Exchange distribution list saturates internet connection

We have sent almost 20 mails to a distribution lists (over 200 users per mail) and our ADSL line has gone down (very slow or stopped)
if we disable the outgoing mail queue we can navigate to internet without problems.

What do we have to activate to let this 20 mails to be delivered with an assigned bandwith limit?, or how to make exchange to deliver only one mail at a time?

Thanks

There is very little that you can do with Exchange. This is why Exchange makes such a poor tool for any kind of bulk email distribution.
If you have any QOS on the router then you could restrict the traffic that way, but there is almost nothing that can be done with Exchange.

What about changing the parameter in Protocols->"SMTP"->Default SMTP site->Properties->Delivery Tab->Outbound connections->"Limit number of connections to"
Setting this value to 1 will restrict exchange to deliver only one mail at once?
That would be a nice start.

That will bring email message flow to a halt, both inbound and outbound.
Imagine a 10 lane motorway suddenly restricted to one lane. Certainly not a setting I would even consider making.
