Commented Issue: Constant Crashes on Win 7 64-bit [6025]

smtp4dev crashes almost evertime mail is sent through. I'm running Win 7 64-bit and using PHP 5.3's email function on Apache 2.2. I don't see any log files or anything that might provide some insight into the issue in the installation directory. is there a way to do a crash report?

I had the same error so I downloaded the source and ran it in debug mode. Turns out that in my case smtp4dev was trying to retrieve a server certificate (for TLS) that didn't exist, so it crashed with the ArgumentNullException. My solution was to UNCHECK the "STARTTLS (Explicit SSL/TLS)" option in the Server tab of the options dialog.

Good luck to you.
