Hey,

Could someone help me please?

I just tested my mail here http://www.mail-tester.com/

and here is the 0/10 result: http://www.mail-tester.com/web-8g7q9

I'm using cloudflare so I just copied DNS that plesk gave me, when I added the domain.

I have no idea how to correctly set up DNS

Hi Bogdan1,

I have no idea how to correctly set up DNS

First, pls. be informed:

vps343915.ovh.net resolves to 164.132.48.211
but
164.132.48.211 resolves to 211.ip-164-132-48.eu​

You should consider either to change the reverse entry for your IP ( contact OVH pls for such a desire ) or/and consider to change the standard "vps343915.ovh.net" hostname on your server to your main FQDN ( "mactrh.cz" ) "YOUR-DESIRED-HOSTNAME.mactrh.cz" ( don't forget to create a corresponding "A" - entry on your primary nameserver, according to your "YOUR-DESIRED-HOSTNAME" ) and afterwards, ask OVH - support to reverse the IP to the new hostname, or use the ( possible ) options on THEIR Control Panel, to reverse a rented IP to a desired hostname.


Second, you added an obsolete SPF - entry, in addition to your TXT - SPF - entry. Pls. note that such entries should be removed by now, according to "RFC 7208" ( => https://tools.ietf.org/html/rfc7208 ).

3.1.  DNS Resource Records

   SPF records MUST be published as a DNS TXT (type 16) Resource Record
   (RR) [RFC1035] only.  The character content of the record is encoded
   as [US-ASCII].  Use of alternative DNS RR types was supported in
   SPF's experimental phase but has been discontinued.

   In 2003, when SPF was first being developed, the requirements for
   assignment of a new DNS RR type were considerably more stringent than
   they are now.  Additionally, support for easy deployment of new DNS

​

Third, your current TXT - SPF - entry is valid, but very STRICT ( "v=spf1 +a +mx +a:vps343915.ovh.net -all" ). You should consider to use:

v=spf1 +mx +a a:vps343915.ovh.net ip4:164.132.48.211 ?all

(or, when you change the hostname as suggested above! ):

v=spf1 +mx +a a:YOUR-DESIRED-HOSTNAME.mactrh.cz ip4:164.132.48.211 ?all​

Thanks, If I use reverse dns domain that OVH gave me 211.ip-164-132-48.eu as hostname, it would be ok?
If I have also ipv6, Should I type spf like this:
v=spf1 +mx +a a:vps343915.ovh.net ip4:164.132.48.211 ipv6:2001:41d0:401:3000:0:0:0:2c86 ?all
or
v=spf1 +mx +a a:vps343915.ovh.net +ip4:164.132.48.211 +ipv6:2001:41d0:401:3000:0:0:0:2c86 ?all

is there any differences with or without (+)?

Hi Bogdan1,

well, pls. read again, what I wrote above, because I already mentioned that this should be corrected.

v=spf1 +mx +a a:vps343915.ovh.net ip4:164.132.48.211 ipv6:2001:41d0:401:3000:0:0:0:2c86 ?all

This would be correct.
