Let me ask you one more question, to clarify something.

If I do not use the SSL/TLS option (that is, I have loSmtp.lUseSsl = .F.), does object wwSmtp still uses the wwDotnetBridge.dll? Or this DLL is only used when the .lUseSsl is set to .T. ?

TIA

>>>Naomi's issue was likely different that what you're looking at. For her it was finding the right EXE to add the .config file to (the launching EXE) that allows access of the wwDotnetBridge.dll over a network.

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.
