Check your root crontab entries. I remember something about redhat running a cleanup that removed the entries needed for vpopmail.

I've configured qmail, vpopmail and qmailadmin on a redhat system box. I've configured multiple domains on vpopmail and created mailboxes for that on qmailadmin.
However, a few hours after configuration, password for emails ( and postmaster too ) do not work, i have to reconfigure all domains again. That is happening a lot, i'm configuring emails every 2 hours...
Any ideas on what that could be?
