[Dovecot] deliver is curious

[Nikolai Bochev]

I've had exactly the same problem. My home folder was a separate
directory under /home/vmail/%d/%n . The mails were in /srv/mail/%d/%n
and i had exactly the same behavior . The error went away when i moved
the home folders under /srv/homes/%d/%n. The weird thing is that if the
user had sieve scripts ( created by Ingo ) the home folders did exist
and everything was fine for that account. However if a user didn't have
a home folder created before a delivery of such email it would fail. I
guess it was some permission issue, but :

root at mail:/usr/src/dovecot-1.2.2# ls -lha / | grep vmail
drwxrwxrwx   8 root  vmail 4.0K 2009-07-13 02:16 home
drwxrwxrwx   5 vmail vmail 4.0K 2009-06-15 10:41 srv
root at mail:/usr/src/dovecot-1.2.2# ls -lha /home | grep vmail
drwxrwxrwx  8 root     vmail    4.0K 2009-07-13 02:16 .
drwxrwxrwx  6 vmail    vmail    4.0K 2009-07-08 17:34 vmail
root at mail:/usr/src/dovecot-1.2.2# 


You can see the difference, but i didn't want to change the ownership
of /home to vmail user. Not sure what i did wrong or what i did right
after that but that's how i fixed it.
