You are welcome!

There is a drawback to this scheme, however: when you have to resort to
creating virtual domains with mailboxes in c:\imail\users (same as for main
domain), you'll have to create two accounts for every new user who belongs
to the group of domains that exceeded 25-255 rule.

One account will be for the main domain and another one - for the virtual
domain. These accounts will share the same mailbox, so whatever is delivered
to virtual domain or its alias can be pulled from the main domain.

If you need more details, feel free to e-mail me.
