As every Exchange requires an Acive Directory it does not matter if there is one exchange or many instances Here is a perl-script that pulls out all valid email-addresses and creates a file usable for postfix relay_receipients http://www-personal.umich.edu/~malth/gaptuning/postfix/getadsmtp.pl Run it hourly, do a postmap afterwords and you are done ;-) Regards Sebastian Ries -- ------------------------------------------------------------ DT Netsolution GmbH - Talaeckerstr. 30 - D-70437 Stuttgart Tel: +49-711-849910-36 Fax: +49-711-849910-936 WEB: http://www.dtnet.de/ email: sebastian.r...@dtnet.de
