Hi Rick,
We're changing our internal SMTP provider and I've been having some problems getting a test to go through. A couple of questions for you; is the venerable WWWM using your most recent SMTP implementation; and is there a way to get more verbose logging from the SMTP call.
TIA
.NET has support for Trace Routing which you can enable in the app.config file for the application. You can search for how to set that up or use your favorite LLM to set up the config for that.
If I recall it's a bunch of complex XML configuration settings in the config file that allow you to specify a trace file and trace verbosity. The trace is pretty low level so there's a lot of noise in addition to the message and protocol headers - it's not easy to find what you want because the output is copious but if you're dealing with a connect issue that might actually a bonus.
FWIW, WM is a .NET 4.x application so the older .NET Framework network tracing works with it.
