I have just installed CentOS 5.1 on my home server and I am trying to
set a mail server.
I have diligently followed the instructions on the Wiki - How To on the
CentOS website (http://wiki.centos.org/HowTos/postfix). However I cannot
send internal email (I haven't yet tried externally).
Do you have any suggestions on what to check? To test it I used two
normail user: giulio and federica. I logged in as federica and sent an
email to giulio with the mail programme. Is this correct (i.e. using the
mail programme)?
There is one thing that I don't quite understand from the instructions.
In section 3.1 it's suggested to set
mynetworks = 192.168.0.0/24, 127.0.0.0/8
in the /etc/postfix/main.cf file. My home network however is
192.168.69.0 and actually the IP assigned to any computers in the
networks start from 192.168.69.20. So I changed mynetworks to
192.168.69.0/24 and also 192.168.69.19/30 (as my server IP address is
actully 192.168.69.25). I don't think this is the cause of my problem
anyway, because it didn't work even with the value suggested by the Wiki
page.
Thanks for you help
Giulio
