[Dovecot] deliver LDA permission problem

[Dick Middleton]

Hello,

	I'm trying to get deliver LDA working with postfix in a virtual domain 
configuration.

I'm using dovecot v1.0.rc10.  My setup is pretty much exactly as in the wiki 
(only the path to deliver and auth-master socket are different).

I'm having a little problem with permissions and this occurred which I think is 
undesirable:

syslog:

Feb  8 13:09:35 deliver(<email-addr>): setgid(5002) failed: Operation not permitted
Feb  8 13:09:36 deliver(<email-addr>): setgid(5001) failed: Operation not permitted

mail.log:

Feb  8 13:09:36 Devil postfix/pipe[9622]: 5AD5C103C: to=<<email-addr>>, 
orig_to=<<email-addr>>, relay=dovecot, delay=0.05, delays=0.01/0/0/0.04, 
dsn=5.3.0, status=bounced (Command died with status 89: 
\"/usr/libexec/dovecot/deliver\")


When deliver fails because it can't connect to auth-master socket it returns an 
undeliverable status which causes postfix to defer delivery.  I think it should 
do the same here.

The real question is how I give deliver the permission to do the setgid?  Is it 
enough to just add user vmail to each of the virtual user groups in /etc/group.

Does deliver setuid to virtual user as well?
