Done, playing with it now.

Not as worried, it's a small personal system.

Since I'm the main user... I get to beat myself up.  


So here's a question.  The 2.3 to 2.4 converter suggests this small
snippet of proposed configuration:

    mail_driver = maildir
    mail_path = /var/mail/%{user | domain}/%{user | username}/Maildir
    managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress compar
    protocols = imap lmtp sieve

    sieve_script personal {
      driver = file
      path = ~/sieve
    }


Will the 'sieve_script personal { ... } ' block work ok with it's path
being ~/ and will it inherit the mail_path defined farther up?  Right
now under 2.3 it creates the following:

      /var/mail/stoffel.org/john/sieve/
      /var/mail/stoffel.org/john/Maildir/

directories, but I think I need to add in for 2.4 the following:
 
    mail_home = /var/mail%{user | domain}/%{user | username}/

And then the sieve_script_personal will work properly.  Is this
correct?  And no, I haven't tried it yet, working on deploying my new
test VM.

Now my old system is configured to use sqlite3 as the backend
mechanism, and I see that it does define the following queries:  

   driver = sqlite

   password_query = SELECT email as user, password FROM virtual_users WHERE email='%u';

   user_query = SELECT '/var/mail/%d/%n' as home, 'maildir:/var/mail/%d/%n/Maildir' as mail, 'mail' AS
   uid, 'mail' AS gid FROM virtual_users WHERE email = '%u';

   iterate_query = SELECT email AS user from virtual_users;

and I think the 'user_query' returning the 'home' value and the
correct directory would do the right thing and mean I don't need to
explicitly define mail_home.  

Is this true?

Thanks,
John
