service-specific userdb affecting lmtp, quota-service

[Michael Fox]

Update:

I was able to eliminate the /var/log/mail.err error messages (shown below)
by creating a userdb.quota-status and userdb.lmtp passwd-file.  However,
since userdb.pop3 and userdb.imap will have different extra-fields values
for namespace (different namespace/xxx/inbox=yes values) I can't simply
create userdb.quota-status and userdb.lmtp as the union of userdb.pop3 and
userdb.imap.  At a minimum, the extra-fields namespace info has to be left
out.  

So this creates the question:  For each service, which fields does the
userdb need to contain?  I can't find that documented anywhere.

For example, for the quota-status service, I presume the following are
needed:
-- username
-- home directory  (since mail_location = maildir:~/Maildir)
-- any "quota=" overrides in the extra-fields
-- nothing else

Is that right?


And I presume userdb.lmtp needs to return:
-- username
-- home directory  (since mail_location = maildir:~/Maildir)
-- nothing else

Is that right?

Thanks,
Michael
