hi, we need to set up postfix as an incoming relay which forwards messages via transport to a protected exchange 2007 server. to do this without getting backscatter, we need to check the recipients for validity on exchange server side in AD/LDAP.
this howto from 2003 describes pretty well, what i want to achieve: http://postfix.state-of-mind.de/patrick.koetter/mailrelay/ so, is it still (seven years later) "The right thing™ to do" ? will it work proper with exchange 2007/2010 ? since the usage of "script-generated map-files" will never show a real-time picture of the valid exchange-recipients to postfix, isn't it nicer to do "online LDAP requests" from postfix? maybe this is possible with a LDAP-SASL plugin...? regards MK
