Help understanding how mail server should be setup

[micko_escalade]

Hi all!

I spent couple of hours reading thru whole forum trying to figure out what are steps to get it running, but no joy,
I have VPS (virtual private server) with Fedora 4 installed on it, I installed webmin, apache2, mysql, php and they're working fine,
now Dovecot IMAP/POP3 Server is giving me headache,
can someone give me a list of required modules to get mail working.

Thanks!

Have a look at this tutorial: http://www.howtoforge.com/perfect_setup_fedora_core_4

In the tutorial I install the package imap; leave it out as you have installed Dovecot. You should then add these steps after the Postfix configuration because Dovecot uses Maildir:

postconf -e 'home_mailbox = Maildir/'
postconf -e 'mailbox_command ='
/etc/init.d/postfix restart

If you want to install ISPConfig afterwards, you can create your mailboxes with the ISPConfig web interface; if you want to create your mailboxes manually, have a look here: http://www.howtoforge.com/forums/showthread.php?t=2

Thanks for the reply falko!

so in putty I should run this code bellow ?

postconf -e 'home_mailbox = Maildir/'
postconf -e 'mailbox_command ='
/etc/init.d/postfix restart

and since my VPS has only 128MB of ram I think I shouldn't install ISPConfig,
or I can install it but not run on a boot ?

Yes.

It depends on how much RAM is eaten up by your other applications.
You can install it and then remove the system startup links so that it doesn't get started at boot time.

I run the code and everrything went ok, with no errors,

but when I send test email from yahoo.com to my VPS it newer gets there,
outlook shows this error screenshot when I try to send email from outlook
www.dnsstuff.com gives this error link
also www.dnsreport.com at the buttom gives gives error for MX record link

I have 3 virtual domains, maybe that's causing problems?

Is 207.210.228.31 your server's IP address, or does it belong to another server?
Is your server connected directly to the internet, or is it behind a router?

[micko_escalade]

That ip is my VPS (virtual private server) ip, which is located somewhere in the US, and from what I've read looks like the problem is with Reverse DNS not set up for that ip.

That is likely. You can ask your ISP/hoster to set up a reverse record for that IP address.

Ok, I asked my provider and they set reverse dns, but still can't get it to work,

It might take up to 72 hours until the changes propagate.

You seem to have Sendmail installed. The things I posted above are for Postfix... Now which Mail server is really installed on your system?

Also, please post the output of

netstat -tap
