Hi Joseph,
You need to have vlan for your mail server so that you can allocate particular bandwidth to that vlan.
Please follow the below config in order to allocate bandwidth to vlan interface.
Policy a specific VLAN number on VLAN interface.
class-map vlan5
match vlan 5
match class-map class-default
policy-map vlan5-limit
class vlan5
police 2000000 250000 exceed-action drop
int vlan5
service-policy input vlan5-limit
After you apply this configuration, the traffic with VLAN 5 coming from any will be policed at 2Mbps.
Please rate the all helpfull posts.

ok lets se if i understand you correct.
you have a mailserver
you want people from the outside to access that mailserver over the internet.
and you want to setup the link so that the mailsystem always gets atleast 512Mbps.
at times when the mailsystem does not use the 512Mb you want the rest of the link to be able to use that data too.
since the users are accessing the from the outside you can not setup how the link behaves.
call your isp and ask them to shape the traffic the way you want it.
you can help out with setting up limits and quality of service from the different lans that they do not take more than 1,5Gbps total bandwith of the internet link.
Good luck

Thank you for the rating!
I feel I need to clarify why the isp needs to do this since it is not realy clear in my old post.
Its because when the traffic from the outside users hits your router it has already traversed the link so it is to late to shape it in your end.
Good luck
