Hello

When a customer sends a support service message from my whmcs website, I get the following error message. A warning mail is not sent to the customer. I am getting error message as below.
Email Sending Failed - Email Sending Failed: The following From address failed: [email protected] : MAIL FROM command failed,Sender address rejected: not owned by auth user. 1644672657-rHjwD7uH5n-UvH4BfpR ,553,5.7.1SMTP server error: MAIL FROM command failed Detail: Sender address rejected: not owned by auth user. 1644672657-rHjwD7uH5n-UvH4BfpR SMTP code: 553 Additional SMTP info: 5.7.1 (Subject: [Ticket ID: 471635] destek 12)

SMTP error on contact forms

Hi guys, I have a problem with my contact forms, both Contact Us and Support tickets. I get the error "Sender address rejected: not owned by user". All other notifications, sales etc are coming through and sending ok, it's just the contact forms. Not sure if I've missed a setting somewhere?
