I posted over the weekend about problems with Outlook
failing SPA-NTLM once, each time it sends email, and
then (apparently) succeeding SPA-NTLM authentication
anyway.

Apparently, Outlook is NOT sending the configured/specified
username and password on the first try (but since SPA-NTLM
is encrypted I don't know quite how to prove that.)

Do you have any other evidence or pointers to Outlook or
Outlook Express trying the "wrong" authentication before
it does the correct method/user/password combination?
