We have utilized your Mail.dll. Windows defender has started to kick out the application as a trojan Wacatac.B!ml. We are running Windows 11 and have updated windows defender definitions. Have you seen this before?
Mail.dll is definitely not a trojan.
All Mail.dll versions are green on Virus Total:
I additionally scanned it using Windows Defender with the latest definitions (as of 2022/04/19) - no threats detected.
Do you have any screenshot it actually happens?
