Thanks for this link. I think it will be helpful, though at this point, I'm
overwhelmed.

Ok, if I may run this by you, I've made a user id for this virtual mail stuff,
the virtual mail user is "vmail." Yes I know, very inventive. The users
home directory is /usr/home/vmail, but I'm thinking that what dovecot cares
about is where mail is stored. In this case, I'm pretty sure
it's /var/mail/vmail.
I've followed the instructions in http://wiki.dovecot.org/AuthDatabase/SQL and
created the table as defined on this page. If my understaning is correct,
this field will contain the entry "/var/mail/vmail," correct? Further, if
I'm following, dovecot somehow delivers all mails to this virtual user and
somehow categorizes them according to the virtual users? Does this sound
correct?
I wonder, sometimes attachments get large, if I'm anywhere near correct, I
wonder if I should use a directory under /usr instead of /var?

Ok, that makes it simpler though some additional work for me coming up with an
easy way to add people to the list.
Thanks for all the help.
