---------------------
My main Q? is that, what benifits i am getting after enable this
<DDATA_COMPRESS>. And how do i
check that.
To check it use telnet mailserver 25 and issue a "EHLO dude".
If you see a DATAZ feature it is enabled.
Thats good .
The benefits are less bytes transported. Emails can be compressed
massivly. I see results between 40 and 84% savings (most around 50-60%).
My Q? that how you have check this. I have check this feture in my m/c by
sending 37MB attachhment mail
without < DDATA_COMPRESS > option it's take 3 min ~ approximately and also test
same thing after enableing
<DDATA_COMPRESS> option. it's take 3 min ~ approximately. whats the
diffe.............man
and one more thing. Is it required that both side this option should be enable?
Please give me some good
test scenario so i can test. I want to use this option on production server.
We use this feature for a loose mail cluster setup where the nodes are
connected via ADSL lines where the bandwith is very limited.
With Cheers,
