The "From" email address is set up by Barilliance Support. Please contact support@barilliance.com for assistance in setting the address. 

If you would like to change your current "From" email address, please specify if you would like to change only the prefix of the email address, or if you want to completely change the address, including the domain. 

If you want to change only the prefix, please send us the new address, we will send you a verification email for it and replace it once you verify the email. 

If you want to change the domain, please note you will need to change the SPF record to the new domain, as described here.
