limiting maximum outbound smtp sessions in Exchange

Hi,

We're running Exchange 2003. My sales team want to send email announcments to all our customers at once. Customers have agreed to this BTW.

When my Sales Director sends one email to 700 recipients the Exchange server then attempts to establish outbound SMTP sessions with all 700 at once. Is there a way I can limit this to say 30 at once? I don't mind that it will take 4 days to send, just glad it won't have taken our DSL down!

Thanks
Andrew

There is an option in the properties of the default smtp virtual server under the delivery tab when you click on the outbound connections button

the check box is called "limit number of connections to"

you can change that to your business requirement

Thanks for that!

the only problem i have left is there are nearly 600 outbound SMTP emails frozen in the queue.

If i unfreeze them will they all go, or stick to my new outbound limit?

Cheers
