I want to limit the max smtp-connections the postfix-daemon can process
simultanously - or even better - the total bandwidht used by postfix.

Current problem: a postfix-server is connected to internet on a
500k-uplink DSL-Connection. Now a user sends a 30MB-mail to 1000
recipients. This means 30Ggigs of mail over a 500k-connection.
The line is dead with traffic.

I guess a limit on connections would not help too much, but bring at
least some performance-gain to the connection. I didnt find an option to
limit the max. number of smtp-processes that applies to the queues as
well.
And I didnt find a bandwith-option.

Any idea (beside using a smart-relay at the ISP, which would be smart
indeed :) ?

thnx,
peter
