Hi
we use here since ages
virtual_mailbox_domains = proxy:ldap:/etc/postfix/ldap-domain.cf
and if that is positive (i.e. the domain is local)
virtual_alias_maps = proxy:ldap:/etc/postfix/ldap-alias.cf
with
virtual_transport = virtual

I am trying to figure out what is the best solution in order to filter
incoming e-mail on a front-end relay server quite heavily loaded (100.000
messages / day).
Even if you assume that all those messages will be sent within 8 hours
(business time) it will boil down to ~ 3.5 msg/sec. Server hardware can do
that easily.
We are using LDAP querry in amavisd-new in order to check if the e-mail
account exists in our LDAP DB.
Bad idea.

Since update of our amavisd-new server to version 2.7.0 we are having
problem with the LDAP lookup.
I was wondering if It was not better to do this lookup before delivering the
e-mail to the amavisd process ?
Good idea. Reject any message that can't be delivered immediately. That's
cheap. It takes place in the SMTP session before the payload has been sent and
before a content filter, such as amavis, does ressource intensive filtering.
If the answer is positive, should I use the "local_recipient_maps" parameter
or is there another more efficient method to be used ?
Depends on the namespace the recpient domain is in.
