Question how to (dns)

[GravuTrad]

Hi

I have several questions about dns configuration (and where to act to solve it):

dns tests give this (names changed):

"
NOTICE: We found name servers without AAAA records.

• ksmyserver.kimsufi.com. → ?
• ns.kimsufi.com. → 2001:41d0:3:1c7::1

To reach your name servers via IPv6 an AAAA record is needed for each name server."

"
WARNING: Found mail servers with inconsistent reverse DNS entries. You should fix them if you are using those servers to send email.


Server IP PTR (Reverse) IPs

mail.mysite.com. ipv4mysite ksmyserver.kimsufi.com. myipv4

mail.mysite.com. ipv6mysite ? ?

All mail servers should have a reverse DNS (PTR) entry for each IP address (RFC 1912). Missing reverse DNS entries will make many mail servers to reject your e-mails or mark them as SPAM.

All IP's reverse DNS entries should resolve back to IP address (IP → PTR → IP). Many mail servers are configured to reject e-mails from IPs with inconsistent reverse DNS configuration."

"
Mail Greeting
NOTICE: I've found differences between mail server host names and greeting host name. The following mail servers claims to be other hosts (reverse DNS checks may be wrong):

• mail.mysite.com. → ksmyserver.kimsufi.com

"
"Accepts Abuse Address
WARNING: Found mail servers which are not accepting emails to [email protected] address:

• mail.mysite.com.
  >> MAIL FROM: <[email protected]>
  << 250 2.1.0 Ok
  >> RCPT TO: <[email protected]>
  << 550 5.1.1 <[email protected]>: Recipient address rejected: User unknown in virtual mailbox table

"No ip literal"

How could i repair all this and where please? (server side, and/or domain registrar side)

Thanks for advance.

Hi GravuTrad,

your entries for your domain, are done over the Control Panel of your domain registrar. Your Plesk Control Panel is not the initial nameserver for your domain, it's the one of your domain registar ( or if you use Cloudflare, or another CDN - provider, then it's their nameserver(s) ).

Noted. And for the abuse email address and the literals ips?

Hi GravuTrad,

And for the abuse email address

Well... it's up to you, if you use DMARC - entries for your domain and use as well the standard "abuse" - mail - adress ... it's rather an information, because this standard is not setup all over the world yet, but only recommended!


Possible DMARC - entry ( you may use the online configurator at for example: http://www.kitterman.com/dmarc/assistant.html ):

Hostname: _dmarc.YOUR_DOMAIN.COM
TYPE: TXT
VALUE: v=DMARC1; p=none; rua=mailto:abuse@YOUR_DOMAIN.COM; ruf=mailto:abuse@YOUR_DOMAIN.COM; fo=0; adkim=r; aspf=r; pct=100; rf=afrf; ri=86400; sp=none

Pls. be sure to configure the desired "abuse" - mail - account, so that eMails to this account can be delivered.

literals ips?

Pls. ask in detail, what you would like to know, because I didn't understand this. If you desire to ask again, HOW a reverse record has to be set, pls. have again a look at your DOMAIN REGISTRARS Control Panel and be reminded, that if you use for example "kimsufi", you can setup the reverse to your IPv4/IPv6 over their Control Panel, but make sure, that you previously setup the desired FQDN over your domain registrars Control Panel.

It's surely related to the FQDN. How to set up it correctly? thanks.
