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.
192.168.69.0/24 should be the proper setting here. 192.168.69.19/30 is
not a proper network. Are you absolutely sure that you did every step
in the howto?
I used mail to send a test message and it worked fine ( after I read
the man page -- I haven't used mail to send a message for 20 years or
more!).
There must be other errors in your postfix config.
When you start postfix, does it throw any errors in the logs?
The 192.168.69.19/30 was just a test after 192.168.0.0/24 and
192.168.19.0/24 both failed (i.e. I could send an internal email). To
make clearer this is what I have in my main.cf file
mynetworks = 192.168.69.0/24, 127.0.0.0/8
Starting Postfix does not throw any errors.
I can download emails using POP3 with postfix and davecot, can't I? I
don't have to use IMAP, right?
