    Hello,

    I wanted to know if it was necessary to create a DNS zone for the hostname in order to benefit from SPF/DKIM...etc because I have problems with emails coming back "Undelivered Mail Returned to Sender".

    Thanks
    Seb

    Zone for hostname, maybe your question is not formulated properly?
    My signature has link to e-mail setup tutorial, maybe it answers your real question?
    There is also this: https://www.howtoforge.com/ispconfig-email-account/

    Thank you for your quick response.
    I watched the tutorial and everything is as per this document on my end.
    So if I understand correctly, there is no point in creating a DNS zone for the hostname, because the SPF and DKIM verification is done on the domain name belonging to the email box that sends the email, not on the hostname?

    Correct.

    And in general, the hostname must be a subdomain like server1.yourdomain.com and you do not create a zone for subdomains. So the hostname is just a A-Record in the zone of the domain the subdomain belongs to. So when your hostname is server1.domain.tld, then server1 is just a A-record in the zone domain.tld and not a separate zone.

    Ok, but my hostname is totally different from the site domain and mailboxes created with the domain. For example, I have hostname abcd.com and my site domain is blablabla.com

    Basically all are fine except that a hostname must be a subdomain as mentioned by @till above.

    That's fine and usually the case. What I described applies in exact that case that you have. But the hostname must be a subdomain as you can not use the (main) domain for websites and email otherwise, which would not make sense.

    my host name is indeed a subdomain but it does not belong to the domain name of the website and email boxes created on ispconfig. totally different. Is it good though?
