After much anguish trying to fix problems of a new migrate and upgrade we know the /etc/vmail folder is created by reading the /etc/userdomains file and it makes all the stuff needed for users to get email. One thing I dont know is how the userdomains file is made. It appears to be sorted alphanumerically so it wasnt created as we added accounts. My concern is whatever made it the last time it got screwed up, will create it again. Anybody know what makes it and when its done ?
