Hi. I have an installed ticketing system on my server and have multiple customers on it. All notification emails receive correctly to them. But there is just one customer that can not receive these emails. I tested sending email to his email address through webmail and also with php mail() function, and the same result occurred. All of those email failed instantly after submit.
The message in failed email is like this:
Note: [email protected] is a sample email address here.
Target email address is correct and can receive all emails from other servers. On the other hand, all other targets can receive my sent email. So the problem is only between my server and that customer's server.
Can you help me to solve this problem?
