I've tried a few combination and i still can't get it to scan to email.
Here are my settings:
Machine's E-mail Address: email@example.com
SMTP Server Address: smtp.gmail.com
SMTP Server Port Number: 465 (also tried 587, 25, 995)
E-mail Send Authentication: SMTP AUTH (AUTO)
Login Name: firstname.lastname@example.org
I'm not using my printer to receive mails so i left POP3 servers settings empty.
