Send e-mail on two-factor authentication

I used to send e-mail from the KNIME Analytics Platform by using the “Send Email” node. I use “” as the SMTP Host and “587” as the SMTP Port. Things worked fine until my company enabled two-factor authentication. Since then, the “Send Email” node is failing. Here is the error message:

ERROR Send Email 0:1079 Execute failed: Error while communicating with the smtp server: javax.mail.AuthenticationFailedException

Have anyone faced a similar issue? Any suggestions?

Thanks in advance

Hi Edwin,

I found this article regarding send mail, and was wondering if you could check with your admins whether or not the user they are using to send from has this checkbox enabled?



Thanks Zack! I will check it and let you know.
