Hi, so far I've setup multiple postfix instances being final destinations for one or more domains and I have successfully setup some postfix instances being proxying spam/virus checking gateways only.
For final destination delivery, we are utilizing LDAP that is all well integrated using virtual_mailbox_domains etc. When configured as a proxying spam/virus checking gateway, I've been using a combination for transport_maps and relay_recipient_maps and relay_domains, ie. relay_domains: @example.com OK transport_maps: example.com smtp:[smtp.example.com] relay_recipient_maps: @example.com x Now what I need to do now is to integrate the proxying gateway capabilities into our ordinary "virtual", LDAP based environment. I would like to specify the domains "proxying only" domains as a virtual_mailbox_domain and subsequently configure a dedicated (virtual) transport for such domains. Now the only option I find for such a task is virtual_transport, but as it seems, this option is not table capable (or am I wrong)? Ideally, I would configure it like this: virtual_transport = hash:/usr/local/etc/postfix/virtual_transport_map with "virtual_transport_map" then containing something like this example.com smtp:[smtp.example.com] * lmtp:unix:private/dovecot-lmtp But this doesn't seem to work. Any clues appreciated :)
