I'd like to check incoming emails against some 3rd-party DNSBLs using rsync rather than internet DNS queries. Noticed, though, that rsync is not installed with Messaging Gateway (we're using the Messaging Gateway VM appliance (version 9.5.3) installed on VMWare vSphere 4 server). My questions are 1) Is it supported? and 2) How should I go about installing it?
Thanks for the help
Shaun
