The emails sent for Save and Continue later is displaying 'via jotform.com'

Also for automatic e-mails, the mention "via jotform.com" always remains present next to the name of the sender. Can we avoid that ? 

I see that the sender emails are configured in your account using normal verification method. So, the emails are being sent using JotForm server. You may configure the sender emails using SMTP method so that your email server shall be used to send the emails and the sender name shall not be displaying 'via jotform.com'.
