    I installed a single ispconfig setup, with everything working correctly,
    Master Panel Is apache
    Slave Panel is NGINX
    I added a new slave server that has everything as well db, dns, roundcube,jailkit, except the interface
    Error 1
    Client that is set up on that server cannot visit for their email
    Error 2
    DNS servers responded ERROR: One or more of your nameservers did not respond:
    The ones that did not respond are: MAIN IP ADDRESS
    I added a secondary zone, using the new server is that incorrect do i need to change it back to the main ip?

    name servers ip1 ip2
    Main DNS 1800 IN NS 1800 IN NS 1800 IN A ip1 1800 IN A ip2 1800 IN A ip1
    * 1800 IN A ip1 3600 IN A ip1 3600 IN A ip2 3600 IN A ip1 3600 IN MX 10

    Master Host Files localhost
    ip1 central

    Slave Host Files localhost
    ip2 web

    The /etc/hosts file has nothing to do with DNS.
    I hope you are not doing stuff and hoping it works, and then ask forum when it does not. And using punctuation would make your text more readable.
    The intodns error seems clear: one or more of the name servers registered for your domain does not work, in other words is it not answering name service queries.
    What exactly happens when he/she tries? What domain is the one used in that URL? Usually one webmail URL is set up for all customers, so webmail works at https://email-server.serverdomain.tld/webmail. Tell that client to use same URL as other clients for accessing webmail.
    The DNS tutorial in my signature has paragraph on troubleshooting DNS problems, try that and then hopefully ask better questions.

    @Taleman, no i have read the documentation over and over, i even bought the manual. I apologize if my question seem like a trial error but it was from the documentation my understanding it worked liked that, i guess i just read it wrong. I am not try to do random stuff i just want to get this new server and not mess around with the server only to add new servers. My wife also complains about my english i apologize im mexican spanish is my first language.

    Ill revert the to the main ip again, can i remove that service from the slave, from the documentation its my understanding you must configure dns all installs on slave servers.
    I clicked on the link, ill checked it out but i think im just gonna leave it for now since its working

    This worked,https://email-server.serverdomain.tld/webmail
    the installation said https://email-server.serverdomain.tld:8081/webmail sorry about that
    also on the main ispconfig i access the email by,

    One last question
    What i did would be multi server correct and not clusters. I dont understand the mirror option i been reading on the forum that everybody keeps talking about

    Mirror means that tow servers do the same thing. This is used when you either have high load and want to spread the load on multiple servers by adding a load balancer in front of the servers or it is used to get a high-availability setup.

    Or in the case of DNS servers, it is used to automatically propagate the DNS records to all name servers so that the other servers can act as a secondary DNS. As alternative, you can use secondary dns records. But take care that you add secondary records only on the secondary dns servers, if you would add it on the primary dns server together with the primary records, then BIND will fail and you get a dns error.
