So I've been running CF9 on Linux for a while and using CFMail to send email through a client's Exchange 2010 server.
We're attempting to migrate to CF10 on Win2008, IIS7.5. Everything is set and ready to go except I can't get CF10 to verify the mail connection? I've got both mail settings (CF9 and CF10) set the exact same way and can view them open side by side and verify they're identical. However, while the CF9 verifies successfully the CF10 system fails??
I tried sending through CFMail tags while specifying the server credentials and see this in the CF10 log:
"javax.mail.AuthenticationFailedException: No authentication mechansims supported by both server and client"
What does this mean? I know my authentication credentials are correct because I'm able to connect in CF9.
I've turned off all firewalls and still nothing. So, I then tried installing CF10 on my Mac laptop. It, too, will not verify the mail connection!
Is there a known problem with CF10 connecting to an Exchange mail server?
Any ideas?
