With Version 2018.3, you removed the Autodetect SMTP button, and with it, have rendered the Email Tool virtually useless for many people, which is a shame because it is a critical tool for some of us to share reports produced in Alteryx.
In requiring an SMTP path, there are a host of authentication issues that need to be addressed, and we can't seem to figure out how to configure the path and From emails properly to allow the tool to work without errors.
My only solution at this point is to rollback to 2018.2 so I can continue to use the Email tool.
Please address this so we can use the tool as before, or provide the necessary configuration options to allow for proper authentication with popular email services (Gmail, etc.)
