How to Check Whether a cPanel Site Is Sending Mail From the Correct Address

11/10/2026

A website may send from a default or outdated address even when the contact form shows a different sender. This can affect delivery and domain authentication.

What to check

Inspect application mail settings, envelope sender, From and Reply-To headers, SMTP account, and domain authentication alignment. Send a test to a controlled mailbox and review headers.

Recommended next step

Use an authorized sender address and keep the visitor address in Reply-To when appropriate. Informatix Systems can troubleshoot cPanel email and website forms.
