WHD Incoming Mail Settings reset themself

Question

Under E-Mail -> Options -> Incoming Mail I changed the settings of "Create Accounts for Unrecognized Senders" to YES and checked "Use Incoming Mail Account as "From" Address".

But the moment I get a new E-Mail by someone not having a client, the settings are completely reset and obviously no client is created.

Version is "12.5.2 - Build #12.5.2.84"

I also get the following error-message for the rejected mail:

Status Code: ERROR_WHILE_LOCATING_CLIENT

Additional Info: Could not locate or create client with email xxxxxx@mail.com' due to the following error: com.macsdesign.whd.util.ClientLocator$ClientLocatorException: No account exists for e-mail "xxxxxx@mail.com".

Okay... After fiddling around with the settings I somehow got it to work...

At first I tried to use the "only if e-mail matches an accepted domain"-option and added the external domain I wanted to test.

This worked.

After that I simply set it to "Yes", deleted the client, tried again, and it worked.

lastly I deleted the accepted domains, deleted the client, tried again, and it worked.

I also deleted the default incoming and outgoing E-Mail-Accounts and set them to the ones I set up. (I don't know if that had any effect on it though.)

I hope this helps if anyone else ever encounters the same issue.
