I’m trying to setup eNewsletter and think I’m using

I’m trying to setup eNewsletter and think I’m using the wrong syntax (SMTP account). The email is content@newmednews.com; setup via Bluehost. What is the correct syntax for:
General Settings From email
SMTP outgoing server
SMTP username
iLetter, Settings, From email

I’ve used a bunch of combinations but still get the “Note of SMTP Method” error message
