To use VSMTP32, you need the following:

• Virtual Advanced v2.10 for DOS. VSMTP32 is for Windows only, so the OS/2 version will not work with it. The BBS software must be installed and setup correctly. Visit the VADV support page to download VADV.
• VSMTP32 was designed for Windows 2000, XP, 2003, Vista and Win7. It should work with earlier versions as well but it has not been tested.
