I second the passive method. There\'s a convenient Perl script that queries your AD and converts the data to a recipient list needed by postfix. http://www-personal.umich.edu/~malth/gaptuning/postfix/ We\'re running postfix/ amavisd-new on an email-gateway that relays mail to several backend mail-servers [postfix/openLDAP, Exchange/AD]. That\'s why we are using a mixture of active LDAP queries for Linux based users and passive queries for Windows based users. To query multiple Exchange/ AD servers we are using multiple instances of the script that drops the output into different files within the postfix directory [ad_relay_recipients_...]. You only need to modify the perl script slightly to achive this. The corresponding \"relay_recipient_maps\" config looks as follows: relay_recipient_maps = hash:/etc/postfix/ad_relay_recipients_<server01>, hash:/etc/postfix/ad_relay_recipients_<server02>, ldap:ldap.relay A cronjob calls each perl script separately like 34 3 * * * root /usr/local/sbin/postfix.get_relay_recipients_from_<server01>; /usr/sbin/postmap /etc/postfix/ad_relay_recipients_<server01> You don\'t need to restart postfix, because it rereads the database files if they\'re changed.
