while sending the emails check the logs at /var/log/exim/main_log and that will give you an idea of whats happening while sending the mails.

rDNS Setup

To what other providers you are referring to? Gmail, Hotmail, or any other ?
First check what MX record your domain has.
Second check if you are able to perform a local mail delivery to the some other account on the same server.
Third try to send an email to non-standard email domains (not Gmail, Hotmail, etc).

Check if the mail delivery to the other non-standard email services goes properly from the domain on your server. Check the email logs at the location /var/log/exim_mainlog and not in /var/log/exim/main_log..

Hello,

The following document is a good place to start:

How to Keep your Email Out of the Spam Folder - cPanel Knowledge Base - cPanel Documentation

As far as the RDNS entry, you may want to reach out to your hosting provider to have them verify the RDNS entry is properly configured.

Thank you.
