Mail Server does not accept email from NULL senders?

[Clixer]

Hello folks,

I recently setup a Cpanel/WHM VPS with a hosting provider. After the setup, I ran a DNS/email check using network-tools.webwiz.net/dns-report.htm. The report shows two errors which is of concern to me, they are:

1. Connect to Mail Server <server> A error occured connecting to your Mail Server <server>.

2. Acceptance of NULL Sender to <server>. Your Mail Server <server> does not accept email from NULL '<>' senders.

Wondering what is the cause of these errors? Please not that I am able to send and receive emails from the server.

Thanks for help.

Hello,

The same results appear when testing any domain name using the default cPanel configuration. This should not result in any issues with mail acceptance. Generally, the default setup is suitable, aside from ensuring you follow the guidelines we document at:

Thank you.
