Classic asp developer to fix email form not sending

We have recently moved a number of sites to a new hosting environment and have found that the email forms on each website no longer send out emails. We have 2 sites that need immediate attention and possibly another 2 to correct. All sites are built using the same cms system and all use cdosys local or cdonts so fix one and it should be easy to correct the rest. The first site we need help with is solsearchersproperty.com which has three email forms.
