Limiting bandwidth used by Exim

[Colin Davis]

Hi, I am in a small office that uses an adsl connection for its internet access. We have a debian box with exim installed to send mail. When a large email is send (anything over 1mb really) it hogs all of the upstream, disconnects my ssh sessions etc and making using the internet impossible until the email has gone. I am looking for a way to limit exims use of the available bandwidth. Anybody got any ideas for a quick fix? Any help much appreciated - its driving me mad :-) Col.
