How to configure DNS record for allow email sending from different domain

Question

Hello everyone I'm Italian and I apologize in advance for errors that read as follows :)

I'm starting to use a newsletter service (easymail-pro .it) that sends email using my domain name but by a different host. I need to istall the dkim and spf records that have sended me, but when I install the records, all email that i send directly by my domain go to spam. My records are:

TXT - key_14046._domainkey.domainname.agency - v=DKIM1; k=rsa; - 300
TXT - domainname.agency - v=spf1 a mx ~all - 300

I don't know what key_14046 mean, many time ago when i started to configure mail server, mail-tester .com suggested me to add this record and it worked fine

These are the record that easymail-pro .it say me to install

SPF:    domainname.agency IN TXT "spf2.0/pra include:x6h***1.com ~all"
DKIM: v=DKIM1; k=rsa; p=MIGfMA***************************gQDPQsoOji9HBmGxtkyU4BqLBAsCN/cJfJp+6vbMazf88I4KRKYw80kYoXl6EME0tubD4VHhK6Mmj*****************7DlcIxQIDAQAB 

When I add the records of easymail-pro .it my email goes spam and when i test my email with mail-tester .com i receive many error.

if i add more than one spf record not working so I've tried to mix SPF in this way "v=spf1 a mx include:x6h***1.com ~all" but still not working

What is the way to configure correctly the DNS Record??

Answer 1

In the authoritative DNS for your domain:

your.domain.here    IN  TXT "spf2.0/pra include:x6h***1.com ~all"
                IN  TXT "v=DKIM1; k=rsa; p=MIGfMA***************************gQDPQsoOji9HBmGxtkyU4BqLBAsCN/cJfJp+6vbMazf88I4KRKYw80kYoXl6EME0tubD4VHhK6Mmj*****************7DlcIxQIDAQAB"
