    Hi to all members, first I want to thank for all the information you expose in the forum for users like me in relation to linux and ispconfig.
    I have to say that after many hours of work, I hang on the following issue.

    I install Ispconfig on a ubuntu 10.10. The installation was as the perfect guide explain.I can send emails without any problem but I can not receive email messages from external servers.

    I have open ports 110 and 995: see netstat txt

    I can internally send and receive mail.
    Attached is the mail log of an intent of receive a email sent from a mail [email protected] from external domain to [email protected] which is the one domain where ispconfig is the ruler.

    Please help me.

    MX record for latinluz.com points to mail.latinluz.com, but there is no A record for mail.latinluz.com. Please correct your DNS enties.

    Moreover, you need to open port 25 also for smtp connections to your server from external mail server.

    Hope this helps.

    Thank for your replay dear Dipesh.

    I follow the guide How to Run Your Own Name Server With ISPConfig 3 And Fast Hosts.

    Port 25 and 587 are open for smtp and working fine. This is the ispconfig DSN setting on server.

    DNS zone set up:
    A latinluz.com. 68.209.97.120 0
    A mail 68.209.97.120 0
    A ns1 68.209.97.120 0
    A ns2 68.209.67.120 0
    A www 68.209.97.120 0
    MX latinluz.com mail.latinluz.com 10
    NS latinluz.com. ns1.latinluz.com. 0
    NS latinluz.com. ns2.latinluz.com. 0

    Do I have to add another A record ?

    I am not expert in DNS configuration, but I surely doubt that the resolution to your problem depends upon DNS config.

    Thank very much dipesh, I added the record, your clue about mxtoolbox show that the record was empty, I entered the IP in a @ mail record on the provider site. Now when I sent a email, the email is traying to reach the email server but is not going to the mailbox of latinluz.com, specifically to dalaniz user. How can I debug this ?
