    Is it allowed that I use "yum update" to update complete system?

    Why ISPConfig won't accept new data for Server settings?

    Management --> Server --> Settings ISP Server

    Servername, Hostname, Domain, IP ...?

    Have you installed the mySQL database dump for ISPConfig manually?

    During the re-installation, if ISPConfig installation fails, sometimes is happening that new reinstall fails because ISP can't connect to database using:

    user=root pass=none

    ?

    (And during perfect setup, pass was set)

    Is it necessery to delete users & groups (unix) created by ISPConfig, if someone want's to re-install ISPConfig?

    Would be good, though it's not necessary.:)

    Is it allowed to install Webmin too?

    Does it interfere with ISPConfig?

    Is it allowed to use Yum?

    Does it interfere with apt-get?

    yes. But be careful.

    yes. But do not use it to configure services that are already configured by ISPConfig like apache, bind, postfix, system users, ftp.

    Yes.

    No, you can use yum and apt together.

    OK,

    I re-installed OS once again, step by step
    I reinstalled ISPConfig once again, step by step.

    I can send email, but I can't receive any emails.
    It seems just like emails are not reaching postfix, or they are saved nowhere?

    (I didn't installed webmin this time, neither updated system using yum)

    Ok, then tell me the email address you tried to send to, and also tell me your public IP address.

    Ok, dig shows the correct information.
    Do you forward port 25 from your router to your server?
    Do you see anything in the mail log in /var/log?

    I dont know anything about forwarding because I am not network administrator.
    My ISP told me that all ports are opened and mapped through NAT1:1

    Yes there is log info in /var/log

    Yhere is log about sending emails, but no about receiving of emails

    Getting MX record for noc.homelinux.com (from local DNS server, may be cached)... Got it!

    Host Preference IP(s) [Country]
    noc.homelinux.com. 10 87.116.140.158 [CS]

    Step 1: Try connecting to the following mailserver:
    noc.homelinux.com. - 87.116.140.158

    Step 2: If still unsuccessful, queue the E-mail for later delivery.

    Trying to connect to all mailservers:

    noc.homelinux.com. - 87.116.140.158 [Successful connect: Got a good response [250 Ok]]

    Your router (I assume you're in a home network) should have a web interface where you can configure port forwarding. Please forward port 25 from your router to your server.

    No, I am on cable network.
    Network administrator told me 1o minutes ago that all ports from private network (10.40..) are forwarded to public IP.

    BTW why we are talking about port 25?

    Isn't a problem in port 110?

    I can send emails, but I can't receive them

    Any meaning in this:

    10.40.250.236 is another PC in my private home network (there are 3 of them, server is on 10.40.239.218

    Because if someone sends you an email, it will be sent on port 25.
