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?
Dovecot is the server that provides POP3 and IMAP to the users.
Postfix is the server that moves mail from place to place.
so you logged in as federica and sent an email to giulio. Did you then
log in as giulio and try to read the mail?
I did
I haven't used mail in so long I am not sure if it works with maildir.
I think it reads from /var/spool/mail or /var/mail directly, but you
have set postfix to deliver to Maildir stores. You can also install
squirrelmail on the server and apache, and then just log in to
http://yourserver/webmail and read mail that way. But you would also
have to make sure dovecot is set up.
Actually both, as /etc/mail is a symlink to /etc/spool/mail. I wasn't
expecting to find my email there but I did expect to be able to use
Thunderbird to download my emails. So maybe there is something wrong
with Dovecot....
Have you thought of just using something like SME server (based on
CentOS 4) as your server?
It does most of the work for you, and has a very user friendly admin
system through web pages.
Ok, so maybe I've take the wrong path. This is what I am trying to achieve.
I want a mail server, obviously, with the ability to use both POP3 and
IMAP. I usually download my emails on my laptop (and the other users,
like federica, on their PCs), but I want also to be able to install a
webmail (most likely squirrelmail). Finally I want to install majordomo
to manage some MLs.
What do you suggest then?
