Sentora, problem sending an email arrives in the spam box

Hi. 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 - - 10 - 3600TTL TXT - - 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. Thank you

There’s no reason to have the settings in Sentora also, since you’re using DigitalOcean’s name servers, so it should be enough to have the configuration there.

Have you set your PTR (reverse DNS)? It should be

It takes time to setup a good configuration, so you don’t end up in spam folders - it would be recommended that you setup DKIM too (not sure if that’s a feature in Sentora).

Try sending a mail to to figure out what you should focus on. Just ignore statements about HTML and stuff like that, since the tester is made for newsletters.
