    I cannot receiver or send emails, is it the dkim
    digitalocean droplet

    webmail with roundcube

    checkbox is checked for
    Use SMTP to send system emails under main config
    under stmp but values are empty are those supposed to be filled out

    According to the two zones you posted: the domain has a valid dkim setup, the domain has no dkim.

    I don't know what the dkim digitalocean droplet is or which prerequisites it has. You might want to contact the digitalocean support if you have any issues with their preconfigured droplet.

    I added the host and the main domain should i add the dkim to the droplet
    should i add it to the host and main domain dns then droplet?
    also if i add it does that configuration look correct?

    ok im reading it, but can you explain if all what i added in digital ocean, does it even matter or ipsconfig takes care of that because, cause it says dns viz something and i am confused, about the parent zone
    only reason i want to use my, is because i have over 80 sites and dont want to go into each and change the dns

    is there a link or something that can dumb it down even more, i have looked thru dozens of tutorials
    i even bought the manual but i still cannot find something where it says to point this ns1 or just add ip to nameservers if etc...

    and the tutorials i found everybody does it different just want to know what the proper way to do it

    the manual does not explain it or really go over actually what you need to do with ns1 etc..., if its in spanish i can give it a try, can i use ip6 as a second dns but dont think that would help

    i been trying for weeks, and nothing this is my 20th install

    question does the ispconfig work the same as cpanel as in using the droplet info to create mx, mail, etc...

    or diffrent

    Seems you only have one name server, since ns1 and ns2 have same IP-number.
    Did you set up name service on your ISPConfig host? Which host is that, is it the one with IP-number
    There is Tutorial:
    To get sending of e-mails working, the MX host must have reverse DNS PTR record matching the hostname. Your MX does not:
    $ host has address
    $ host
    Host not found: 3(NXDOMAIN)
    Also, show what
    hostname -f
    return on your host. If you have only as hostname -f, it causes problems with mail server setup. If you have one ISPConfig server, set hostname to

    looks like i got it, but i have some errors here, can you check it out also was my old domain
    do i need to have on dns zones or dont matter

    here is a site i added
    email to test
    [email protected]

    is this to much mumbo jumbo or pretty much correct way on a single server




    let me know if that works,
    if yeah so i can start creating a spanish tutorial and start translating the to spanish

    I do not understand what you are asking.
    But mundocafe is working in DNS:
    host has address mail is handled by 10
    host has address
    host domain name pointer
    I cant say whether that works or not. Those test websites you already used should tell you if they work.

    actually it worked this time with no more errors, email is working, im receiving email as well as sending, and have everything like dkim

    but for the sites you sent i have these errors

    but does not show this, so im confused how these two sites are saying the errors

    It shows error "ERROR: No reverse DNS (PTR) entries":
    it seems you should configure you reverse IP inside DigitalOcean. Don't know that provider, I suppose they should have a panel with some option in where you can assign your server name ("" or whatever) to the ip

    Do a #hostname to know the name of your machine, then go inside DigitalOcean panel and assign
    Wait some time and then check you IP returns your server name :

    I believe there is a confussion in your config using the dns ip from digital ocean and the ip of your server. Maybe you should look assistance in digitalocean

    thank you figured it out,
    so added extra name servers in

    then in digitalocean i created two dns with ns1 digitalocean, ns2 digitalocean and then added 2 a records and pointing to my ip 1800 IN NS 1800 IN NS 1800 IN A IP Address 1800 IN A IP Address 3600 IN A IP Address
    * 3600 IN A IP Address 3600 IN A IP Address 3600 IN MX 10 3600 IN A IP Address 3600 IN TXT "v=spf1 a mx ip4:IP Address -all" 3600 IN TXT "v=DKIM1; etc..." 3600 IN TXT "v=DMARC1; p=reject; rua=mailto:[email protected]; ruf=mailto:[email protected]; fo=0:1:d:s" 3600 IN CAA 128 issue """"
