# doveadm user flindner
userdb lookup: user flindner doesn't exist

flindner is my linux system user. There are virtual user, e.g

# doveadm user spam at xgm.de
userdb: spam at xgm.de
   home      : /home/flindner/Mail/spam
   uid       : 1001
   gid       : 1001

/home/flindner/Mail/spam is the home and maildir of virtual user.

My mail system is built like that:

postfix delivers all mail of a domain to maildrop using a system user 
which have this domain assigned. maildrop does the final delivery. There 
is no 1:1 mapping of mail adresses to maildirs.

postfix @xgm.de -> maildrop flindner -> maildrop -> maildir <- dovecot 
IMAP  this should become:

postfix @xgm.de -> maildrop flindner -> maildrop -> dovecot-lda -> 
maildir <- dovecot IMAP

so that I can also use sieve for filtering.

Florian
