My contact form works when running locally on my computer but doesn't work when published on the domain i bought, the web hosting provider i am using is HostGator.
My site is in asp.net 4 and i am using hotmail as host.
Here is my Web.Config content:
The issue is with ports. You need to have your hosting provider open whatever ports you are going to use or see if you can use an already open port with hot mail.
