Configure Proxycap/Proxifier with Email Verification Software Installed In Windows VPS

I have a windows 2016 VPS for which I'm using to run an email verification campaign. The email verification software has been installed in the VPS, but the problem is in order for the software to work, it requires Port 25 to be open, but the VPS provider has it closed. To bypass this problem, I'm attempting to use either Proxifier or Proxycap to route traffic through proxies that does have Port 25 open by it's own respective ISPs. However, I'm having some technical difficulties configuring both Proxycap and Proxifier to work with the email verification software. I have seen such configuration work successfully before, but since I'm not familiar with Proxycap or Proxifier, I'm having difficulty figuring out the proper way to configure it. If I had more free time I would take the time to figure it out, but since I'm quite busy, this is your chance to help me out. So the project is very simple and straightforward: Your job is to configure either Proxycap or Proxifier with my email verification software, so I may use proxies to bypass the port 25 blockage set by the native direct connection of my VPS provider. If you're already familiar with proxcap or proxifier, it shouldn't take you more than one hour to figure out a solution. If you have any questions, please ask me. Thank you.
