    Hi @Taleman Ok, thanks, I didn't realize that it was also necessary to configure DNS zones in ispConfig itself.

    In my mind, as I kept the dns management at my hoster, everything was configured at Ovh and I just had to point the services to the ispConfig machine.
    But I understand that ispConfig also needs to route requests.

    It is not necessary, if zones are at your hoster. Or somewhere else.

    You indeed don't have to add the zone in ISPConfig. You should undo that change(s). @Taleman said there was a explanation about PTR aswell in that tutorial, and you should check that. But that should have nothing to do with your current ISPConfig installation.

    Ok, I understand, I'm reading the Taleman Howto " https://www.howtoforge.com/how-to-install-an-email-server-with-ispconfig-on-debian-10/"

    I think I'm close from the solution to sending mails ;
    Code:
    host 163.172.143.149
    149.143.172.163.in-addr.arpa domain name pointer srv-b.democrasite.com.
    Code:
    host democrasite.com
    democrasite.com has address 163.172.143.149
    democrasite.com mail is handled by 5 srv-b.democrasite.com.
    democrasite.com mail is handled by 1 srv-b.democrasite.com.
    iMacdeEitan2018:~ nabpb2018$ dig srv-b.democrasite.com |grep "ANSWER SECTION" --after-context=3
    ;; ANSWER SECTION:
    srv-b.democrasite.com.    3600    IN    A    163.172.143.149
    
    Code:
    [email protected]:~# hostname -f
    srv-b.democrasite.com
    
    and at my hoster, my VPS shows this :
    Code:
    IP address:        Reverse:
    163.172.143.149    srv-b.democrasite.com.

    Okay, now you have to set a reverse DNS record (PTR) for your IPv6 address aswell.

    WhaaaaooooooOO :D I get 10/10 : https://www.mail-tester.com/test-gu4kxboi0
    when sending from Rouncube on server, so I think I have another problem with my Thunderbird, he says :
    Code:
    Error sending the message :
    
    Sending the message failed.
    The certificate is not secure because it is self-signed.
    The configuration related to srv-b.democrasite.com needs to be fixed.
    Not configured SSL certs for smtp I guess ;-)

    Mmmm… You mean, I need a AAAA entry in my dns zone ?

    You indicate at this step :
    Code:
    Go to ISPConfig Panel System tab, Interface Main Config and Mail tab. There set
    
    Use SSL/TLS encrypted connection for SMTP
    to SSL.
    to activate the ssl for sending smtp. For SmtpUser and Smtp psswd, do I put what I want or does it have to be an e-mail account login and password already created in ispConfig?

    thank you

    Leave them empty and SMTP host: as "localhost". They are for forwarding e-mails to another e-mail server, and e-mail account and password there. I'm sure these are explained in the ISPConfig Manual.

    :D Probably yes... I bought the manual, but I haven't had time to read it all yet, my apologies --°

    But if I let it blank > "Please enter the admin name and admin mail address if you want to use smtp mail sending"

    No, you need a reverse DNS record for your IPv6 address, the same way you set it up for your IPv4 address.
