provider. xxxx.xxx.xxx.25 thru xxx.xxx.xxx.30Code:sudo dpkg-reconfigure postfix
- The mail server FQDN is set to mail.xxxxxxx.com and the IP address is xxx.xxx.xxx.25
- under the Local Networks setting, I have the default of 127.0.0.0/8 and then I'm not sure what to use next for the ??? portion of xxx.xxx.xxx.25/???
Ideally, i would like it to just cover that single ip address. Should I then use xxx.xxx.xxx.25/32 ?
Thanks in advance
