I updated my project with your latest update (version 6.22), both ww*.prg and .dll files. So, at least the DLL unblocking is now automatic.

>If you don't use lUseSsl then you can use the old non-.NET based email client that requires only wwipstuff.dll. However, these days almost all mail servers require TLS so I wouldn't recommend using the old one because even if you have a mail server that doesn't require SSL (rare) you should be using it because otherwise your logins to that server are not secure.

>>>>>>>>>In my own solution I just upgraded to the very latest version of Newtonsoft.Json.dll file which is version 11.02. However, I have lots of places where different versions of this dll are installed. I'm not sure where this particular version is coming from and what should I do to resolve this issue. Found a few threads on Stackoverlow with the same issue - sounds like I'm in the dll hell now.
