PHP forms are not working for Emails on Remote Server

[Emiliano]

Hello,

I have a cpanel account and the emails for that cpanel account are on a different server where the emails are pointed with MX records from the Domain settings on the domain registrar.

Now, I have created a few php forms that send emails to the emails set up on the MX server but the emails are not being delivered to that MX server.
I have also tried to change the email on the forms to other emails that i have on the cpanel server and emails there work perfectly fine. Also they do send emails to yahoo/gmail/msn emails without problems.

The problem is that although the MX emails work fine they can't receive emails from submitted PHP forms.

Anyone has encountered this issue previously, that can help me?

I have CSF, CXS firewall and cpHulk installed.

Thank you

WHM -> Edit DNS Zone -> Choose the domain where the email is hosted remotely -> At the bottom select 'remote' -> Save
[or]
cPanel -> MX Editor -> Choose the domain where email is hosted remotely -> Choose 'remote' -> Save

Hello ,

First contact your hosting provder and ask them to check the mail logs of your account so that you can find out the exact cause of your mail issues. Also I will suggest you please use SMTP authentication in your php forms mail setting and check it.

Do the php forms use smtp or php mail()?

Hello

Yes, please ensure you select "Remote Mail Exchanger" under "Email Routing" via "WHM Home » DNS Functions » Edit DNS Zone" or "cPanel - MX Entry".

Thank you.
