Hallo,

Saya mengharapkan adanya feature bandwidth throttling (bandwidth
shaping) di Wingate atau Winroute, yg nantinya bisa dikombinasi dg
MDaemon utk bandwidth priorities, eh ternyata MDaemon malah mendahului :

MDaemon 6.70b

* BANDWIDTH THROTTLING *

A basic system for policing the consumption of bandwidth has been
added. A new option available from the Setup menu will allow you to
throttle the rate at which sessions (or services) progress.  The system
is calibrated in kilobytes per second (KB/s).  A value of ZERO means
apply no limit to the speed at which a session (or service) progresses
(thus    making use of the maximum amount of available bandwidth).  A
value of 10 will force MDaemon to deliberately throttle back on the
speed of transmission so as to remain at or slightly above 10 KB/s.

You can set different rates for each of MDaemon's major services on
a per-domain basis.  You can also set limits on local connections by
selecting "Local traffic" from the drop down box.  This will allow
you to create special bandwidth settings which will take effect if
the connection is either from or to a local IP or domain name. 
Screens have been created to allow you to configure your own list of
local IP and domain name addresses.

It is possible to configure bandwidth throttling for Gateway domains
as well.  Since Gateway domains do not have a specific IP address
associated with them, MDaemon must use the value passed in the RCPT
command to determine if an inbound SMTP session is bound for a Gateway  
domain or not.  If it is, then inbound SMTP bandwidth throttling will  
be applied.  Due to the limitations of SMTP, if even one recipient of  
a multiple recipient message is destined for a Gateway domain then the 
entire session will be throttled.

Finally, you can elect to apply throttling settings on a per-session
or per-service basis.  When using the per-session mode each session
will be independently throttled to the associated rate.  The total
bandwidth consumed by multiple instances of the same session type
(for example, 5 inbound SMTP sessions to the same domain) could
exceed the configured value.  The limitation in this case is
per-session.  When configured to throttle bandwidth on a per-service
basis MDaemon will monitor the combined use of all instances of the
same session type and allocate fractions of the total bandwidth
allowed in equal amounts to each. This will allow you to set a limit
on an entire service (for example, outbound SMTP to or from a particular
domain).  Multiple sessions will then share the configured maximum
bandwidth equally.

Bursts of activity at the beginning of a session can and will exceed
the fixed limits. Throttling takes place and becomes more defined as
the session progresses.
