Actually, the path to Sendmail is fairly standard, although it can vary.
To find the paths to binaries such as Sendmail, Perl, Python, etc... and other useful information about your account set up, go to you CNC and click on the "Server Info" link.
Your CNC is at
http://www.example.com/CNC/
except you need to replace example.com with your actual domain.
Hope this helps,
