"So I changed mynetworks to 192.168.69.0/24 and also 192.168.69.19/30"
192.168.69.19/30 should not be in there. What exactly does it say?
This?: mynetworks = 192.168.69.0/24, 192.168.69.19/30 should be mynetworks = 192.168.69.0/24, 127.0.0.0/8
(the /24 assumes you are using 255.255.255.0 as your subnet mask, and then tells postfix to trust mail from machines in the 192.168.69.0-255 range)
Looks like you are trying to tell it that your clients start at .20, but that's not something its going to need to know or understand, and is not a legitimate entry anyway. I would think it could be the cause of your problem, if you are logged onto the server (localhost) and using mail to send messages. You've removed the 127.0.0.0/8, which (I don't use postfix, so I could be wrong) would remove localhost from the trusted addresses,

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 _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
