Question

Does CFMAIL support Windows Integrated Authentication

We are upgrading our servers and for CFMAIL we now need to connect to the server using username and password.  With Powershell everything is working and I received the email.

 

With CFMail, I always run into this issue "SMTPSenderFailedException: 550 Submitter failed to authenticate "

 

The only thing I could find is this old post Charlie Arehart

So is this still an issue with CF 2023?

    Yes, it's still an issue, because Windows Authentication is proprietary. The easiest way to get around this is to install a local SMTP server that doesn't require it and limit access to that server.
