Problems with postfix & virtual mail

Hello

I've been reading the howto's from high5.net/howto &
kirb.insanegenius.net/postfix.html. Again, again & again.

After many late nights I've succeeded in setting up a more or less workin=
g
configuration.
Nevertheless, I've some problems & some questions, hope someone can help =
me, as
I may be close to the solutions but still too far away.

First the problem, because that's most important.
If I use the following conf:
mydestination =3D $myhostname
everything works fine if I use webmail on the same machine. I can mail to
virtual users, ok.
But the server does not relay mails (try for yourself: peter@sugar.be) if=
I send
from another domain.

Then I can change my conf to
mydestination =3D $mydomain, $myhostname, $transport_maps
But then I cannot send mail to virtual users if they don't have a corresp=
onding
real user (in /etc/master.passwd), but I want to keep the users completel=
y virtual.

Now I think I've found a working solution, but not sure if it's a good on=
e:
-bash-2.05b# postconf -n
command_directory =3D /usr/sbin
config_directory =3D /etc/postfix
daemon_directory =3D /usr/libexec/postfix
local_recipient_maps =3D=20
mail_owner =3D postfix
mailbox_size_limit =3D 51200000
mailq_path =3D /usr/bin/mailq
manpage_directory =3D /usr/local/man
mydestination =3D $mydomain, $myhostname, $transport_maps
newaliases_path =3D /usr/bin/newaliases
queue_directory =3D /var/spool/postfix
readme_directory =3D no
sample_directory =3D /etc/postfix
sendmail_path =3D /usr/sbin/sendmail
setgid_group =3D postdrop
transport_maps =3D mysql:/etc/postfix/transport.cf
virtual_gid_maps =3D mysql:/etc/postfix/gids.cf
virtual_mailbox_base =3D /
virtual_mailbox_maps =3D mysql:/etc/postfix/mysql_virt.cf
virtual_uid_maps =3D mysql:/etc/postfix/uids.cf

Is this OK, is it safe to just disable local_recipient_maps (I found it i=
n the
FAQ)???




Maybe you're tired reading this awful post, but I still have some questio=
ns. It
would be very kind if you read these too!

/var/spool:
drwxrwxr-x 5 postfix postdrop 512 Feb 2 12:32 vmail
/var/spool/vmail:
drwxrwxr-x 2 postfix 2001 512 Feb 2 12:32 hip.be
drwxrwxr-x 5 postfix 2002 512 Feb 2 17:05 sugar.be
/var/spool/vmail/sugar.be:
drwx------ 3 2003 2002 512 Feb 2 17:05 malakai@sugar.be
drwx------ 3 2000 2002 512 Feb 2 12:48 peter@sugar.be
under these directory's there's always a directory Maildir

Are these permissions correct? What should be the homedrive, what the Mai=
lDir in
the db?
I have now:
peter@sugar.be(UserID)
2000(VirtualUID)
2002(VirtualGID)
/var/spool/vmail/sugar.be/peter@sugar.be (HomeDir)
/var/spool/vmail/sugar.be/peter@sugar.be/Maildir/ (MailDir)

What's the difference between homedir & maildir, and how does courier-ima=
p
handle this? I expected that if I create a directory as a user in squirre=
lmail
(or imapclient), it would be created in the homedir. But if I want to cre=
ate a
folder imap says "Invalid mailbox name".




Best regards

Peter
