<p>Thank you for the information, your permissions look good.<br>
</p>
<p>I think I see the problem. There is step on the MIME parsing in
this check that assumes that the email contains a regular body.
This is not always true.</p>
<p>I will prepare a patch.<br>

from 5.0.3 to the latest. OS is CentOS 7. So, the directory
permission remains unchanged. SELINUX is in permissive mode.
MailScanner runs as user postfix. By the way, Is there a way
of disabling QP DOC Checking? For your information, here it
