Hi, I have faced the similar problem. In my case SELINUX was the culprit. Please disable the same if you are using Redhat linux and if you SELINUX is set to other than disabled.
Edit /etc/sysconfig/selinux and set SELINUX=disabled Sincerely, Sree ----- Original Message ---- From: João Luiz - Terra <[EMAIL PROTECTED]> To: firstname.lastname@example.org Sent: Thursday, 11 October, 2007 7:49:20 AM Subject: [vchkpw] qmailadmin "invalid user" Hi, Sorry.
