Yuri,
I had not thought of that. That will solve so many problems for me.
Thank you,
Jeff

You can double and triple 25-255 rule for domain aliases if you create some
virtual IP-less domains with user directories in the same place as in the
main domain. Then the administrator can alias virtual domain(s) to his
heart's content.
