open Exchange systm manager--> properties of default smtp virtual srver--> delivery--> outbound connection_> hop-> increase the hop count to the one you need.
by default its 30.
you need to set up PTR record for your connecting ip. you need to contact your ISP for the same,. well this can cause issues for outbound mail flow for the domains who ask for reverse dns...
Is this happening for all emails or only when emailing a particular recipient? is internal email working fine(shouldn't matter but still..)
