Configuration of Postfix

[quentin]

Hi,
pls, can somebody help me with setting of postfix.
I tried this settings:

local_recipient_maps = proxy:unixasswd.byname
alias_maps = hash:/etc/postfix/cyrus_recipients
mailbox_transport = lmtp:unix:/var/run/cyrus/socket/lmtp
smtpd_sasl_auth_enable = yes
It is working, but I want to authorize against db.

But I am sure, that I can use solution like in 8.6.4
mailbox_transport = lmtp:unix:/var/run/cyrus/socket/lmtp
virtual_alias_domains = mysql:/etc/postfix/ox_domains.cf
virtual_alias_maps = mysql:/etc/postfix/ox_user_aliases.cf, mysql:/etc/postfix/ox_aliases.cf, mysql:/etc/postfix/ox_resource_aliases.cf, mysql:/etc/postfix/ox_group_aliases.cf
smtpd_sender_restrictions = check_sender_access mysql:/etc/postfix/ox_externaldomaincheck.cf
smtpd_restriction_classes = local_only
local_only = check_recipient_access mysql:/etc/postfix/ox_domains.cf, reject
smtpd_recipient_restrictions = check_sender_access mysql:/etc/postfix/ox_senderrestrictions.cf, permit_sasl_authenticated, permit_mynetworks, reject_unauth_destination

Can somebody help me please with database queries???

PS: Sorry for my bad English.
