You need to match the groups used by deliver in the master.cf
(mail/mail) or change them there. Try
virtual_gid_maps = static:8
virtual_uid_maps = static:8
Ok, here is a configuration that works fine but without success to
retrieve the correct gid in the database.
The mails are stored under www-data:www-data in place of www-data:gid.
The parameter virtual_gid_maps = proxy:mysql:/etc/postfix/mygid.cf has
no effect.
But it's working, thanks !!

if that is apache user then you have open file system for remote web users to

dont save your mails with apache user

If you continue to have problems, ask for help on the Postfix mailing list. On debian lenny, using dovecot 1.1.13-2~bpo50+1 I try to configure my setup (with Postfix virtual domains) to use dovecot as lda but nothing happens, as if postfix not delegate to dovecot This is because you never configured Postfix to delegate to Dovecot's LDA. I looked in the documentation and google, but I do not understand the problem. It appears you did not look at the Postfix documentation. According to postconf(5), $virtual_transport specifies the default mail delivery transport and next-hop destination for final delivery to domains listed with $virtual_mailbox_domains. I see you did not define this latter parameter based on your 'postconf -n'. -- Sahil Tandon sa...@tandon.net

Ok, by replacing virtual_maps = proxy:mysql:/etc/postfix/mydomain.cf to
virtual_mailbox_domains = mysql:/etc/postfix/mydomain.cf, it works !!!
But now, the problem is to set the good uid and gid which were defined
like this in postfix
virtual_gid_maps = proxy:mysql:/etc/postfix/mygid.cf
virtual_uid_maps = static:33
With this configuration:
dovecot unix - n n - - pipe
flags=DRhu user=mail:mail argv=/usr/lib/dovecot/deliver -d $(recipient)
socket listen {
master {
path = /var/run/dovecot/auth-master
mode = 0660
user = mail
group = mail
}
I get the following error message
Fatal: setgid(33(www-data)) failed with euid=8(mail), gid=8(mail),
egid=8(mail): Operation not permitted
Any ideas ?
Thanks
Denis
