Hi Community.

My iflow should send an welcome letter via email but im getting the error:

javax.mail.AuthenticationFailedException: 535 Authentication credentials invalid<br>

The method im using for the email sender is like this:

Recently i changed the credentials for the email in "From:" and i've been having the error since, also the credential i use is "Plain User/Password" and the credentials are updated with the new password.

Any ideas about this issue?
