    I can send mails,. but I cannot recieve, when I try to send from T-bird it pop`ups - something about bad MX entries, but when I send emails from e.g. Gmail, it returns message saying...

    "This is an automatically generated Delivery Status Notification

    THIS IS A WARNING MESSAGE ONLY.

    YOU DO NOT NEED TO RESEND YOUR MESSAGE.

    Delivery to the following recipient has been delayed:

    Do you use the DNS server from your provider as DNS server or do you use your ISPConfig server?

    Did you open port 53 (TCP and UDP!) in your firewall? Is BIND running?

    same problem

    Hi, I have the same problem.

    The strange thing is that it has been running for about one year with no problem but a few days ago it stops.

    I use ISPConfig as DNS server and port 53 is open (TCP and UDP)

    Ispconfig version is: 2.2.35

    SMTP-Server:Online
    POP3-Server:Online
    BIND-Server:Online

    The /var/log/mail.log file does not show anything about incoming email from gmail.

    Thanks if any recomendation

    Please check if your MX record points to the correct server.

    Yes it does.

    In MX record, I leave the hostname blank, priority: 10, Mailserver: XX.XX.XX.XXX where XX.XX.XX.XXX is my server IP.

    Take into account it used to work fine for one year.

    A few weeks ago I unabled spamfilter, antivirus and URIBL for a few emails account but it goes on working perfectly after this.

    Thanks.

    emails from others providers finally enter (one email arrived about 20H late but it arrived).

    It seems it only fails for incoming emails from gmail with the message error emailed to the sender:

    Technical details of temporary failure:
    DNS Error: Could not contact DNS servers

    From the server to gmail, it works fine.

    What can this be due to ???

    Your MX record must point to an A record which then points to an IP. An MX record must not point to an IP directly.

    Hi,

    I pointed MX record to mail.myweb.com and created A record mail.myweb.com pointing to my IP. It does not work.

    ISPconfig shows:

    I cannot find out what I doing wrong. Thankyou very much for your help, sorry for my unknowledge.

    I think I got it.

    It seems it was a DNS misconfiguration.

    I created the ns1 and ns2 Arecord and all seems to work fine now.

    Thankyou very much Falko.
