Traffic Shaper on outgoing emails?

honk
hi forum,

ASG220 with exchange 2003 behind. mail security activated - everything is fine, except when a newsletter is send out. the mails are in the SMTP spooler on the ASG and delivery is in process - this cuts down the complete internet traffic, meaning that even opening a website is not possible anymore. 
the uplink is on it's limit (512kbit/sec)

is there a possibility to shape down the traffic, e.g. that outgoing mails from the ASG must not take more than 256kbit/sec, so that surfing is still possible while mails are delivered?

if so (and i think there should be something like that) it would be great if someone gives my guidance.

thanks

    A couple things here.  First, it's easy to set the Bandwidth Pool on the wrong interface, so check that.  Second, I'm not a big fan of limiting bandwidth, so I always make it a habit to look for the problem caused.  In this thread, it seems like the issue is outbound browsing and DNS requests, and that the inbound pipe is almost empty.

    So, I would kill the QoS rule that limits email traffic.  Next add a new services group "Browsing" that includes everything in "Web Surfing" plus DNS.  Finally, create a rule on the External interface guaranteeing 128k to 'Any -> Browsing -> Any'.

    Did that give you the results you were looking for?

    Cheers - Bob
