If you mean, are the affected users all in domains vhosted under ISPConfig, the answer is yes.
DocumentRoot is /its/isp/hosted. Mail for email@example.com
should be going to /its/isp/hosted/www.affecteddomain.com/useraffecteddomain.com_user/Maildir/new, is instead going to /var/mail/affecteddomain.com_user.
The handful of users experiencing this problem are constant - it's always the same 6 users, and all messages sent to these 6 users go to /var/mail. When new users are added, they experience normal mail delivery.
