Webmail + cloudflare and SMTP website

Hello .

I just installed hestiacp on my aws server cloud and i use cloudflare. I use it as an smtp server sendinblue.
I can send emails from webmail, but I don’t receive emails back.
my cloudflare dns

What exactly did I do wrong?

It is missing mail.domain.com and it should be DNS only


I add and its the same…no work.

What is the domain you are using?

sed -i "/zen.spamhaus.org/d" /etc/exim4/dnsbl.conf
systemctl restart exim4
