To check it use telnet mailserver 25 and issue a "EHLO dude". If you see a DATAZ feature it is enabled. The benefits are less bytes transported. Emails can be compressed massivly. I see results between 40 and 84% savings (most around 50-60%). We use this feature for a loose mail cluster setup where the nodes are connected via ADSL lines where the bandwith is very limited. -- :wq Claudio
