Helps to send emails to the same domain

[guidolin]

Hello,

We configure a Vesta to send emails, however it will only be used to send emails from a system, and we are authenticating with a user such as: [email protected]

How do I get @domain.com users to also receive these emails? Are the @domain.com emails on another server, and are they not used on Vesta?

Error showing in log:
More /var/log/exim/main.log | grep 1cnncY-0006cL-JU

In Cpanel, we have the option to choose in MX if the email is local or remote, in Vesta we have this option?

Thanks.
