I have a website hosted on a webhosting on a shared server with cPanel access.
The website has a “contact us” form to fill for us to receive an e-mail using PHPMailer.
Our e-mails are not created in cPanel, they are Google Apps (Gmail).
All works perfect until an automatic update is made in cPanel.
When it happens, the MX record is set to localdomain instead of Google servers, and we stop receiving e-mails.
That seems a bit silly to me, but I don’t know much about this stuff. CPanel has been updated on my server quite a few times and the MX records haven’t been changed (and I’m using Apps like you). Can you turn off auto updating?
