There is definitely an error when setting to SMTP. I am using both Mailpoet and WP Mail SMTP with the SMTP settings and both are fine, but EM is throwing a server error.
Switching to WP Mail seems to be working, but now WP Mail SMTP ist throwing the message, there is the recipient email missing, so it seems EM has an issue with the correct email setup for sending mails.
Here is what I got in the debug log:
