Sentora, problem sending an email arrives in the spam box
I have a droplet with sentora, the problem I have is that when sending an email this arrives in the spam box (I did the tests of sending mails to gmail and Outlook).
I have configured the DNS of the Digital Ocean as follows
A - mail - IP - 3600TTL
MX - mail.dominio.com - 10 - 3600TTL
TXT - dominio.com - v=spf1 mx ~all - 3600TTL
I also use the NS of digital ocean
I made the same setting in the DNS Manager for the sentora.
I hope you can help me.
