Change directory Papercut watches?

[jzabroski]

Is your feature request related to a problem? Please describe.
We stopped using network interception for papercut and switched to using drop copies, e.g. our App.Config is now:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <system.net>
    <defaultProxy useDefaultCredentials="true" />
    <mailSettings>
      <smtp deliveryMethod="SpecifiedPickupDirectory">
        <specifiedPickupDirectory pickupDirectoryLocation="d:\data\smtp" />
      </smtp>
    </mailSettings>
  </system.net>
  <startup useLegacyV2RuntimeActivationPolicy="true">
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.6.1" />
  </startup>
</configuration>

Our old App.Config was:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <system.net>
    <defaultProxy useDefaultCredentials="true" />
    <mailSettings>
      <smtp>
	      <network defaultCredentials="true" host="localhost" port="25" />
      </smtp>
    </mailSettings>
  </system.net>
  <startup useLegacyV2RuntimeActivationPolicy="true">
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.6.1" />
  </startup>
</configuration>

Describe the solution you'd like
The Papercut GUI is a fantastic tool for reading eml files. I would like to be able to configure it to use a FileSystem Watcher and load any emails drop copied into that folder, without needing to run a network proxy to intercept emails.

Describe alternatives you've considered
Stop using Papercut and look for a different tool?

Additional context
Love this product

@Jaben It looks like

Papercut-SMTP/src/Papercut.Core/Domain/Paths/MessagePathConfigurator.cs

Lines 49 to 62 in 58e08ec

	_templateDictionary = new Dictionary<string, string>(StringComparer.OrdinalIgnoreCase)
	{
	{"BaseDirectory", AppDomain.CurrentDomain.BaseDirectory},
	{"DataDirectory", AppConstants.DataDirectory}
	};
	foreach (
	Environment.SpecialFolder specialPath in
	EnumHelpers.GetEnumList<Environment.SpecialFolder>())
	{
	string specialPathName = specialPath.ToString();
	if (!_templateDictionary.ContainsKey(specialPathName)) _templateDictionary.Add(specialPathName, Environment.GetFolderPath(specialPath));
	}

and

Papercut-SMTP/src/Papercut.Core/Domain/Paths/MessagePathConfigurator.cs

Line 74 in 58e08ec

this.DefaultSavePath = AppDomain.CurrentDomain.BaseDirectory;

is where Papercut UI watches for file system changes and determines where the default save path is.

If there was a configuration setting added to this and some small local storage used in the user's AppData directory, it would be easy to configure and expose a File Chooser Dialog to change the directory.

Thoughts?

BTW, the whole reason I am interested in this, is it seems your email viewer works better than Outlook at viewing emails generated from .NET Framework context. If I use .NET Core and MimeKit, Outlook works great...

[Jaben]

@jzabroski I'm a little confused by this request: Papercut already watches the directory for changes. If you drop EML files in there they will appear.

Also the directory locations are ALREADY configurable via settings.

I'm not sure what you're asking for here...

[jzabroski]

Hmm... I will need to look again. I didn't see a place where I could configure it to save to d:\data\smtp

I clearly dove into the code to try to figure this out, so I'll start there.

For context, you handle EML files better than Outlook does, so I want to use just the GUI without the proxy.

[Jaben]

@jzabroski It's not in the code, it's in the configuration file: Papercut.exe.config. MessagePaths:

Add your path onto the end:

%ApplicationData%\Changemaker Studios\Papercut SMTP;%ApplicationData%\Papercut;%BaseDirectory%\Incoming;%DataDirectory%\Incoming;d:\data\smtp

@Jaben Thank you. I installed Papercut via Chocolatey package "papercut" and none of the programs installed appear to have an App.config file! Somewhat shocking/confusing. It looks like I installed it on April 28, 2020.

[Jaben]

Please open an issue for that problem.

I hate maintaining the Chocolatey package. Since I don't get paid squat to write open source in my very limited free time, I don't do things I hate much.

For now this isn't an issue as a support situation that found a possible new task -- closing for now.
