That's pretty short, actually. For a really long log clip, I'd suggest 
using pastebin.

The line numbers don't match up with my source but I can guess where the 
throws happen. The file is 
\Sources_Common\Mail\INET_Clients\CINETClient.cp. Line 950 is in 
DoAuthentication. The throw happens down in SendString. My guess is that 
DoAuthentication is choosing to do so by a plugin DLL and something goes 
wrong there. Maybe Win11 isn't handling the plugin machinery properly.

Another thing you can try is to use WireShark to capture the packets and 
see how far it gets in the exchange. Are you using SSL or STARTTLS to 
connect? What about with IMAP? (I'm trying to understand why IMAP works 
but not SMTP. The low level connection code should be the same.)
