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? > > > If I'm understanding things correctly, the next, very important item, is > > how do I setup new users and how would those users then manage things > > like passwords, etc.? > > This is up to you. dovecot does not provide and user interfaces for > managing accounts (that I am aware of).

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. Andy
